apache_note -- apache request note¸¦ ¼³Á¤Çϰųª Àоî¿Â´Ù.
string apache_note
(string note_name, string [note_value]);
apache_note() is an Apache-specific function which gets and sets values in a request's notes table. If called with one argument, it returns the current value of note note_name. If called with two arguments, it sets the value of note note_name to note_value and returns the previous value of note note_name.
getallheaders -- ¸ðµç HTTP request header¸¦ ºÐ¼®ÇÏ¿© Àоî¿Â´Ù.
array getallheaders
(void);
This function returns an associative array of all the HTTP headers in the current request.
Example 1. GetAllHeaders() Example
|
This example will display all the request headers for the current request.
Note: GetAllHeaders() is currently only supported when PHP runs as an Apache module.
virtual -- Apache sub-request¸¦ ¼öÇàÇÑ´Ù.
int virtual
(string filename);
virtual() is an Apache-specific function which is equivalent to <!--#include virtual...--> in mod_include. It performs an Apache sub-request. It is useful for including CGI scripts or .shtml files, or anything else that you would parse through Apache. Note that for a CGI script, the script must generate valid CGI headers. At the minimum that means it must generate a Content-type header. For PHP files, you should use include() or require().
array -- ¹è¿À» ¸¸µç´Ù.
array array(...);
Returns an array of the parameters. The parameters can be given an index with the => operator.
Note that array() really is a language construct used to represent literal arrays, and not a regular function.
The following example demonstrates how to create a two-dimensional array, how to specify keys for associative arrays, and how to skip-and-continue numeric indices in normal arrays.
Example 1. array() example $fruits = array( "fruits" => array("a"=>"orange","b"=>"banana","c"=>"apple"), "numbers" => array(1, 2, 3, 4, 5, 6) "holes" => array("first", 5 => "second", "third") ); |
See also: list().
array_walk -- ¹è¿ÀÇ °³°³ÀÇ ¿ø¼Ò¿¡ ƯÁ¤ ÇÔ¼ö¸¦ Àû¿ëÇÏ¿© ¼öÇàÇÑ´Ù.
int array_walk
(array arr, string func);
Applies the function named by func to each element of arr. The elements are passed as the first argument of func; if func requires more than one argument, a warning will be generated each time array_walk() calls func. These warnings may be suppressed by prepending the '@' sign to the array_walk() call, or by using error_reporting().
Note that func will actually be working with the elements of arr, so any changes made to those elements will actually be made in the array itself.
Example 1. array_walk() example

arsort -- ¹è¿À» ¿ª¼øÀ¸·Î Á¤·ÄÇÏ°í index associationÀ» À¯ÁöÇÑ´Ù.
void arsort(array array);
This function sorts an array such that array indices maintain their correlation with the array elements they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant.
Example 1. arsort() example $fruits = array("d"=>"lemon","a"=>"orange","b"=>"banana","c"=>"apple"); arsort($fruits); for(reset($fruits); $key = key($fruits); next($fruits)) { echo "fruits[$key] = ".$fruits[$key]."\n"; } |
This example would display: fruits[a] = orange fruits[d] = lemon fruits[b] = banana fruits[c] = apple The fruits have been sorted in reverse alphabetical order, and the index associated with each element has been maintained.
See also: asort(), rsort(), ksort(), and sort().

int count(mixed var);
Returns the number of elements in var, which is typically an array (since anything else will have one element).
Returns 0 if the variable is not set.
Returns 1 if the variable is not an array.

next -- ¹è¿ÀÇ internal pointer¸¦ Çϳª ÀüÁø½ÃŲ´Ù.
mixed next(array array);
Returns the array element in the next place that's pointed by the internal array pointer, or false if there are no more elements.
next() behaves like current(), with one difference. It advances the internal array pointer one place forward before returning the element. That means it returns the next array element and advances the internal array pointer by one. If advancing the internal array pointer results in going beyond the end of the element list, next() returns false.

mixed prev(array array);
Returns the array element in the previous place that's pointed by the internal array pointer, or false if there are no more elements.
prev() behaves just like next(), except it rewinds the internal array pointer one place instead of advancing it.
See also: current(), end() next() and reset()

JDToGregorian -- Julian Day Count¸¦ Gregorian date·Î º¯È¯
string jdtogregorian(int julianday);
Converts Julian Day Count to a string containing the Gregorian date in the format of "month/day/year"
GregorianToJD -- Gregorian date¸¦ Julian Day Count·Î º¯È¯
int gregoriantojd(int month, int day, int year);
Valid Range for Gregorian Calendar 4714 B.C. to 9999 A.D.
Although this software can handle dates all the way back to 4714 B.C., such use may not be meaningful. The Gregorian calendar was not instituted until October 15, 1582 (or October 5, 1582 in the Julian calendar). Some countries did not accept it until much later. For example, Britain converted in 1752, The USSR in 1918 and Greece in 1923. Most European countries used the Julian calendar prior to the Gregorian.
Example 1. Calendar functions <?php $jd = GregorianToJD(10,11,1970); echo("$jd\n"); $gregorian = JDToGregorian($jd); echo("$gregorian\n"); ?> |

Valid Range for Julian Calendar 4713 B.C. to 9999 A.D.
Although this software can handle dates all the way back to 4713 B.C., such use may not be meaningful. The calendar was created in 46 B.C., but the details did not stabilize until at least 8 A.D., and perhaps as late at the 4th century. Also, the beginning of a year varied from one culture to another - not all accepted January as the first month.
JDToJewish -- Julian Day Count¸¦ the À¯´ë Calendar·Î º¯È¯.

Returns the Unix timestamp corresponding to the arguments given. This timestamp is a long integer containing the number of seconds between the Unix Epoch (January 1 1970) and the time specified.
Arguments may be left out in order from right to left; any arguments thus omitted will be set to the current value according to the local date and time.
MkTime is useful for doing date arithmetic and validation, as it will automatically calculate the correct value for out-of-range input. For example, each of the following lines produces the string "Jan-01-1998".
Example 1. mktime() example echo date( "M-d-Y", mktime(0,0,0,12,32,1997) ); echo date( "M-d-Y", mktime(0,0,0,13,1,1997) ); echo date( "M-d-Y", mktime(0,0,0,1,1,1998) ); |

dbase_create -- dBase database¸¦ »ý¼ºÇÑ´Ù.
int dbase_create(string filename, array fields);
The fields parameter is an array of arrays, each array describing the format of one field in the database. Each field consists of a name, a character indicating the field type, a length, and a precision.
The types of fields available are:
L - Boolean. These do not have a length or precision.
M - Memo. (Note that these aren't supported by PHP.) These do not have a length or precision.
D - Date (stored as YYYYMMDD). These do not have a length or precision.
N - Number. These have both a length and a precision (the number of digits after the decimal point).
C - String.
If the database is successfully created, a dbase_identifier is returned, otherwise false is returned.
Example 1. Creating a dBase database file
|
dbase_open -- dBase database¸¦ ¿¬´Ù.
int dbase_open(string filename, int flags);
The flags correspond to those for the open() system call. (Typically 0 means read-only, 1 means write-only, and 2 means read and write.)
Returns a dbase_identifier for the opened database, or false if the database couldn't be opened.
dbase_close -- dBase database¸¦ ´Ý´Â´Ù.
bool dbase_close(int dbase_identifier);
Closes the database associated with dbase_identifier.
dbase_pack -- dBase database¸¦ packÇÑ´Ù.
bool dbase_pack(int dbase_identifier);
Packs the specified database (permanently deleting all records marked for deletion using dbase_delete_record().
dbase_add_record -- dBase database¿¡ ÇÑ record¸¦ ´õÇÑ´Ù.
bool dbase_add_record(int dbase_identifier, array record);
Adds the data in the record to the database. If the number of items in the supplied record isn't equal to the number of fields in the database, the operation will fail and false will be returned.
dbase_delete_record -- dBase database¿¡¼ ÇÑ record¸¦ »èÁ¦ÇÑ´Ù
bool dbase_delete_record(int dbase_identifier, int record);
Marks record to be deleted from the database. To actually remove the record from the database, you must also call dbase_pack().
dbase_get_record -- dBase database¿¡¼ ÇÑ record¸¦ Àоî¿Â´Ù.
array dbase_get_record(int dbase_identifier, int record);
Returns the data from record in an array. The array is indexed starting at 0, and includes an associative member named 'deleted' which is set to 1 if the record has been marked for deletion (see dbase_delete_record().
Each field is converted to the appropriate PHP type. (Dates are left as strings.)
dbase_numfields -- dBase databaseÀÇ fieldÀÇ °³¼ö¸¦ ±¸ÇÑ´Ù.
int dbase_numfields(int dbase_identifier);
Returns the number of fields (columns) in the specified database. Field numbers are between 0 and dbase_numfields($db)-1, while record numbers are between 1 and dbase_numrecords($db).
Example 1. Using dbase_numfields()
|
dbase_numrecords -- fdBase databaseÀÇ recordÀÇ °³¼ö¸¦ ±¸ÇÑ´Ù.
int dbase_numrecords(int dbase_identifier);
Returns the number of records (rows) in the specified database. Record numbers are between 1 and dbase_numrecords($db), while field numbers are between 0 and dbase_numfields($db)-1.

Example 1. dbm example
|
dbmopen -- dbm database¸¦ ¿¬´Ù.
int dbmopen(string filename, int flags);
The first argument is the full-path filename of the dbm file to be opened and the second is the file open mode which is one of "r", "n" or "w" for read, new (implies write) and write respectively.
Returns an identifer to be passed to the other dbm functions on success, or false on failure.
If ndbm support is used, ndbm will actually create filename.dir and filename.pag files. gdbm only uses one file, as does the internal flat-file support, and Berkeley db creates a filename.db file. Note that PHP does its own file locking in addition to any file locking that may be done by the dbm library itself. PHP does not delete the .lck files it creates. It uses these files simply as fixed inodes on which to do the file locking. For more information on dbm files, see your Unix man pages, or obtain GNU's gdbm from ftp://prep.ai.mit.edu/pub/gnu.
Example 1. dbm example

dbmclose -- dbm database¸¦ ´Ý´Â´Ù.
bool dbmclose(int dbm_identifier);
Unlocks and closes the specified database.
dbmexists -- dbm database¿¡ ÁÖ¾îÁø key¿¡ ÇØ´çÇÏ´Â °ªÀÌ ÀÖ´ÂÁö ¾Ë¾Æº»´Ù.
bool dbmexists(int dbm_identifier, string key);

dbmfetch -- dbm database¿¡¼ ÁÖ¾îÁø keyÀÇ value¸¦ Àоî¿Â´Ù.
string dbmfetch(int dbm_identifier, string key);
Returns the value associated with key.
dbminsert -- dbm database¿¡ keyÀÇ value¸¦ »ðÀÔÇÑ´Ù.
int dbminsert(int dbm_identifier, string key, string value);
Adds the value to the database with the specified key.
Returns -1 if the database was opened read-only, 0 if the insert was successful, and 1 if the specified key already exists. (To replace the value, use dbmreplace().)
dbmreplace -- dbm database¿¡¼ keyÀÇ value¸¦ ¹Ù²Û´Ù.
bool dbmreplace(int dbm_identifier, string key, string value);
Replaces the value for the specified key in the database.
This will also add the key to the database if it didn't already exist.
dbmdelete -- dbm database¿¡¼ keyÀÇ value¸¦ »èÁ¦ÇÑ´Ù.
bool dbmdelete(int dbm_identifier, string key);
Deletes the value for key in the database.
Returns false if the key didn't exist in the database.
dbmfirstkey -- dbm databaseÀÇ Ã¹ ¹ø° key¸¦ °Ë»öÇÑ´Ù.
string dbmfirstkey(int dbm_identifier);
Returns the first key in the database. Note that no particular order is guaranteed since the database may be built using a hash-table, which doesn't guarantee any ordering.
dbmnextkey -- dbm databaseÀÇ ´ÙÀ½ key¸¦ °Ë»öÇÑ´Ù.
string dbmnextkey(int dbm_identifier, string key);
Returns the next key after key. By calling dbmfirstkey() followed by successive calls to dbmnextkey() it is possible to visit every key/value pair in the dbm database. For example:
Example 1. Visiting every key/value pair in a dbm database. $key = dbmfirstkey($dbm_id); while ($key) { echo "$key = " . dbmfetch($dbm_id, $key) . "\n"; $key = dbmnextkey($dbm_id, $key); } |

string dblist(void);
chdir -- ÇöÀç directory¸¦ ¹Ù²Û´Ù.
int chdir(string directory);
Changes PHP's current directory to directory. Returns FALSE if unable to change directory, TRUE otherwise.
dir -- directory class
new dir(string directory);
A pseudo-object oriented mechanism for reading a directory. The given directory is opened. Two properties are available once directory has been opened. The handle property can be used with other directory functions such as readdir(), rewinddir() and closedir(). The path property is set to path the directory that was opened. Three methods are available: read, rewind and close.
Example 1. Dir() Example $d = dir("/etc"); echo "Handle: ".$d->handle."<br>\n"; echo "Path: ".$d->path."<br>\n"; while($entry=$d->read()) { echo $entry."<br>\n"; } $d->close(); |
closedir -- directory handleÀ» ´Ý´Â´Ù.
void closedir(int dir_handle);
Closes the directory stream indicated by dir_handle. The stream must have previously been opened by opendir().
opendir -- directory handleÀ» ¿¬´Ù.
int opendir(string path);
Returns a directory handle to be used in subsequent closedir(), readdir(), and rewinddir() calls.
readdir -- directory handle·Î ºÎÅÍ Ç׸ñÀ» Àоî¿Â´Ù.
string readdir(int dir_handle);
Returns the filename of the next file from the directory. The filenames are not returned in any particular order.
Example 1. List all files in the current directory
|
rewinddir -- directory handleÀ» directoryÀÇ ½ÃÀÛ À§Ä¡·Î µÇµ¹¸°´Ù.
void rewinddir(int dir_handle);
Resets the directory stream indicated by dir_handle to the beginning of the directory.
dl -- PHP extensionÀ» ½ÇÇàÁß¿¡ loadÇÑ´Ù.
int dl(string library);
Loads the PHP extension defined in library. See also the extension_dir configuration directive.
escapeshellcmd -- shellÀÇ metacharacterµéÀ» escapeÇÑ ´Ù.
string escapeshellcmd(string command);
EscapeShellCmd() escapes any characters in a string that might be used to trick a shell command into executing arbitrary commands. This function should be used to make sure that any data coming from user input is escaped before this data is passed to the exec() or system() functions. A standard use would be:
system(EscapeShellCmd($cmd))
exec -- ¿ÜºÎ programÀ» ½ÇÇàÇÑ´Ù.
string exec(string command, string array, int return_var);
Exec executes the given command, however it does not output anything. It simply returns the last line from the result of the command. If you need to execute a command and have all the data from the command passed directly back without any interference, use the PassThru() function.
If the array argument is present, then the specified array will be filled with every line of output from the command. Note that if the array already contains some elements, exec() will append to the end of the array. If you do not want the function to append elements, call unset() on the array before passing it to exec().
If the return_var argument is present along with the array argument, then the return status of the executed command will be written to this variable.
Note that if you are going to allow data coming from user input to be passed to this function, then you should be using EscapeShellCmd() to make sure that users cannot trick the system into executing arbitrary commands.
See also system(), PassThru(), popen() and EscapeShellCmd().
system -- ¿ÜºÎ programÀ» ½ÇÇàÇÏ°í ±× °á°ú¸¦ Ãâ·ÂÇÑ´Ù.
string system(string command, int return_var);
System() is just like the C version of the function in that it executes the given command and outputs the result. If a variable is provided as the second argument, then the return status code of the executed command will be written to this variable.
Note, that if you are going to allow data coming from user input to be passed to this function, then you should be using the EscapeShellCmd() function to make sure that users cannot trick the system into executing arbitrary commands.
The System() call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a server module.
If you need to execute a command and have all the data from the command passed directly back without any interference, use the PassThru() function. See also the exec() and popen() functions.
passthru -- ¿ÜºÎ ÇÁ·Î±×·¥À» ½ÇÇàÇÏ°í ±× °á°ú¸¦ Á÷Á¢ (Áöü¾øÀÌ) Ãâ·ÂÇÑ´Ù.
string passthru(string command, int return_var);
The PassThru() function is similar to the Exec() function in that it executes a command. If the return_var argument is present, the return status of the Unix command will be placed here. This function should be used in place of Exec() or System() when the output from the Unix command is binary data which needs to be passed directly back to the browser. A common use for this is to execute something like the pbmplus utilities that can output an image stream directly. By setting the content-type to image/gif and then calling a pbmplus program to output a gif, you can create PHP scripts that output images directly.
See also exec() and fpassthru().

filepro -- map fileÆÄÀÏÀ» ÀÐ°í °ËÁõÇÑ´Ù.
bool filepro(string directory);
This reads and verifies the map file, storing the field count and info.
No locking is done, so you should avoid modifying your filePro database while it may be opened in PHP.
filepro_fieldname -- fieldÀÇ À̸§À» ±¸ÇÑ´Ù.
string filepro_fieldname(int field_number);
Returns the name of the field corresponding to field_number.

int filepro_rowcount(void);
Returns the number of rows in the opened filePro database.
See also filepro().
basename -- pathÁß name ºÎºÐÀ» ±¸ÇÑ´Ù.
string basename(string path);
Given a string containing a path to a file, this function will return the base name of the file.
On Windows, both slash (/) and backslash (\) are used as path separator character. In other environments, it is the forward slash (/).
Example 1. basename() example $path = "/home/httpd/html/index.php3"; $file = basename($path); // $file is set to "index.php3" |
See also: dirname()
chgrp -- ÆÄÀÏÀÇ groupÀ» ¹Ù²Û´Ù.
int chgrp(string filename, mixed group);
Attempts to change the group of the file filename to group. Only the superuser may change the group of a file arbitrarily; other users may change the group of a file to any group of which that user is a member.
Returns true on success; otherwise returns false.
On Windows, does nothing and returns true.
chmod -- ÆÄÀÏÀÇ mode¸¦ ¹Ù²Û´Ù.
int chmod(string filename, int mode);
Attempts to change the mode of the file specified by filename to that given in mode.
Note that mode is not automatically assumed to be an octal value. To ensure the expected operation, you need to prefix mode with a zero (0):
chmod( "/somedir/somefile", 755 ); // decimal; probably incorrect chmod( "/somedir/somefile", 0755 ); // octal; correct value of mode
Returns true on success and false otherwise.
chown -- ÆÄÀÏÀÇ owner¸¦ ¹Ù²Û´Ù.
int chown(string filename, mixed user);
Attempts to change the owner of the file filename to user user. Only the superuser may change the owner of a file.
Returns true on success; otherwise returns false.
NOTE: On Windows, does nothing and returns true.
See also chown() and chmod().
clearstatcache -- ÆÄÀÏÀÇ stat cache¸¦ ¹Ù²Û´Ù.
void clearstatcache(void);
Invoking the stat() or lstat() system call on most systems is quite expensive. Therefore, the result of the last call to any of the status functions (listed below) is stored for use on the next such call using the same filename. If you wish to force a new status check, for instance if the file is being checked many times and may change or disappear, use this function to clear the results of the last call from memory.
This value is only cached for the lifetime of a single request.
Affected functions include stat(), lstat(), file_exists(), is_writeable(), is_readable(), is_executable(), is_file(), is_dir(), is_link(), filectime(), fileatime(), filemtime(), fileinode(), filegroup(), fileowner(), filesize(), filetype(), and fileperms().
copy -- ÆÄÀÏÀ» º¹»çÇÑ´Ù.
int copy(string source, string dest);
Makes a copy of a file. Returns true if the copy succeeded, false otherwise.

See also: rename()
dirname -- pathÀÇ DirectoryºÎºÐÀ» µ¹·ÁÁØ´Ù.
string dirname(string path);
Given a string containing a path to a file, this function will return the name of the directory.
On Windows, both slash (/) and backslash (\) are used as path separator character. In other environments, it is the forward slash (/).
Example 1. dirname() example $path = "/etc/passwd"; $file = dirname($path); // $file is set to "/etc" |

fgets -- file pointer¿¡¼ ÇÑ ÁÙÀ» ÀÐ¾î ¿Â´Ù.
string fgets(int fp, int length);
Returns a string of up to length - 1 bytes read from the file pointed to by fp. Reading ends when length - 1 bytes have been read, on a newline, or on EOF (whichever comes first).
If an error occurs, returns false.
The file pointer must be valid, and must point to a file successfully opened by fopen(), popen(), or fsockopen().
See also fopen(), popen(), fgetc(), and fsockopen().
fgetss -- file pointer¿¡¼ ÇÑ ÁÙÀ» Àоî¿Í HTML tagµéÀ» stripÇÑ´Ù.

Returns false if an error occurs.
fopen -- ÆÄÀÏÀ̳ª URLÀ» ¿¬´Ù.
int fopen
(string filename, string mode);
If filename begins with "http://" (not case sensitive), an HTTP 1.0 connection is opened to the specified server and a file pointer is returned to the beginning of the text of the response.
Does not handle HTTP redirects, so you must include trailing slashes on directories.
If filename begins with "ftp://" (not case sensitive), an ftp connection to the specified server is opened and a pointer to the requested file is returned. If the server does not support passive mode ftp, this will fail. You can open files for either reading and writing via ftp (but not both simultaneously).
If filename begins with anything else, the file will be opened from the filesystem, and a file pointer to the file opened is returned.
If the open fails, the function returns false.
mode may be any of the following:
'r' - Open for reading only; place the file pointer at the beginning of the file.
'r+' - Open for reading and writing; place the file pointer at the beginning of the file.
'w' - Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero
length. If the file does not exist, attempt to create it.
'w+' - Open for reading and writing; place the file pointer at the beginning of the file and truncate the
file to zero length. If the file does not exist, attempt to create it.
'a' - Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt
to create it.
'a+' - Open for reading and writing; place the file pointer at the end of the file. If the file does not exist,
attempt to create it.
As well, mode may contain the letter 'b'. This is useful only on systems which differentiate between binary and text files (i.e., it's useless on Unix). If not needed, this will be ignored.
Example 1. fopen() example
|
If you are experiencing problems with reading and writing to files and you're using the server module version of PHP, remember to make sure that the files and directories you're using are accessible to the server process.
On the Windows platform, be careful to escape any backslashes used in the path to the file, or use forward slashes.
$fp = fopen("c:\\data\\info.txt", "r");
See also fclose(), fsockopen(), and popen().
fpassthru -- file pointer¿¡¼ºÎÅÍ ³²¾Æ ÀÖ´Â ¸ðµç µ¥ÀÌŸ¸¦ Ãâ·ÂÇÑ´Ù.
int fpassthru
(int fp);
Reads to EOF on the given file pointer and writes the results to standard output.
If an error occurs, fpassthru() returns false.
The file pointer must be valid, and must point to a file successfully opened by fopen(), popen(), or fsockopen(). The file is closed when fpassthru() is done reading it (leaving fp useless).
If you just want to dump the contents of a file to stdout you may want to use the readfile(), which saves you the fopen() call.
See also readfile(), fopen(), popen(), and fsockopen()
fputs -- file pointer¿¡ ¾´´Ù.
int fputs
(int fp, string str, int [length]);
fputs() is an alias to fwrite(), and is identical in every way. Note that the length parameter is optional and if not specified the entire string will be written.
fread -- ÆÄÀÏÀ» binary·Î Àоî¿Â´Ù.
string fread(int fp, int length);
fread() reads up to length bytes from the file pointer referenced by fp. Reading stops when length bytes have been read or EOF is reached, whichever comes first.
// get contents of a file into a string $filename = "/usr/local/something.txt"; $fd = fopen( $filename, "r" ); $contents = fread( $fd, filesize( $filename ) ); fclose( $fd );
See also fwrite(), fopen(), fsockopen(), popen(), fgets(), fgetss(), file(), and fpassthru().
fseek -- file pointer¸¦ ¿Å±ä´Ù.
int fseek(int fp, int offset);
Sets the file position indicator for the file referenced by fp to offset bytes into the file stream. Equivalent to calling (in C) fseek( fp, offset, SEEK_SET ).
Upon success, returns 0; otherwise, returns -1. Note that seeking past EOF is not considered an error.
May not be used on file pointers returned by fopen() if they use the "http://" or "ftp://" formats.
See also ftell() and rewind().
ftell -- file pointerÀÇ read/write À§Ä¡¸¦ ±¸ÇÑ´Ù.
int ftell(int fp);
Returns the position of the file pointer referenced by fp; i.e., its offset into the file stream.
If an error occurs, returns false.
The file pointer must be valid, and must point to a file successfully opened by fopen() or popen().
See also fopen(), popen(), fseek() and rewind().
fwrite -- ÆÄÀÏÀ» Binary·Î ¾´´Ù.
int fwrite(int fp, string string, int length);
fwrite() writes the contents of string to the file stream pointed to by fp. If the length argument is given, writing will stop after length bytes have been written or the end of string is reached, whichever comes first.
Note that if the length argument is given, then the magic_quotes_runtime configuration option will be ignored and no slashes will be stripped from string.
See also fread(), fopen(), fsockopen(), popen(), and fputs().
is_dir -- ÁöÁ¤µÈ ÆÄÀϸíÀÌ directoryÀΰ¡ ¾Ë·ÁÁØ´Ù.
bool is_dir(string filename);

link -- hard link¸¦ ¸¸µç´Ù.
int link(string target, string link);
Link() creates a hard link.
See also the symlink() to create soft links, and readlink() along with linkinfo().
linkinfo -- link¿¡ ´ëÇÑ Á¤º¸¸¦ ±¸ÇÑ´Ù.
int linkinfo(string path);
Linkinfo() returns the st_dev field of the UNIX C stat structure returned by the lstat system call. This function is used to verify if a link (pointed to by path) really exists (using the same method as the S_ISLNK macro defined in stat.h). Returns 0 or FALSE in case of error.
See also symlink(), link(), and readlink().
mkdir -- directory¸¦ ¸¸µç´Ù.
int mkdir
(string pathname, int mode);
Attempts to create the directory specified by pathname.
Note that you probably want to specify the mode as an octal number, which means it should have a leading zero.
mkdir("/path/to/my/dir", 0700);
Returns true on success and false on failure.
See also rmdir().
pclose -- process file pointer¸¦ ´Ý´Â´Ù.
int pclose(int fp);
Closes a file pointer to a pipe opened by popen().
The file pointer must be valid, and must have been returned by a successful call to popen().
Returns the termination status of the process that was run.
See also popen().
popen -- process file pointer¸¦ ¿¬´Ù.
int popen(string command, string mode);
Opens a pipe to a process executed by forking the command given by command.
Returns a file pointer identical to that returned by fopen(), except that it is unidirectional (may only be used for reading or writing) and must be closed with pclose(). This pointer may be used with fgets(), fgetss(), and fputs().
If an error occurs, returns false.
$fp = popen( "/bin/ls", "r" );
See also pclose().
readfile -- fileÀ» Àоî Ãâ·ÂÇÑ´Ù.
int readfile(string filename);
Reads a file and writes it to standard output.
Returns the number of bytes read from the file. If an error occurs, false is returned and unless the function was called as @readfile, an error message is printed.
If filename begins with "http://" (not case sensitive), an HTTP 1.0 connection is opened to the specified server and the text of the response is written to standard output.
Does not handle HTTP redirects, so you must include trailing slashes on directories.
If filename begins with "ftp://" (not case sensitive), an ftp connection to the specified server is opened and the requested file is written to standard output. If the server does not support passive mode ftp, this will fail.
If filename begins with neither of these strings, the file will be opened from the filesystem and its contents written to standard output.
See also fpassthru(), file(), fopen(), include(), require(), and virtual().
readlink -- symbolic linkÀÇ ´ë»óÀ» ¹ÝȯÇÑ´Ù.
int readlink(string path);
Readlink() does the same as the readlink C function and returns the contents of the symbolic link path or 0 in case of error.
See also symlink(), readlink() and linkinfo().
rename -- ÆÄÀϸíÀ» ¹Ù²Û´Ù.
int rename(string oldname, string newname);
Attempts to rename oldname to newname.
Returns true on success and false on failure.
rewind -- file pointer¸¦ ÆÄÀÏÀÇ Ã³À½ À§Ä¡·Î ¼³Á¤ÇÑ´Ù.
int rewind(int fp);
Sets the file position indicator for fp to the beginning of the file stream.
If an error occurs, returns 0.
The file pointer must be valid, and must point to a file successfully opened by fopen().
rmdir -- directory¸¦ Áö¿î´Ù.
int rmdir(string dirname);
Attempts to remove the directory named by pathname. The directory must be empty, and the relevant permissions must permit this.
If an error occurs, returns 0.
See also mkdir().
stat -- ÆÄÀÏÀÇ stat Á¤º¸¸¦ ±¸ÇÑ´Ù.
array stat(string filename);
Gathers the statistics of the file named by filename.
Returns an array with the statistics of the file with the following elements:
device
inode
number of links
user id of owner
group id owner
device type if inode device *
size in bytes
time of last access
time of last modification
time of last change
blocksize for filesystem I/O *
number of blocks allocated
* - only valid on systems supporting the st_blksize type--other systems (i.e. Windows) return -1
lstat -- ÆÄÀÏÀ̳ª symbolic linkÀÇ stat Á¤º¸¸¦ ±¸ÇÑ´Ù.
array lstat
(string filename);
Gathers the statistics of the file or symbolic link named by filename. This function is identical to the stat() function except that if the filename parameter is a symbolic link, the status of the symbolic link is returned, not the status of the file pointed to by the symbolic link.
Returns an array with the statistics of the file with the following elements:
device
inode
number of links
user id of owner
group id owner
device type if inode device *
size in bytes
time of last access
time of last modification
time of last change
blocksize for filesystem I/O *
number of blocks allocated
* - only valid on systems supporting the st_blksize type--other systems (i.e. Windows) return -1
symlink -- symbolic link¸¦ ¸¸µç´Ù.
int symlink(string target, string link);
symlink() creates a symbolic link from the existing target with the specified name link.
See also link() to create hard links, and readlink() along with linkinfo().
tempnam -- À¯ÀÏÇÑ ÆÄÀϸíÀ» ¸¸µç´Ù.
string tempnam(string dir, string prefix);
Creates a unique temporary filename in the specified directory. If the directory does not exist, tempnam() may generate a filename in the system's temporary directory.
Returns the new temporary filename, or the null string on failure.
Example 1. tempnam() example $tmpfname = tempnam( "/tmp", "FOO" ); |
touch -- ÆÄÀÏÀÇ ¼öÁ¤ ½Ã°¢À» ¼³Á¤ÇÑ´Ù.
int touch(string filename, int time);
Attempts to set the modification time of the file named by filename to the value given by time. If the option time is not given, uses the present time.
If the file does not exist, it is created.
Returns true on success and false otherwise.
umask -- ÇöÀçÀÇ umask¸¦ º¯°æÇÑ´Ù.
int umask(int mask);
Umask() sets PHP's umask to mask & 0777 and returns the old umask. When PHP is being used as a server module, the umask is restored when each request is finished.
Umask() without arguments simply returns the current umask.
unlink -- ÆÄÀÏÀ» Áö¿î´Ù.
int unlink(string filename);
Deletes filename. Similar to the Unix C unlink() function.
Returns 0 or FALSE on an error.
See also rmdir() for removing directories.
ÀÌ ÇÔ¼öµéÀº HTTP protocol leve¿¡¼ µ¥ÀÌŸ¸¦ remote browser·Î Á÷Á¢ Àü¼ÛÇÒ ¼ö ÀÖµµ·Ï ÇØ ÁØ´Ù.
header -- HTTP Çì´õ µ¥ÀÌŸ¸¦ Àû¾îÁØ ±×´ë·Î º¸³½´Ù.
int header
(string string);
The Header() function is used at the top of an HTML file to send raw HTTP header strings. See the HTTP 1.1 Specification for more information on raw http headers. Note: Remember that the Header() function must be called before any actual output is sent either by normal HTML tags or from PHP. It is a very common error to read code with include() or with auto_prepend and have spaces or empty lines in this code that force output before header() is called.
Header("Location: http://www.php.net"); /* Redirect browser to PHP web site */exit; /* Make sure that code below does not get executed when we redirect. */
PHP scripts often generate dynamic HTML that must not be cached by the client browser or any proxy caches between the server and the client browser. Many proxies and clients can be forced to disable caching with
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the pastheader("Last-Modified: " . gmdate("D, d M Y H:i:s") . "GMT"); // always modifiedheader("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1header("Pragma: no-cache"); // HTTP/1.0
setcookie -- cookie¸¦ ¼³Á¤Çϵµ·Ï µ¥ÀÌŸ¸¦ ºê¶ó¿ìÀú·Î º¸³½´Ù.
int setcookie(string name, string value, int expire, string path, string domain, int secure);
SetCookie() defines a cookie to be sent along with the rest of the header information. All the arguments except the name argument are optional. If only the name argument is present, the cookie by that name will be deleted from the remote client. You may also replace any argument with an empty string ("") in order to skip that argument. The expire and secure arguments are integers and cannot be skipped with an empty string. Use a zero (0) instead. The expire argument is a regular Unix time integer as returned by the time() or mktime() functions. The secure indicates that the cookie should only be transmitted over a secure HTTPS connection. Some examples follow:
Example 1. SetCookie examples SetCookie("TestCookie","Test Value"); SetCookie("TestCookie",$value,time()+3600); /* expire in 1 hour */ SetCookie("TestCookie",$value,time()+3600,"/~rasmus/",".utoronto.ca",1); |
Note that the value portion of the cookie will automatically be urlencoded when you send the cookie, and when it is received, it is automatically decoded and assigned to a variable by the same name as the cookie name. ie. to see the contents of our test cookie in a script, simply do:
echo $TestCookie;
For more information on cookies, see Netscape's cookie specification at http://www.netscape.com/newsref/std/cookie_spec.html.
Microsoft Internet Explorer 4 with Service Pack 1 applied does not correctly deal with cookies that have their path parameter set.

int hw_gettext
(int connection, int objectID, int rootID);
Returns the document with object ID objectID. If the document has anchors which can be inserted, they will be inserted already. The optional parameter rootID determines how links are inserted into the document. The default is 0 and will result in links that are constructed from the name of the link's destination object. This is useful for web applications. If a link points to an object with name 'internet_movie' the HTML link will be <A HREF="/internet_movie">. The actual location of the source and destination object in the document hierachy is disregarded. You will have to set up your web browser, to rewrite that URL to for example '/my_script.php3/internet_movie'. 'my_script.php3' will have to evaluate $PATH_INFO and retrieve the document.
If rootID is unequal to 0 the link is constructed from all the names starting at the object with the id rootID separated by a slash relative to the current object. If for example the above document 'internet_movie' is located at 'a-b-c-internet_movie' with '-' being the seperator between hierachy levels and the source document is located at 'a-b-d-source' the resulting HTML link would be: <A HREF="../c/internet_movie">. This is useful if you want to download the whole server content onto disk and map the document hierachy onto the file system.
This function will only work for pure text documents. It will not open a special data connection and therefore blocks the control connection during the transfer.

This function calculates and returns the bounding box in pixels a TrueType text.
text The string to be measured.
size The font size.
fontfile The name of the TrueType font file. (Can also be an URL.)
angle Angle in degrees in which text will be measured.

lower right corner, Y position |
4 |
upper right corner, X position |
5 |
upper right corner, Y position |
6 |
upper left corner, X position |
7 |
upper left corner, Y position |
The points are relative to the text regardless of the angle, so "upper left" means in the top left-hand corner seeing the text horizontallty.
This function requires both the GD library and the Freetype library.
See also ImageTTFText().
ImageTTFText -- TrueType ÆùÆ®¸¦ »ç¿ëÇÏ¿© ¹®ÀÚ¿À» ¾´´Ù.
array ImageTTFText
(int im, int size, int angle, int x, int y, int col, string fontfile, string text);
ImageTTFText draws the string text in the image identified by im, starting at coordinates x,y (top left is 0,0), at an angle of angle in color col, using the TrueType font file identified by fontfile.
The coordinates given by x,y will define the basepoint of the first character (roughly the lower-left corner of the character). This is different from the ImageString(), where x,y define the upper-right corner of the first character.
angle is in degrees, with 0 degrees being left-to-right reading text (3 o'clock direction), and higher values representing a counter-clockwise rotation. (i.e., a value of 90 would result in bottom-to-top reading text).
fontfile is the path to the TrueType font you wish to use.
text is the text string which may include UTF-8 character sequences (of the form: { ) to access characters in a font beyond the first 255.
col is the color index. Using the negative of a color index has the effect of turning off antialiasing.
ImageTTFText() returns an array with 8 elements representing four points making the bounding box of the text. The order of the points is upper left, upper right, lower right, lower left. The points are relative to the text regardless of the angle, so "upper left" means in the top left-hand corner when you see the text horizontallty.
This example script will produce a black GIF 400x30 pixels, with the words "Testing..." in white in the font Arial.

error_log -- ¿¡·¯ ¸Þ¼¼Áö¸¦ ÁöÁ¤ÇÑ °÷¿¡ º¸³½´Ù.
int error_log
(string message, int message_type, string [destination], string [extra_headers]);
Sends an error message to the web server's error log, a TCP port or to a file. The first parameter, message, is the error message that should be logged. The second parameter, message_type says where the message should go:
Table 1. error_log() log types
0 |
message is sent to PHP's system logger, using the Operating System's system logging mechanism or a file, depending on what the error_log configuration directive is set to. |
1 |
message is sent by email to the address in the destination parameter. This is the only message type where the fourth parameter, extra_headers is used. This message type uses the same internal function as Mail() does. |
2 |
message is sent through the PHP debugging connection. This option is only available if remote debugging has been enabled. In this case, the destination parameter specifies the host name or IP address and optionally, port number, of the socket receiving the debug information. |
3 |
message is appended to the file destination. |

ifx_connect -- Informix ¼¹ö connectionÀ» ¿¬´Ù.
int ifx_connect
(string [database] , string [userid] , string [password] );
Returns an connection identifier on success, or FALSE on error.
ifx_connect() establishes a connection to an Informix server. All of the arguments are optional, and if they're missing, defaults are taken from values supplied in php3.ini (ifx.default_host for the host (Informix libraries will use $INFORMIXSERVER environment value if not defined), ifx.default_user for user, ifx.default_password for the password (none if not defined).
In case a second call is made to ifx_connect() with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned.
The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling ifx_close().
See also ifx_pconnect(), and ifx_close().
Example 1. Connect to a Informix database
|
ifx_pconnect -- ¿µ±¸ÀûÀÎ(persistent) Informix ¼¹ö connectionÀ» ¿¬´Ù.
int ifx_pconnect
(string [database] , string [userid] , string [password] );
Returns: A positive Informix persistent link identifier on success, or false on error
ifx_pconnect() acts very much like ifx_connect() with two major differences.
This function behaves exactly like ifx_connect() when PHP is not running as an Apache module. First, when connecting, the function would first try to find a (persistent) link that's already open with the same host, username and password. If one is found, an identifier for it will be returned instead of opening a new connection.
Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (ifx_close() will not close links established by ifx_pconnect()).
This type of links is therefore called 'persistent'.
See also: ifx_connect().
ifx_close -- Informix connectionÀ» ´Ý´Â´Ù.
int ifx_close
(int [link_identifier] );
Returns: always true.
ifx_close() closes the link to an Informix database that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.
Note that this isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
ifx_close() will not close persistent links generated by ifx_pconnect().
See also: ifx_connect(), and ifx_pconnect().
Example 1. Closing a Informix connection

ifx_query -- Informix ÁúÀǸ¦ Àü¼ÛÇÑ´Ù.
int ifx_query
(string query, int [link_identifier] , int [cursor_type] , mixed [blobidarray] );
Returns: A positive Informix result identifier on success, or false on error.
An integer "result_id" used by other functions to retrieve the query results. Sets "affected_rows" for retrieval by the ifx_affected_rows() function.
ifx_query() sends a query to the currently active database on the server that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed. If no link is open, the function tries to establish a link as if ifx_connect() was called, and use it.
Executes query on connection conn_id. For "select-type" queries a cursor is declared and opened. The optional cursor_type parameter allows you to make this a "scroll" and/or "hold" cursor. It's a mask and can be either IFX_SCROLL, IFX_HOLD, or both or'ed together. Non-select queries are "execute immediate".
For either query type the number of (estimated or real) affected rows is saved for retrieval by ifx_affected_rows().
If you have BLOB (BYTE or TEXT) columns in an update query, you can add a blobidarray parameter containing the corresponding "blob ids", and you should replace those columns with a "?" in the query text.
If the contents of the TEXT (or BYTE) column allow it, you can also use "ifx_textasvarchar(1)" and "ifx_byteasvarchar(1)". This allows you to treat TEXT (or BYTE) columns just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to bother with blob id's.
With ifx_textasvarchar(0) or ifx_byteasvarchar(0) (the default situation), select queries will return BLOB columns as blob id's (integer value). You can get the value of the blob as a string or file with the blob functions (see below).
See also: ifx_connect().

ifx_prepare -- ½ÇÇàÀ» À§ÇÑ SQL¹®À» ÁغñÇÑ´Ù.
int ifx_prepare
(string query, int conn_id, int [cursor_def], mixed blobidarray);
Returns a integer result_id for use by ifx_do(). Sets affected_rows for retrieval by the ifx_affected_rows() function.
Prepares query on connection conn_id. For "select-type" queries a cursor is declared and opened. The optional cursor_type parameter allows you to make this a "scroll" and/or "hold" cursor. It's a mask and can be either IFX_SCROLL, IFX_HOLD, or both or'ed together.
For either query type the estimated number of affected rows is saved for retrieval by ifx_affected_rows().
If you have BLOB (BYTE or TEXT) columns in the query, you can add a blobidarray parameter containing the corresponding "blob ids", and you should replace those columns with a "?" in the query text.
If the contents of the TEXT (or BYTE) column allow it, you can also use "ifx_textasvarchar(1)" and "ifx_byteasvarchar(1)". This allows you to treat TEXT (or BYTE) columns just as if they were ordinary (but long) VARCHAR columns for select queries, and you don't need to bother with blob id's.
With ifx_textasvarchar(0) or ifx_byteasvarchar(0) (the default situation), select queries will return BLOB columns as blob id's (integer value). You can get the value of the blob as a string or file with the blob functions (see below).
See also: ifx_do().
ifx_do -- ÀÌÀü¿¡ ÁغñµÈ SQL¹®À» ½ÇÇàÇÑ´Ù.
int ifx_do
(int result_id);
Returns TRUE on success, FALSE on error.
Executes a previously prepared query or opens a cursor for it.
Does NOT free result_id on error.
Also sets the real number of ifx_affected_rows() for non-select statements for retrieval by ifx_affected_rows()
See also: ifx_prepare(). There is a example.
ifx_error -- ¸¶Áö¸·¿¡ ¼öÇàÇÑ Informix ¸í·ÉÀÇ ¿¡·¯ Äڵ带 µ¹·ÁÁØ´Ù.
string ifx_error
(void);
The Informix error codes (SQLSTATE & SQLCODE) formatted as follows :
x [SQLSTATE = aa bbb SQLCODE=cccc]
where x = space : no error
E : error
N : no more data
W : warning
? : undefined
If the "x" character is anything other than space, SQLSTATE and SQLCODE describe the error in more detail.
See the Informix manual for the description of SQLSTATE and SQLCODE
Returns in a string one character describing the general results of a statement and both SQLSTATE and SQLCODE associated with the most recent SQL statement executed. The format of the string is "(char) [SQLSTATE=(two digits) (three digits) SQLCODE=(one digit)]". The first character can be ' ' (space) (success), 'W' (the statement caused some warning), 'E' (an error happened when executing the statement) or 'N' (the statement didn't return any data).

ifx_errormsg -- ¸¶Áö¸·¿¡ ¼öÇàÇÑ Informix ¸í·ÉÀÇ ¿¡·¯ ¸Þ¼¼Áö¸¦ µ¹·ÁÁØ´Ù.
string ifx_errormsg

printf("%s\n<br>", ifx_errormsg(-201));
ifx_affected_rows -- ÁúÀÇ¿¡ ¿µÇâÀ» ¹Þ´Â rowÀÇ °³¼ö¸¦ ±¸ÇÑ´Ù.
int ifx_affected_rows
(int result_id);
result_id is a valid result id returned by ifx_query() or ifx_prepare().
Returns the number of rows affected by a query associated with result_id.
For inserts, updates and deletes the number is the real number (sqlerrd[2]) of affected rows. For selects it is an estimate (sqlerrd[0]). Don't rely on it.
Useful after ifx_prepare() to limit queries to reasonable result sets.
See also: ifx_num_rows()

ifx_fetch_row -- row¸¦ ¹è¿(enumerated array)·Î °¡Á®¿Â´Ù.
array ifx_fetch_row
(int result_id, mixed [position] );
Returns an associative array that corresponds to the fetched row, or false if there are no more rows.
Blob columns are returned as integer blob id values for use in ifx_get_blob() unless you have used ifx_textasvarchar(1) or ifx_byteasvarchar(1), in which case blobs are returned as string values. Returns FALSE on error
result_id is a valid resultid returned by ifx_query() or ifx_prepare() (select type queries only!).
[position] is an optional parameter for a "fetch" operation on "scroll" cursors: "NEXT", "PREVIOUS", "CURRENT", "FIRST", "LAST" or a number. If you specify a number, an "absolute" row fetch is executed. This parameter is optional, and only valid for scrollcursors.
ifx_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.
Subsequent call to ifx_fetch_row() would return the next row in the result set, or false if there are no more rows.

ldap_add -- LDAP directory¿¡ entry¸¦ Ãß°¡ÇÑ´Ù.
int ldap_add
(int link_identifier, string dn, array entry);
returns true on success and false on error.
The ldap_add() function is used to add entries in the LDAP directory. The DN of the entry to be added is specified by dn. Array entry specifies the information about the entry. The values in the entries are indexed by individual attributes. In case of multiple values for an attribute, they are indexed using integers starting with 0.
entry["attribute1"] = value
entry["attribute2"][0] = value1
entry["attribute2"][1] = value2
Example 1. Complete example with authenticated bind
|
ldap_bind -- LDAP directory¿¡ bind ÇÑ´Ù.
int ldap_bind(int link_identifier, string bind_rdn, string bind_password);
Binds to the LDAP directory with specified RDN and password. Returns true on success and false on error.
ldap_bind() does a bind operation on the directory. bind_rdn and bind_password are optional. If not specified, anonymous bind is attempted.
ldap_close -- LDAP server¿ÍÀÇ ¿¬°áÀ» ´Ý´Â´Ù.
int ldap_close
(int link_identifier);
Returns true on success, false on error.
ldap_close() closes the link to the LDAP server that's associated with the specified link_identifier.
This call is internally identical to ldap_unbind(). The LDAP API uses the call ldap_unbind(), so perhaps you should use this in preference to ldap_close().
ldap_connect -- LDAP server¿Í ¿¬°áÇÑ´Ù.
int ldap_connect(string hostname, int port);
Returns a positive LDAP link identifier on success, or false on error.
ldap_connect() establishes a connection to a LDAP server on a specified hostname and port. Both the arguments are optional. If no arguments are specified then the link identifier of the already opened link will be returned. If only hostname is specified, then the port defaults to 389.
ldap_count_entries -- Ž»ö ¹üÀ§ ¾È¿¡ ÀÖ´Â entryÀÇ °³¼ö
int ldap_count_entries(int link_identifier, int result_identifier);
Returns number of entries in the result or false on error.
ldap_count_entries() returns the number of entries stored in the result of previous search operations. result_identifier identifies the internal ldap result.
ldap_delete -- directory¾ÈÀÇ ÇÑ entry¸¦ »èÁ¦ÇÑ´Ù..
int ldap_delete(int link_identifier, string dn);
Returns true on success and false on error.
ldap_delete() function delete a particular entry in LDAP directory specified by dn.
ldap_dn2ufn -- DNÀ» User Friendly Naming Çü½ÄÀ¸·Î º¯È¯ÇÑ´Ù.
string ldap_dn2ufn(string dn);
ldap_dn2ufn() function is used to turn a DN into a more user-friendly form, stripping off type names.
ldap_explode_dn -- DNÀ» ±×°ÍÀÇ ±¸¼º ºÎºÐÀ¸·Î ³ª´«´Ù.
string ldap_explode_dn(string dn, int with_attrib);
ldap_explode_dn() function is used to split the a DN returned by ldap_get_dn() and breaks it up into its component parts. Each part is known as Relative Distinguished Name, or RDN. ldap_explode_dn() returns an array of all those components. with_attrib is used to request if the RDNs are returned with only values or their attributes as well. To get RDNs with the attributes (i.e. in attribute=value format) set with_attrib to 1 and to get only values set it to 0.
ldap_first_attribute -- ù¹ø° ¼Ó¼ºÀ» ¹ÝȯÇÑ´Ù.
string ldap_first_attribute(int link_identifier, int result_entry_identifier, int ber_identifier);
Returns the first attribute in the entry on success and false on error.
Similar to reading entries, attributes are also read one by one from a particular entry. ldap_first_attribute() returns the first attribute in the entry pointed by the entry identifier. Remaining attributes are retrieved by calling ldap_next_attribute() successively. ber_identifier is the identifier to internal memory location pointer. It is passed by reference. The same ber_identifier is passed to the ldap_next_attribute() function, which modifies that pointer.
see also ldap_get_attributes()
ldap_first_entry -- ù¹ø° result id¸¦ ¹ÝȯÇÑ´Ù.
int ldap_first_entry
(int link_identifier, int result_identifier);
Returns the result entry identifier for the first entry on success and false on error.
Entries in the LDAP result are read sequentially using the ldap_first_entry() and ldap_next_entry() functions. ldap_first_entry() returns the entry identifier for first entry in the result. This entry identifier is then supplied to lap_next_entry() routine to get successive entries from the result.
see also ldap_get_entries().
ldap_free_result -- result memory¸¦ Ç®¾îÁØ´Ù.
int ldap_free_result
(int result_identifier);
Returns true on success and false on error.
ldap_free_result() frees up the memory allocated internally to store the result and pointed by the result_identifier. All result memory will be automatically freed when the script terminates.
Typically all the memory allocated for the ldap result gets freed at the end of the script. In case the script is making successive searches which return large result sets, ldap_free_result() could be called to keep the runtime memory usage by the script low.
ldap_get_attributes -- search result entry·ÎºÎÅÍ ¼Ó¼ºÀ» ±¸ÇÑ´Ù.
array ldap_get_attributes
(int link_identifier, int result_entry_identifier);
Returns a comlete entry information in a multi-dimensional array on success and false on error.
ldap_get_attributes() function is used to simplify reading the attributes and values from an entry in the search result. The return value is a multi-dimensional array of attributes and values.
Having located a specific entry in the directory, you can find out what information is held for that entry by using this call. You would use this call for an application which "browses" directory entries and/or where you do not know the structure of the directory entries. In many applications you will be searching for a specific attribute such as an email address or a surname, and won't care what other data is held.
return_value["count"] = number of attributes in the entry
return_value[0] = first attribute
return_value[n] = nth attribute
return_value["attribute"]["count"] = number of values for attribute
return_value["attribute"][0] = first value of the attribute
return_value["attribute"][i] = ith value of the attribute
Example 1. Show the list of attributes held for a particular directory entry

see also ldap_first_attribute() and ldap_next_attribute()
ldap_get_dn -- result entryÀÇ DNÀ» ±¸ÇÑ´Ù.
string ldap_get_dn(int link_identifier, int result_entry_identifier);
Returns the DN of the result entry and false on error.
ldap_get_dn() function is used to find out the DN of an entry in the result.
ldap_get_entries -- ¸ðµç result entryµéÀ» ±¸ÇÑ´Ù.
array ldap_get_entries
(int link_identifier, int result_identifier);
Returns a complete result information in a multi-dimenasional array on success and false on error.
ldap_get_entries() function is used to simplify reading multiple entries from the result and then reading the attributes and multiple values. The entire information is returned by one function call in a multi-dimensional array. The structure of the array is as follows.
The attribute index is converted to lowercase. (Attributes are case-insensitive for directory servers, but not when used as array indices)
return_value["count"] = number of entries in the result
return_value[0] : refers to the details of first entry
return_value[i]["dn"] = DN of the ith entry in the result
return_value[i]["count"] = number of attributes in ith entry
return_value[i][j] = jth attribute in the ith entry in the result
return_value[i]["attribute"]["count"] = number of values for attribute in ith entry
return_value[i]["attribute"][j] = jth value of attribute in ith entry
see also ldap_first_entry() and ldap_next_entry()
ldap_get_values -- result entry·Î ºÎÅÍ ¸ðµç °ªÀ» ±¸ÇÑ´Ù.
array ldap_get_values
(int link_identifier, int result_entry_identifier, string attribute);
Returns an array of values for the attribute on success and false on error.
ldap_get_values() function is used to read all the values of the attribute in the entry in the result. entry is specified by the result_entry_identifier. The number of values can be found by indexing "count" in the resultant array. Individual values are accessed by integer index in the array. The first index is 0.
This call needs a result_entry_identifier, so needs to be preceded by one of the ldap search calls and one of the calls to get an individual entry.
You application will either be hard coded to look for certain attributes (such as "surname" or "mail") or you will have to use the ldap_get_attributes() call to work out what attributes exist for a given entry.
LDAP allows more than one entry for an attribute, so it can, for example, store a number of email addresses for one person's directory entry all labeled with the attribute "mail"
return_value["count"] = number of values for attribute
return_value[0] = first value of attribute
return_value[i] = ith value of attribute
Example 1. List all values of the "mail" attribute for a directory entry
|
ldap_list -- Single-level °Ë»ö (search)
int ldap_list
(int link_identifier, string base_dn, string filter);
Returns a search result identifier or false on error.
ldap_list() performs the search for a specified filter on the directory with the scope LDAP_SCOPE_ONELEVEL.
LDAP_SCOPE_ONELEVEL means that the search should only return information that is at the level immediately below the base dn given in the call. (Equivalent to typing "ls" and getting a list of files and folders in the current working directory.)
This call takes an optional fourth parameter which is an array of the attributes required. See ldap_search() notes.
Example 1. Produce a list of all organizational units of an organization
|
ldap_modify -- LDAP entry¸¦ ¼öÁ¤ÇÑ´Ù.
int ldap_modify(int link_identifier, string dn, array entry);
Returns true on success and false on error.
ldap_modify() function is used to modify the existing entries in the LDAP directory. The structure of the entry is same as in ldap_add().
ldap_next_attribute -- resultÀÇ ´ÙÀ½ ¼Ó¼ºÀ» ±¸ÇÑ´Ù.
string ldap_next_attribute
(int link_identifier, int result_entry_identifier, int ber_identifier);
Returns the next attribute in an entry on success and false on error.
ldap_next_attribute() is called to retrieve the attributes in an entry. The internal state of the pointer is maintained by the ber_identifier. It is passed by reference to the function. The first call to ldap_next_attribute() is made with the result_entry_identifier returned from ldap_first_attribute().
see also ldap_get_attributes()
ldap_next_entry -- ´ÙÀ½ result entry¸¦ ±¸ÇÑ´Ù.
int ldap_next_entry
(int link_identifier, int result_entry_identifier);
Returns entry identifier for the next entry in the result whose entries are being read starting with ldap_first_entry(). If there are no more entries in the result then it returns false.
ldap_next_entry() function is used to retrieve the entries stored in the result. Successive calls to the ldap_next_entry() return entries one by one till there are no more entries. The first call to ldap_next_entry() is made after the call to ldap_first_entry() with the result_identifier as returned from the ldap_first_entry().
see also ldap_get_entries()
ldap_read -- entry¸¦ Àд´Ù.
int ldap_read
(int link_identifier, string base_dn, string filter, array [attributes]);
Returns a search result identifier or false on error.
ldap_read() performs the search for a specified filter on the directory with the scope LDAP_SCOPE_BASE. So it is equivalent to reading an entry from the directory.
An empty filter is not allowed. If you want to retrieve absolutely all information for this entry, use a filter of "objectClass=*". If you know which entry types are used on the directory server, you might use an appropriate filter such as "objectClass=inetOrgPerson".
This call takes an optional fourth parameter which is an array of the attributes required. See ldap_search() notes.
ldap_search -- LDAP tree¸¦ °Ë»öÇÑ´Ù.
int ldap_search
(int link_identifier, string base_dn, string filter, array [attributes]);
Returns a search result identifier or false on error.
ldap_search() performs the search for a specified filter on the directory with the scope of LDAP_SCOPE_SUBTREE. This is equivalent to searching the entire directory. base_dn specifies the base DN for the directory.
There is a optional fourth parameter, that can be added to restrict the attributes and values returned by the server to just those required. This is much more efficient than the default action (which is to return all attributes and their associated values). The use of the fourth parameter should therefore be considered good practice.
The fourth parameter is a standard PHP string array of the required attributes, eg array("mail","sn","cn") Note that the "dn" is always returned irrespective of which attributes types are requested.
Note too that some directory server hosts will be configured to return no more than a preset number of entries. If this occurs, the server will indicate that it has only returned a partial results set.
The search filter can be simple or advanced, using boolean operators in the format described in the LDAP doumentation (see the Netscape Directory SDK for full information on filters).
The example below retrieves the organizational unit, surname, given name and email address for all people in "My Company" where the surname or given name contains the substring $person. This example uses a boolean filter to tell the server to look for information in more than one attribute.
Example 1. LDAP search
|
When you perform a search, and too much data comes back (alot of entries) you will get a warning, and ldap_get_entries() will fail. The trick here is to turn off the warnings, then check the return value.
$normerr = error_reporting ();
error_reporting (0); // turn off warnings!
$sr = ldap_search ($ds, $dn, $searchfor);
$normerr = error_reporting ($normerr);
if (!$sr) {
print "too many entries!";
} else .....
You could try narrowing the scope, by adding an extra filter eg. (cn=a*), but It would be nicer to be able to grab the results in bits (eg. 1-100, 101-200...).
ldap_unbind -- LDAP directory·ÎºÎÅÍ unbindÇÑ´Ù.
int ldap_unbind(int link_identifier);

bool mail
(string to, string subject, string message, string additional_headers);
Mail() automatically mails the message specified in message to the receiver specified in to. Multiple recipients can be specified by putting a space between each address in to.
Example 1. Sending mail.

mixed min(mixed arg1, mixed arg2, mixed argn);
min() returns the numerically lowest of the parameter values.
If the first parameter is an array, min() returns the lowest value in that array. If the first parameter is an integer, string or double, you need at least two parameters and min() returns the lowest of these values. You can compare an unlimited number of values.

mt_rand -- ´õ ÁÁÀº ³¼ö °ªÀ» ¸¸µé¾î ³½´Ù.
int mt_rand
([int min], [int max]);
Many random number generators of older libcs have dubious or unknown characteristics and are slow. By default, PHP uses the libc random number generator with the rand() function. mt_rand() function is a drop-in replacement for this. It uses a random number generator with known characteristics, the Mersenne Twister, which will produce random numbers that should be suitable for cryptographic purposes and is four times faster than what the average libc provides. The Homepage of the Mersenne Twister can be found at http://www.math.keio.ac.jp/~matumoto/emt.html, and an optimized version of the MT source is available from http://www.scp.syr.edu/~marc/hawk/twister.html.
If called without the optional min,max arguments mt_rand() returns a pseudo-random value between 0 and RAND_MAX. If you want a random number between 5 and 15 (inclusive), for example, use mt_rand(5,15).
Remember to seed the random number generator before use with mt_srand().
See also mt_srand(), mt_getrandmax(), srand(), rand() and getrandmax().

string number_format
(float number, int decimals, string dec_point, string thousands_sep);
number_format() returns a formatted version of number. This function accepts either one, two or four parameters (not three):
If only one parameter is given, number will be formatted without decimals, but with a comma (",") between every group of thousands.
If two parameters are given, number will be formatted with decimals decimals with a dot (".") in front, and a comma (",") between every group of thousands.
If all four parameters are given, number will be formatted with decimals decimals, dec_point instead of a dot (".") before the decimals and thousands_sep instead of a comma (",") between every group of thousands.
OctDec -- 8Áø¼ö¸¦ 10Áø¼ö·Î
int octdec(string octal_string);
Returns the decimal equivalent of the hexadecimal number represented by the hex_string argument. OctDec converts an octal string to a decimal number. The largest number that can be converted is 17777777777 or 2147483647 in decimal.

eval -- PHP Äڵ带 °¡Áø ¹®ÀÚ¿À» ½ÇÇàÇÑ´Ù.
void eval
(string code_str);
eval() evaluates the string given in code_str as PHP code. Among other things, this can be useful for storing code in a database text field for later execution.
There are some factors to keep in mind when using eval(). Remember that the string passed must be valid PHP code, including things like terminating statements with a semicolon so the parser doesn't die on the line after the eval(), and properly escaping things in code_str.
Also remember that variables given values under eval() will retain these values in the main script afterwards.
Example 1. eval() example - simple text merge

The above example will show:
This is a $string with my $name in it.This is a cup with my coffee in it.
extract -- ÇÑ ¹è¿¿¡¼ symbol table·Î º¯¼öµéÀ» ÀÐ¾î µéÀδÙ.
void extract
(array var_array, int extract_type, string [var_array]);
This function is used to import variables from an array into the current symbol table. It takes associative array var_array and treats keys as variable names and values as variable values. For each key/value pair it will create a variable in the current symbol table, subject to extract_type and prefix parameters.
extract() checks for colissions with existing variables. The way collisions are treated is determined by extract_type. It can be one of the following values:
If there is a collision, overwrite the existing variable.
If there is a collision, don't overwrite the existing variable.
If there is a collision, prefix the new variable with prefix.
Prefix all variables with prefix.
Note that prefix is only required if extract_type is EXTR_PREFIX_SAME or EXTR_PREFIX_ALL.
extract() checks each key to see if it constitues a valid variable name, and if it does only then does it proceed to import it.
A possible use for extract is to import into symbol table variables contained in an associative array returned by wddx_deserialize().
Example 1. extract example
|
The above example will produce:
blue, large, sphere, medium
The $size wasn't overwritten, becaus we specified EXTR_PREFIX_SAME, which resulted in $wddx_size being created. If EXTR_SKIP was specified, then $wddx_size wouldn't even have been created. EXTR_OVERWRITE would have cause $size to have value "medium", and EXTR_PREFIX_ALL would result in new variables being named $wddx_color, $wddx_size, and $wddx_shape.
die -- ¸Þ½ÃÁö¸¦ Ãâ·ÂÇÏ°í ÇöÀç ½ºÅ©¸³Æ®ÀÇ ½ÇÇàÀ» Áß´ÜÇÑ´Ù.

int ignore_user_abort
(int [setting]);
This function sets whether a client disconnect should cause a script to be aborted. It will return the previous setting and can be called without an argument to not change the current setting and only return the current setting. See the Connection Handling section in the Features chapter for a complete description of connection handling in PHP.
iptcparse -- binary IPTC http://www.xe.net/iptc/ blockÀ» ÇϳªÀÇ ÅÃÀ¸·Î parseÇÑ´Ù.
array iptcparse
(string iptcblock);
This function parses a binary IPTC block into its single tags. It returns an array using the tagmarker as an index and the value as the value. See GetImageSize() for a sample.
leak -- ¸Þ¸ð¸®¸¦ ´©¼³(Leak) ÇÑ´Ù.
void leak
(int bytes);
Leak() leaks the specified amount of memory.
This is useful when debugging the memory manager, which automatically cleans up "leaked" memory when each request is completed.
pack -- data¸¦ binary ¹®ÀÚ¿·Î packÇÑ´Ù.
string pack
(string format, mixed [args]...);
Pack given arguments into binary string according to format. Returns binary string containing data.
The idea to this function was taken from Perl and all formatting codes work the same as there. The format string consists of format codes followed by an optional repeater argument. The repeater argument can be either an integer value or * for repeating to the end of the input data. For a, A, h, H the repeat count specifies how many characters of one data argument are taken, for @ it is the absolute position where to put the next data, for everything else the repeat count specifies how many data arguments are consumed and packed into the resulting binary string. Currently implemented are
a NUL-padded string
A SPACE-padded string
h Hex string, low nibble first
H Hex string, high nibble first
c signed char
C unsigned char
s signed short (always 16 bit, machine byte order)
S unsigned short (always 16 bit, machine byte order)
n unsigned short (always 16 bit, big endian byte order)
v unsigned short (always 16 bit, little endian byte order)
i signed integer (machine dependant size and byte order)
I unsigned integer (machine dependant size and byte order)
l signed long (always 32 bit, machine byte order)
L unsigned long (always 32 bit, machine byte order)
N unsigned long (always 32 bit, big endian byte order)
V unsigned long (always 32 bit, little endian byte order)
f float (machine dependent size and representation)
d double (machine dependent size and representation)
x NUL byte
X Back up one byte
@ NUL-fill to absolute position
Example 1. pack format string
The resulting binary string will be 6 bytes long and contain the byte sequence 0x12, 0x34, 0x78, 0x56, 0x41, 0x42. |
Note that the distinction between signed and unsigned values only affects the function unpack(), where as function pack() gives the same result for signed and unsigned format codes.
Also note that PHP internally stores integral values as signed values of a machine dependant size. If you give it an unsigned integral value too large to be stored that way it is converted to a double which often yields an undesired result.
register_shutdown_function -- ½ºÅ©¸³Æ®°¡ Á¾·áµÉ ¶§ ½ÇÇàµÉ ÇÔ¼ö¸¦ ¼³Á¤ÇÑ´Ù.
int register_shutdown_function
(string func);
Registers the function named by func to be executed when script processing is complete.
serialize -- ¾î¶² ÇüÅÂÀÇ °ªÀÌ¶óµµ ÀúÀå °¡´ÉÇÑ ÇüÅÂÀÇ ¹®ÀÚ¿·Î ¸¸µé¾î ÁØ´Ù.
string serialize
(mixed value);
serialize() returns a string containing a byte-stream representation of value that can be stored anywhere.
This is useful for storing or passing PHP values around without losing their type and structure.
To make the serialized string into a PHP value again, use unserialize(). serialize() handles the types integer, double, string, array (multidimensional) and object (object properties will be serialized, but methods are lost).
Example 1. serialize example

sleep -- ½ÇÇàÀ» Àá½Ã Áö¿¬½ÃŲ´Ù.
void sleep(int seconds);
The sleep function delays program execution for the given number of seconds.
See also usleep().
unpack -- binary ¹®ÀÚ¿À» data·Î unpackÇÑ´Ù.
array unpack
(string format, string data);
Unpack from binary string into array according to format. Returns array containing unpacked elements of binary string.
Unpack works slightly different from Perl as the unpacked data is stored in an associative array. To accomplish this you have to name the different format codes and separate them by a slash /.
Example 1. unpack format string
The resulting array will contain the entries "chars1", "chars2" and "int". |
For an explanation of the format codes see also: pack()
Note that PHP internally stores integral values as signed. If you unpack a large unsigned long and it is of the same size as PHP internally stored values the result will be a negative number even though unsigned unpacking was specified.
unserialize -- ÀúÀå°¡´ÉÇÑ ÇüÅ·ΠǥÇöµÈ ¹®ÀÚ¿À» PHP °ªÀ¸·Î ¸¸µé¾îÁØ´Ù.
creates a PHP value from a stored representation
mixed unserialize
(string str);
unserialize() takes a single serialized variable (see serialize()) and converts it back into a PHP value. The converted value is returned, and can be an integer, double, string, array or object. If an object was serialized, its methods are not preserved in the returned value.
Example 1. unserialize example

uniqid -- À¯ÀÏÇÑ id¸¦ »ý¼ºÇÑ´Ù.
int uniqid
(string prefix);
uniqid() returns a prefixed unique identifier based on current time in microseconds. The prefix can be useful for instance if you generate identifiers simultaneously on several hosts that might happen to generate the identifier at the same microsecond. The prefix can be up to 114 characters long.
If you need a unique identifier or token and you intend to give out that token to the user via the network (i.e. session cookies), it is recommended that you use something along the lines of
$token = md5(uniqid("")); // no random portion$better_token = md5(uniqid(random())); // better, difficult to guess
This will create a 32 character identifier (a 128 bit hex number) that is extremely difficult to predict.
usleep -- ½ÇÇàÀ» ¹é¸¸ºÐÀÇ ÀÏÃÊ ´ÜÀ§·Î Áö¿¬½ÃŲ´Ù.
void usleep(int micro_seconds);
The sleep function delays program execution for the given number of micro_seconds.
See also sleep().
msql -- mSQL ÁúÀǸ¦ Àü¼ÛÇÑ´Ù.
int msql(string database, string query, int link_identifier);
Returns a positive mSQL result identifier to the query result, or false on error.
msql() selects a database and executes a query on it. If the optional link identifier isn't specified, the function will try to find an open link to the mSQL server and if no such link is found it'll try to create one as if msql_connect() was called with no arguments (see msql_connect()).
msql_affected_rows -- ÃÖ±Ù ÁúÀÇ¿¡ ¿µÇâÀ» ¹Þ´Â rowÀÇ °³¼ö¸¦ ±¸ÇÑ´Ù.
int msql_affected_rows
(int query_identifier);
Returns number of affected ("touched") rows by a specific query (i.e. the number of rows returned by a SELECT, the number of rows modified by an update, or the number of rows removed by a delete).
See also: msql_query()
msql_close -- mSQL connectionÀ» ´Ý´Â´Ù.
int msql_close(int link_identifier);
Returns true on success, false on error.
msql_close() closes the link to a mSQL database that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.
Note that this isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
msql_close() will not close persistent links generated by msql_pconnect().
See also: msql_connect() and msql_pconnect().
msql_connect -- mSQL connectionÀ» ¿¬´Ù.
int msql_connect(string hostname);
Returns a positive mSQL link identifier on success, or false on error.
msql_connect() establishes a connection to a mSQL server. The hostname argument is optional, and if it's missing, localhost is assumed.
In case a second call is made to msql_connect() with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned.
The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling msql_close().
See also msql_pconnect(), msql_close().
msql_create_db -- mSQL database¸¦ ¸¸µç´Ù.
int msql_create_db
(string database name, int [link_identifier] );
msql_create_db() attempts to create a new database on the server associated with the specified link identifier.
See also: msql_drop_db().
msql_createdb -- mSQL database¸¦ ¸¸µç´Ù.
int msql_createdb
(string database name, int [link_identifier] );
Identical to msql_create_db().
msql_data_seek -- ³»ºÎÀûÀÎ row pointer¸¦ À̵¿ÇÑ´Ù.
int msql_data_seek(int result_identifier, int row_number);
Returns true on success, false on failure.
msql_data_seek() moves the internal row pointer of the mSQL result associated with the specified result identifier to pointer to the specifyed row number. The next call to msql_fetch_row() would return that row.
See also: msql_fetch_row().
msql_dbname -- ÇöÀç mSQL databaseÀÇ À̸§À» ±¸ÇÑ´Ù.
string msql_dbname(string result, int i);
msql_dbname() returns the database name stored in position i of the result pointer returned from the msql_listdbs() function. The msql_numrows() function can be used to determine how many database names are available.
msql_drop_db -- mSQL database¸¦ ¹ö¸°´Ù.(drop = delete)
int msql_drop_db(string database_name, int link_identifier);
Returns true on success, false on failure.
msql_drop_db() attempts to drop (remove) an entire database from the server associated with the specified link identifier.
See also: msql_create_db().
msql_dropdb -- mSQL database¸¦ ¹ö¸°´Ù.(drop = delete)
See msql_drop_db().
msql_error -- ¸¶Áö¸· mSQL È£ÃâÀÇ ¿¡·¯ ¸Þ¼¼Áö¸¦ ¹ÝȯÇÑ´Ù.
string msql_error( );
Errors coming back from the mSQL database backend no longer issue warnings. Instead, use these functions to retrieve the error string.
msql_fetch_array -- row¸¦ ¹è¿·Î °¡Á®¿Â´Ù.
int msql_fetch_array
(int result);
Returns an array that corresponds to the fetched row, or false if there are no more rows.
msql_fetch_array() is an extended version of msql_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.
Be careful if you are retrieving results from a query that may return a record that contains only one field that has a value of 0 (or an empty string, or NULL).
An important thing to note is that using msql_fetch_array() is NOT significantly slower than using msql_fetch_row(), while it provides a significant added value.
For further details, also see msql_fetch_row()
msql_fetch_field -- Çʵå Á¤º¸¸¦ ±¸ÇÑ´Ù.
object msql_fetch_field(int result, int field_offset);
Returns an object containing field information
msql_fetch_field() can be used in order to obtain information about fields in a certain query result. If the field offset isn't specified, the next field that wasn't yet retreived by msql_fetch_field() is retreived.
The properties of the object are:
name - column name
table - name of the table the column belongs to
not_null - 1 if the column cannot be null
primary_key - 1 if the column is a primary key
unique - 1 if the column is a unique key
type - the type of the column
See also msql_field_seek().
msql_fetch_object -- row¸¦ °´Ã¼(Object)·Î °¡Á®¿Â´Ù.
int msql_fetch_object(int result);
Returns an object with properties that correspond to the fetched row, or false if there are no more rows.
msql_fetch_object() is similar to msql_fetch_array(), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).
Speed-wise, the function is identical to msql_fetch_array(), and almost as quick as msql_fetch_row() (the difference is insignificant).
See also: msql_fetch_array() and msql_fetch_row().
msql_fetch_row -- row¸¦ ¹è¿(enumerated array)·Î °¡Á®¿Â´Ù.
array msql_fetch_row(int result);
Returns an array that corresponds to the fetched row, or false if there are no more rows.
msql_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.
Subsequent call to msql_fetch_row() would return the next row in the result set, or false if there are no more rows.
See also: msql_fetch_array(), msql_fetch_object(), msql_data_seek(), and msql_result().
msql_fieldname -- Çʵå À̸§À» ±¸ÇÑ´Ù.
string msql_fieldname(int result, int field);
msql_fieldname() returns the name of the specified field. result is the result identifier, and field is the field index. msql_fieldname($result, 2); will return the name of the second field in the result associated with the result identifier.
msql_field_seek -- ÇʵåÀÇ offsetÀ» ¼³Á¤ÇÑ´Ù.
int msql_field_seek(int result, int field_offset);
Seeks to the specified field offset. If the next call to msql_fetch_field() won't include a field offset, this field would be returned.
See also: msql_fetch_field().
msql_fieldtable -- ÇØ´ç Çʵ带 °¡Á® ¿Â Table À̸§À» ±¸ÇÑ´Ù.
int msql_fieldtable(int result, int field);
Returns the name of the table field was fetched from.
msql_fieldtype -- Çʵå typeÀ» ±¸ÇÑ´Ù.
string msql_fieldtype(string result, int i);
msql_fieldtype() is similar to the msql_fieldname() function. The arguments are identical, but the field type is returned. This will be one of "int", "string" or "real".
msql_fieldflags -- Çʵå flag¸¦ ±¸ÇÑ´Ù.
string msql_fieldflags(string result, int i);
msql_fieldflags() returns the field flags of the specified field. Currently this is either, "not null", "primary key", a combination of the two or "" (an empty string).
msql_fieldlen -- ÇÊµå ±æÀ̸¦ ±¸ÇÑ´Ù.
int msql_fieldlen(string result, int i);
msql_fieldlen() returns the length of the specified field.
msql_free_result -- result memory¸¦ Ç®¾îÁØ´Ù.
int msql_free_result(int result);
msql_free_result() frees the memory associated with result. When PHP completes a request, this memory is freed automatically, so you only need to call this function when you want to make sure you don't use too much memory while the script is running.
msql_freeresult -- result memory¸¦ Ç®¾îÁØ´Ù.
msql_list_fields -- result fieldµéÀ» ³ª¿ÇÑ´Ù.
int msql_list_fields(string database, string tablename);
msql_list_fields() retrieves information about the given tablename. Arguments are the database name and the table name. A result pointer is returned which can be used with msql_fieldflags(), msql_fieldlen(), msql_fieldname(), and msql_fieldtype(). A result identifier is a positive integer. The function returns -1 if a error occurs. A string describing the error will be placed in $phperrmsg, and unless the function was called as @msql_list_fields() then this error string will also be printed out.
See also msql_error().

msql_list_dbs -- serverÀÇ mSQL databaseµéÀ» ³ª¿ÇÑ´Ù.
int msql_list_dbs(void);
msql_list_dbs() will return a result pointer containing the databases available from the current msql daemon. Use the msql_dbname() function to traverse this result pointer.

See msql_list_dbs().
msql_list_tables -- mSQL databaseÀÇ tableµéÀ» ³ª¿ÇÑ´Ù.
int msql_list_tables(string database);
msql_list_tables() takes a database name and result pointer much like the msql() function. The msql_tablename() function should be used to extract the actual table names from the result pointer.
msql_listtables -- mSQL databaseÀÇ tableµéÀ» ³ª¿ÇÑ´Ù.
See msql_list_tables().
msql_num_fields -- resultÀÇ field °³¼ö¸¦ ±¸ÇÑ´Ù.
int msql_num_fields(int result);
msql_num_fields() returns the number of fields in a result set.
See also: msql(), msql_query(), msql_fetch_field(), and msql_num_rows().
msql_num_rows -- resultÀÇ row °³¼ö¸¦ ±¸ÇÑ´Ù.
int msql_num_rows(string result);
msql_num_rows() returns the number of rows in a result set.
See also: msql(), msql_query(), and msql_fetch_row().
msql_numfields -- resultÀÇ field °³¼ö¸¦ ±¸ÇÑ´Ù.
int msql_numfields(void);
Identical to msql_num_fields().
msql_numrows -- resultÀÇ row °³¼ö¸¦ ±¸ÇÑ´Ù.
int msql_numrows(void);
Identical to msql_num_rows().
msql_pconnect -- ¿µ±¸ÀûÀÎ mSQL Á¢¼ÓÀ» ¿¬´Ù.
int msql_pconnect(string hostname);
Returns a positive mSQL persistent link identifier on success, or false on error.
msql_pconnect() acts very much like msql_connect() with two major differences.
First, when connecting, the function would first try to find a (persistent) link that's already open with the same host. If one is found, an identifier for it will be returned instead of opening a new connection.
Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (msql_close() will not close links established by msql_pconnect()).
This type of links is therefore called 'persistent'.
msql_query -- mSQL ÁúÀǸ¦ Àü¼ÛÇÑ´Ù.
int msql_query(string query, int link_identifier);
msql_query() sends a query to the currently active database on the server that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed. If no link is open, the function tries to establish a link as if msql_connect() was called, and use it.
Returns a positive mSQL result identifier on success, or false on error.
See also: msql(), msql_select_db(), and msql_connect().
msql_regcase -- Á¤±Ô Ç¥Çö½Ä(regular expression)À» ´ë,¼Ò¹®ÀÚ¸¦ °¡¸®Áö ¾Êµµ·Ï ÇÑ´Ù.
See sql_regcase().
msql_result -- result data¸¦ ±¸ÇÑ´Ù.
int msql_result(int result, int i, mixed field);
Returns the contents of the cell at the row and offset in the specified mSQL result set.
msql_result() returns the contents of one cell from a mSQL result set. The field argument can be the field's offset, or the field's name, or the field's table dot field's name (fieldname.tablename). If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column name.
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they're MUCH quicker than msql_result(). Also, note that specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
Recommended high-performance alternatives: msql_fetch_row(), msql_fetch_array(), and msql_fetch_object().
msql_select_db -- mSQL database¸¦ ¼±ÅÃÇÑ´Ù.
int msql_select_db(string database_name, int link_identifier);
Returns true on success, false on error.
msql_select_db() sets the current active database on the server that's associated with the specified link identifier. If no link identifier is specified, the last opened link is assumed. If no link is open, the function will try to establish a link as if msql_connect() was called, and use it.
Every subsequent call to msql_query() will be made on the active database.
See also: msql_connect(), msql_pconnect(), and msql_query().
msql_selectdb -- mSQL database¸¦ ¼±ÅÃÇÑ´Ù.
See msql_select_db().
msql_tablename -- ÇØ´ç Çʵ带 °¡Á® ¿Â Table À̸§À» ±¸ÇÑ´Ù.
string msql_tablename(int result, int field);
msql_tablename() takes a result pointer returned by the msql_list_tables() function as well as an integer index and returns the name of a table. The msql_numrows() function may be used to determine the number of tables in the result pointer.
Example 1. msql_tablename() example <?php msql_connect ("localhost"); $result = msql_list_tables("wisconsin"); $i = 0; while ($i < msql_numrows($result)) { $tb_names[$i] = msql_tablename($result, $i); echo $tb_names[$i] . "<BR>"; $i++; } ?> |

int mssql_affected_rows
(int [link_identifier] );
Returns: The number of affected rows by the last query.
mssql_affected_rows() returns the number of rows affected by the last INSERT, UPDATE or DELETE query on the server associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.
This command is not effective for SELECT statements, only on statements which modify records. To retrieve the number of rows returned from a SELECT, use mssql_num_rows().
mssql_close -- MS SQL Server connectionÀ» ´Ý´Â´Ù.
int mssql_close
(int link_identifier);
Returns: true on success, false on error
mssql_close() closes the link to a MS SQL Server database that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.
Note that this isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
mssql_close() will not close persistent links generated by mssql_pconnect().
See also: mssql_connect(), mssql_pconnect().
mssql_connect -- MS SQL server connectionÀ» ¿¬´Ù.
int mssql_connect
(string servername, string username, string password);
Returns: A positive MS SQL link identifier on success, or false on error.
mssql_connect() establishes a connection to a MS SQL server. The servername argument has to be a valid servername that is defined in the 'interfaces' file.
In case a second call is made to mssql_connect() with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned.
The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling mssql_close().
See also mssql_pconnect(), mssql_close().
mssql_data_seek -- internal row pointer¸¦ ¿Å±ä´Ù.
int mssql_data_seek
(int result_identifier, int row_number);
Returns: true on success, false on failure
mssql_data_seek() moves the internal row pointer of the MS SQL result associated with the specified result identifier to pointer to the specifyed row number. The next call to mssql_fetch_row() would return that row.
See also: mssql_data_seek().
mssql_fetch_array -- row¸¦ ¹è¿·Î °¡Á®¿Â´Ù.
int mssql_fetch_array
(int result);
Returns: An array that corresponds to the fetched row, or false if there are no more rows.
mssql_fetch_array() is an extended version of mssql_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.
An important thing to note is that using mssql_fetch_array() is NOT significantly slower than using mssql_fetch_row(), while it provides a significant added value.
For further details, also see mssql_fetch_row()
mssql_fetch_field -- ÇʵåÀÇ Á¤º¸¸¦ ±¸ÇÑ´Ù.
object mssql_fetch_field

Returns an object containing field information.
mssql_fetch_field() can be used in order to obtain information about fields in a certain query result. If the field offset isn't specified, the next field that wasn't yet retreived by mssql_fetch_field() is retreived.
The properties of the object are:
name - column name. if the column is a result of a function, this property is set to computed#N, where #N is a serial number.
column_source - the table from which the column was taken
max_length - maximum length of the column
numeric - 1 if the column is numeric
See also mssql_field_seek()
mssql_fetch_object -- row¸¦ object·Î °¡Á®¿Â´Ù.
int mssql_fetch_object
(int result);
Returns: An object with properties that correspond to the fetched row, or false if there are no more rows.
mssql_fetch_object() is similar to mssql_fetch_array(), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).
Speed-wise, the function is identical to mssql_fetch_array(), and almost as quick as mssql_fetch_row() (the difference is insignificant).
See also: mssql_fetch-array() and mssql_fetch-row().
mssql_fetch_row -- row¸¦ ¹è¿(enumerated array)·Î °¡Á®¿Â´Ù.
array mssql_fetch_row
(int result);
Returns: An array that corresponds to the fetched row, or false if there are no more rows.
mssql_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.
Subsequent call to mssql_fetch_rows() would return the next row in the result set, or false if there are no more rows.

mysql_list_dbs -- serverÀÇ MySQL databaseµéÀ» ³ª¿ÇÑ´Ù.
int mysql_listdbs(void);
mysql_listdbs() will return a result pointer containing the databases available from the current mysql daemon. Use the mysql_dbname() function to traverse this result pointer.
For downward compatibility mysql_listdbs() can also be used.
mysql_list_tables -- MySQL databaseÀÇ tableµéÀ» ³ª¿ÇÑ´Ù.
int mysql_list_tables(string database);
mysql_list_tables() takes a database name and result pointer much like the mysql_db_query() function. The mysql_tablename() function should be used to extract the actual table names from the result pointer.
For downward compatibility mysql_listtables() can also be used.
mysql_num_fields -- resultÀÇ field °³¼ö¸¦ ±¸ÇÑ´Ù.
int mysql_num_fields(int result);
mysql_num_fields() returns the number of fields in a result set.
See also: mysql_db_query(), mysql_query(), mysql_fetch_field(), mysql_num_rows().
For downward compatibility mysql_numfields() can also be used.
mysql_num_rows -- resultÀÇ row °³¼ö¸¦ ±¸ÇÑ´Ù.
int mysql_num_rows(string result);
mysql_num_rows() returns the number of rows in a result set.
See also: mysql_db_query(), mysql_query() and, mysql_fetch_row().
For downward compatibility mysql_numrows() can also be used.
mysql_pconnect -- ¿µ±¸ÀûÀÎ MySQL Á¢¼ÓÀ» ¿¬´Ù.
int mysql_pconnect
(string [hostname] , string [username] , string [password] );
Returns: A positive MySQL persistent link identifier on success, or false on error
mysql_pconnect() acts very much like mysql_connect() with two major differences.
First, when connecting, the function would first try to find a (persistent) link that's already open with the same host, username and password. If one is found, an identifier for it will be returned instead of opening a new connection.
Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (mysql_close() will not close links established by mysql_pconnect()).
This type of links is therefore called 'persistent'.
mysql_query -- MySQL ÁúÀǸ¦ Àü¼ÛÇÑ´Ù.
int mysql_query
(string query, int [link_identifier] );
mysql_query() sends a query to the currently active database on the server that's associated with the specified link identifier. If link_identifier isn't specified, the last opened link is assumed. If no link is open, the function tries to establish a link as if mysql_connect() was called, and use it.

mysql_result -- result data¸¦ ±¸ÇÑ´Ù.
int mysql_result
(int result, int row, mixed field);
mysql_result() returns the contents of one cell from a MySQL result set. The field argument can be the field's offset, or the field's name, or the field's table dot field's name (fieldname.tablename). If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column name.
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they're MUCH quicker than mysql_result(). Also, note that specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
Calls mysql_result() should not be mixed with calls to other functions that deal with the result set.
Recommended high-performance alternatives: mysql_fetch_row(), mysql_fetch_array(), and mysql_fetch_object().
mysql_select_db -- MySQL database¸¦ ¼±ÅÃÇÑ´Ù.
int mysql_select_db
(string database_name, int [link_identifier] );
Returns: true on success, false on error
mysql_select_db() sets the current active database on the server that's associated with the specified link identifier. If no link identifier is specified, the last opened link is assumed. If no link is open, the function will try to establish a link as if mysql_connect() was called, and use it.
Every subsequent call to mysql_query() will be made on the active database.
See also: mysql_connect(), mysql_pconnect(), and mysql_query()
For downward compatibility mysql_selectdb() can also be used.
mysql_tablename -- ÇØ´ç Çʵ带 °¡Á® ¿Â Table À̸§À» ±¸ÇÑ´Ù.
string mysql_tablename(int result, int i);
mysql_tablename() takes a result pointer returned by the mysql_list_tables() function as well as an integer index and returns the name of a table. The mysql_num_rows() function may be used to determine the number of tables in the result pointer.
Example 1. mysql_tablename() example <?php mysql_connect ("localhost:3306"); $result = mysql_listtables ("wisconsin"); $i = 0; while ($i < mysql_num_rows ($result)) { $tb_names[$i] = mysql_tablename ($result, $i); echo $tb_names[$i] . "<BR>"; $i++; } ?> |
sybase_affected_rows -- ÃÖ±Ù ÁúÀÇ¿¡ ¿µÇâÀ» ¹Þ´Â rowÀÇ °³¼ö¸¦ ±¸ÇÑ´Ù.
int sybase_affected_rows
(int [link_identifier] );
Returns: The number of affected rows by the last query.
sybase_affected_rows() returns the number of rows affected by the last INSERT, UPDATE or DELETE query on the server associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.
This command is not effective for SELECT statements, only on statements which modify records. To retrieve the number of rows returned from a SELECT, use sybase_num_rows().
sybase_close -- Sybase connectionÀ» ´Ý´Â´Ù.
int sybase_close(int link_identifier);
Returns: true on success, false on error
sybase_close() closes the link to a Sybase database that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed.
Note that this isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
sybase_close() will not close persistent links generated by sybase_pconnect().
See also: sybase_connect(), sybase_pconnect().
sybase_connect -- Sybase server connectionÀ» ¿¬´Ù.
int sybase_connect(string servername, string username, string password);
Returns: A positive Sybase link identifier on success, or false on error.
sybase_connect() establishes a connection to a Sybase server. The servername argument has to be a valid servername that is defined in the 'interfaces' file.
In case a second call is made to sybase_connect() with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned.
The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling sybase_close().
See also sybase_pconnect(), sybase_close().
sybase_data_seek -- internal row pointer¸¦ ¿Å±ä´Ù.
int sybase_data_seek(int result_identifier, int row_number);
Returns: true on success, false on failure
sybase_data_seek() moves the internal row pointer of the Sybase result associated with the specified result identifier to pointer to the specifyed row number. The next call to sybase_fetch_row() would return that row.
See also: sybase_data_seek().
sybase_fetch_array -- row¸¦ ¹è¿·Î °¡Á®¿Â´Ù.
int sybase_fetch_array(int result);
Returns: An array that corresponds to the fetched row, or false if there are no more rows.
sybase_fetch_array() is an extended version of sybase_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.
An important thing to note is that using sybase_fetch_array() is NOT significantly slower than using sybase_fetch_row(), while it provides a significant added value.
For further details, also see sybase_fetch_row()
sybase_fetch_field -- Çʵå Á¤º¸¸¦ ±¸ÇÑ´Ù.
object sybase_fetch_field(int result, int field_offset);
Returns an object containing field information.
sybase_fetch_field() can be used in order to obtain information about fields in a certain query result. If the field offset isn't specified, the next field that wasn't yet retreived by sybase_fetch_field() is retreived.
The properties of the object are:
name - column name. if the column is a result of a function, this property is set to computed#N, where #N is a serial number.
column_source - the table from which the column was taken
max_length - maximum length of the column
numeric - 1 if the column is numeric
See also sybase_field_seek()
sybase_fetch_object -- row¸¦ °´Ã¼(Object)·Î °¡Á®¿Â´Ù.
int sybase_fetch_object(int result);
Returns: An object with properties that correspond to the fetched row, or false if there are no more rows.
sybase_fetch_object() is similar to sybase_fetch_array(), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).
Speed-wise, the function is identical to sybase_fetch_array(), and almost as quick as sybase_fetch_row() (the difference is insignificant).
See also: sybase_fetch-array() and sybase_fetch-row().
sybase_fetch_row -- row¸¦ ¹è¿(enumerated array)·Î °¡Á®¿Â´Ù.
array sybase_fetch_row(int result);
Returns: An array that corresponds to the fetched row, or false if there are no more rows.
sybase_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.
Subsequent call to sybase_fetch_rows() would return the next row in the result set, or false if there are no more rows.
See also: sybase_fetch_array(), sybase_fetch_object(), sybase_data_seek(), sybase_fetch_lengths(), and sybase_result().
sybase_field_seek -- ÇʵåÀÇ offsetÀ» ¼³Á¤ÇÑ´Ù.
int sybase_field_seek(int result, int field_offset);
Seeks to the specified field offset. If the next call to sybase_fetch_field() won't include a field offset, this field would be returned.
See also: sybase_fetch_field().
sybase_free_result -- result memory¸¦ Ç®¾îÁØ´Ù.
int sybase_free_result
(int result);
sybase_free_result() only needs to be called if you are worried about using too much memory while your script is running. All result memory will automatically be freed when the script, you may call sybase_free_result() with the result identifier as an argument and the associated result memory will be freed.
sybase_num_fields -- resultÀÇ field °³¼ö¸¦ ±¸ÇÑ´Ù.
int sybase_num_fields(int result);
sybase_num_fields() returns the number of fields in a result set.
See also: sybase_db_query(), sybase_query(), sybase_fetch_field(), sybase_num_rows().
sybase_num_rows -- resultÀÇ row °³¼ö¸¦ ±¸ÇÑ´Ù.
int sybase_num_rows(string result);
sybase_num_rows() returns the number of rows in a result set.

sybase_pconnect -- ¿µ±¸ÀûÀÎ Sybase Á¢¼ÓÀ» ¿¬´Ù.
int sybase_pconnect(string servername, string username, string password);
Returns: A positive Sybase persistent link identifier on success, or false on error
sybase_pconnect() acts very much like sybase_connect() with two major differences.
First, when connecting, the function would first try to find a (persistent) link that's already open with the same host, username and password. If one is found, an identifier for it will be returned instead of opening a new connection.
Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (sybase_close() will not close links established by sybase_pconnect()).
This type of links is therefore called 'persistent'.
sybase_query -- Sybase ÁúÀǸ¦ Àü¼ÛÇÑ´Ù.
int sybase_query(string query, int link_identifier);
Returns: A positive Sybase result identifier on success, or false on error.
sybase_query() sends a query to the currently active database on the server that's associated with the specified link identifier. If the link identifier isn't specified, the last opened link is assumed. If no link is open, the function tries to establish a link as if sybase_connect() was called, and use it.
See also: sybase_db_query(), sybase_select_db(), and sybase_connect().
sybase_result -- result data¸¦ ±¸ÇÑ´Ù.
int sybase_result(int result, int i, mixed field);
Returns: The contents of the cell at the row and offset in the specified Sybase result set.
sybase_result() returns the contents of one cell from a Sybase result set. The field argument can be the field's offset, or the field's name, or the field's table dot field's name (fieldname.tablename). If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column name.
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these functions return the contents of multiple cells in one function call, they're MUCH quicker than sybase_result(). Also, note that specifying a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
Recommended high-performance alternatives: sybase_fetch_row(), sybase_fetch_array(), and sybase_fetch_object().
sybase_select_db -- Sybase database¸¦ ¼±ÅÃÇÑ´Ù.
int sybase_select_db(string database_name, int link_identifier);
Returns: true on success, false on error
sybase_select_db() sets the current active database on the server that's associated with the specified link identifier. If no link identifier is specified, the last opened link is assumed. If no link is open, the function will try to establish a link as if sybase_connect() was called, and use it.
Every subsequent call to sybase_query() will be made on the active database.
See also: sybase_connect(), sybase_pconnect(), and sybase_query()
fsockopen -- InternetÀ̳ª Unix domainÀÇ socket connectionÀ» ¿¬´Ù.
int fsockopen
(string hostname, int port, int [errno], string [errstr]);
Opens an Internet domain socket connection to hostname on port port and returns a file pointer, which may be used by fgets(), fgetss(), fputs(), and fclose(). If the call fails, it will return FALSE and if the optional errno and errstr arguments are present they will be set to indicate the actual system level error that ocurred on the system-level connect() call. If the returned errno is 0, but the function returned FALSE, it is an indication that the error occurred before the connect() call. This is most likely due to a problem initializing the socket. Note that the errno and errstr arguments should be passed by reference.
If port is 0 and the operating system supports Unix domain sockets, hostname will be used as the filename of a Unix domain socket to connect to.
The socket will by default be opened in blocking mode. You can switch it to non-blocking mode by using the set_socket_blocking().
Example 1. fsockopen example $fp = fsockopen("www.php.net", 80, &$errno, &$errstr); if(!$fp) { echo "$errstr ($errno)<br>\n"; } else { while(!feof($fp)) { echo fgets($fp,128); } fclose($fp); } |
pfsockopen -- ¿µ±¸ÀûÀÎ(persistent) InternetÀ̳ª Unix domainÀÇ socket ¿¬°áÀ» ¿¬´Ù.
int pfsockopen
(string hostname, int port, int [errno], string [errstr]);
This function behaves exactly as fsockopen() with the difference that the connection is not closed after the request is finished. It is the persistent version of fsockopen.
set_socket_blocking -- ¼ÒÄÏÀÇ blocking/non-blocking ¸ðµå¸¦ ¼³Á¤ÇÑ´Ù.
int set_socket_blocking(int socket descriptor, int mode);
If mode is false, the given socket descriptor will be switched to non-blocking mode, and if true, it will be switched to blocking mode. This affects calls like fgets() that read from the socket. In non-blocking mode an fgets() call will always return right away while in blocking mode it will wait for data to become available on the socket.
gethostbyaddr -- ÁÖ¾îÁø IP address¿¡ ÇØ´çÇÏ´Â Internet host nameÀ» ±¸ÇÑ´Ù.
string gethostbyaddr(string ip_address);
Returns the host name of the Internet host specified by ip_address. If an error occurs, returns ip_address.

openlog -- system logger·ÎÀÇ connectionÀ» ¿¬´Ù.
void openlog(string ident, int option, int facility);
openlog() opens a connection to the system logger for a program. The string ident is added to each message. Values for option and facility are given in the next section. The use of openlog() is optional; It will automatically be called by syslog() if necessary, in which case ident will default to false. See also syslog() and closelog().
syslog -- system log message¸¦ ¸¸µç´Ù.
void syslog(int priority, string message);
syslog() generates a log message that will be distributed by the system logger. priority is a combination of the facility and the level, values for which are given in the next section. The remaining argument is the message to send, except that the two characters %m will be replaced by the error message string (strerror) corresponding to the present value of errno.
More information on the syslog facilities can be found in the man pages for syslog on Unix machines.
On Windows NT, the syslog service is emulated using the Event Log.
closelog -- system logger·ÎÀÇ connectionÀ» ´Ý´Â´Ù.

odbc_autocommit -- autocommit ±â´ÉÀ» ÄÑ°í, ²ö´Ù.
int odbc_autocommit
(int connection_id, int [OnOff]);
Without the OnOff parameter, this function returns auto-commit status for connection_id. True is returned if auto-commit is on, false if it is off or an error occurs.
If OnOff is true, auto-commit is enabled, if it is false auto-commit is disabled. Returns true on success, false on failure.
By default, auto-commit is on for a connection. Disabling auto-commit is equivalent with starting a transaction.
See also odbc_commit() and odbc_rollback().
odbc_binmode -- binary column data¸¦ ´Ù·é´Ù.
int odbc_binmode
(int result_id, int mode);
(ODBC SQL types affected: BINARY, VARBINARY, LONGVARBINARY)
ODBC_BINMODE_PASSTHRU: Passthru BINARY data
ODBC_BINMODE_RETURN: Return as is
ODBC_BINMODE_CONVERT: Convert to char and return
When binary SQL data is converted to character C data, each byte (8 bits) of source data is represented as two ASCII characters. These characters are the ASCII character representation of the number in its hexadecimal form. For example, a binary 00000001 is converted to "01" and a binary 11111111 is converted to "FF".

If odbc_fetch_into() is used, passthru means that an empty string is returned for these columns.
If result_id is 0, the settings apply as default for new results.
Note: Default for longreadlen is 4096 and binmode defaults to ODBC_BINMODE_RETURN. Handling of binary long columns is also affected by odbc_longreadlen()
odbc_close -- ODBC connectionÀ» ´Ý´Â´Ù.
void odbc_close(int connection_id);
odbc_close() will close down the connection to the database server associated with the given connection identifier.
NOTE: This function will fail if there are open transactions on this connection. The connection will remain open in this case.
odbc_close_all -- ¸ðµç ODBC connectionµéÀ» ´Ý´Â´Ù.

odbc_connect -- datasource¿Í ¿¬°áÇÑ´Ù.
int odbc_connect(string dsn, string user, string password);
Returns an ODBC connection id or 0 (false) on error.
The connection id returned by this functions is needed by other ODBC functions. You can have multiple connections open at once. For persistent connections see odbc_pconnect().
odbc_cursor -- cursornameÀ» ±¸ÇÑ´Ù.
string odbc_cursor(int result_id);
odbc_cursor will return a cursorname for the given result_id.
odbc_do -- odbc_exec()¿Í °°´Ù.
string odbc_do(int conn_id, string query);
odbc_do will execute a query on the given connection
odbc_exec -- SQL ¹®ÀåÀ» ÁغñÇÏ°í ½ÇÇàÇÑ´Ù.
int odbc_exec(int connection_id, string query_string);
Returns false on error. Returns an ODBC result identifier if the SQL command was executed successfully.
odbc_exec() will send an SQL statement to the database server specified by connection_id. This parameter must be a valid identifier returned by odbc_connect() or odbc_pconnect().
See also: odbc_prepare() and odbc_execute() for multiple execution of SQL statements.
odbc_execute -- ½ÇÇàÇÒ Áغñ°¡ µÈ ¹®ÀåÀ» ½ÇÇàÇÑ´Ù.
int odbc_execute
(int result_id, array [parameters_array]);
Executes a statement prepared with odbc_prepare(). Returns true on successful execution, false otherwise. The array arameters_array only needs to be given if you really have parameters in your statement.
odbc_fetch_into -- ÇÑ°³ÀÇ result row¸¦ ¹è¿·Î °¡Á®¿Â´Ù.
int odbc_fetch_into
(int result_id, int [rownumber], array result_array);
Returns the number of columns in the result; false on error. result_array must be passed by reference, but it can be of any type since it will be converted to type array. The array will contain the column values starting at array index 0.
odbc_fetch_row -- row¸¦ °¡Á®¿Â´Ù.
int odbc_fetch_row
(int result_id, int [row_number]);
If odbc_fetch_row() was succesful (there was a row), true is returned. If there are no more rows, false is returned.
odbc_fetch_row() fetches a row of the data that was returned by odbc_do() / odbc_exec(). After odbc_fetch_row() is called, the fields of that row can be accessed with odbc_result().
If row_number is not specified, odbc_fetch_row() will try to fetch the next row in the result set. Calls to odbc_fetch_row() with and without row_number can be mixed.
To step through the result more than once, you can call odbc_fetch_row() with row_number 1, and then continue doing odbc_fetch_row() without row_number to review the result. If a driver doesn't support fetching rows by number, the row_number parameter is ignored.
odbc_field_name -- columnnameÀ» ±¸ÇÑ´Ù.
string odbc_fieldname(int result_id, int field_number);
odbc_field_name() will return the name of the field occupying the given column number in the given ODBC result identifier. Field numbering starts at 1. false is returned on error.

string odbc_field_type
(int result_id, int field_number);
odbc_field_type() will return the length of the field referecend by number in the given ODBC result identifier. Field numbering starts at 1.
odbc_free_result -- ÁöÁ¤µÈ result¿¡ °ü·ÃµÈ resource¸¦ ÇØÁ¦ÇÑ´Ù.
int odbc_free_result(int result_id);
Always returns true.
odbc_free_result() only needs to be called if you are worried about using too much memory while your script is running. All result memory will automatically be freed when the script is finished. But, if you are sure you are not going to need the result data anymore in a script, you may call odbc_free_result(), and the memory associated with result_id will be freed.
NOTE: If auto-commit is disabled (see odbc_autocommit()) and you call odbc_free_result() before commiting, all pending transactions are rolled back.
odbc_longreadlen -- LONG columnµéÀ» ´Ù·é´Ù.
int odbc_longreadlen(int result_id, int length);
(ODBC SQL types affected: LONG, LONGVARBINARY) The number of bytes returned to PHP is controled by the parameter length. If it is set to 0, Long column data is passed thru to the client.
NOTE: Handling of LONGVARBINARY columns is also affected by odbc_binmode()
odbc_num_fields -- resultÀÇ column °³¼ö
int odbc_num_fields(int result_id);
odbc_num_fields() will return the number of fields (columns) in an ODBC result. This function will return -1 on error. The argument is a valid result identifier returned by odbc_exec().
odbc_pconnect -- ¿µ±¸ÀûÀÎ database connectionÀ» ¿¬´Ù.
int odbc_pconnect(string dsn, string user, string password);
Returns an ODBC connection id or 0 (false) on error. This function is much like odbc_connect(), except that the connection is not really closed when the script has finished. Future requests for a connection with the same dsn, user, password combination (via odbc_connect() and odbc_pconnect()) can reuse the persistent connection.
NOTE: Persistent connections have no effect if PHP is used as a CGI program.
For more information on persistent connections, refer to the PHP3 FAQ.
odbc_prepare -- ½ÇÇàÇÒ ¹®ÀåÀ» ÁغñÇÑ´Ù.
int odbc_prepare(int connection_id, string query_string);
Returns false on error.
Returns an ODBC result identifier if the SQL command was prepared successfully. The result identifier can be used later to execute the statement with odbc_execute().
odbc_num_rows -- resultÀÇ row °³¼ö
int odbc_num_rows(int result_id);
odbc_num_rows() will return the number of rows in an ODBC result. This function will return -1 on error. For INSERT, UPDATE and DELETE statements odbc_num_rows() returns the number of rows affected. For a SELECT clause this can be the number of rows available.
Note: Using odbc_num_rows() to determine the number of rows available after a SELECT will return -1 with many drivers.
odbc_result -- result data¸¦ ±¸ÇÑ´Ù.
string odbc_result
(int result_id, mixed field);
Returns the contents of the field.
field can either be an integer containing the column number of the field you want; or it can be a string containing the name of the field. For example:
$item_3 = odbc_result($Query_ID, 3 );$item_val = odbc_result($Query_ID, "val");
The first call to odbc_result() returns the value of the third field in the current record of the query result. The second function call to odbc_result() returns the value of the field whose field name is "val" in the current record of the query result. An error occurs if a column number parameter for a field is less than one or exceeds the number of columns (or fields) in the current record. Similarly, an error occurs if a field with a name that is not one of the fieldnames of the table(s) that is(are) being queried.
Field indices start from 1. Regarding the way binary or long column data is returned refer to odbc_binmode() and odbc_longreadlen().
odbc_result_all -- result¸¦ HTML table·Î ÀμâÇÑ´Ù.
int odbc_result_all
(int result_id, string [format]);
Returns the number of rows in the result or false on error.

int odbc_setoption
(int id, int function, int option, int param);
This function allows fiddling with the ODBC options for a particular connection or query result. It was written to help find work arounds to problems in quirky ODBC drivers. You should probably only use this function if you are an ODBC programmer and understand the effects the various options will have. You will certainly need a good ODBC reference to explain all the different options and values that can be used. Different driver versions support different options.
Because the effects may vary depending on the ODBC driver, use of this function in scripts to be made publicly available is strongly discouraged. Also, some ODBC options are not available to this function because they must be set before the connection is established or the query is prepared. However, if on a particular job it can make PHP work so your boss doesn't tell you to use a commercial product, that's all that really matters.
Id is a connection id or result id on which to change the settings.For SQLSetConnectOption(), this is a connection id. For SQLSetStmtOption(), this is a result id.
function is the ODBC function to use. The value should be 1 for SQLSetConnectOption() and 2 for SQLSetStmtOption().
Parmeter option is the option to set.
Parameter param is the value for the given option.

OCIDefineByName -- SELECT ÁßÀÇ degine-stepÀ¸·Î PHP º¯¼ö¸¦ »ç¿ëÇÑ´Ù.
int OCIDefineByName
(int stmt, string Column-Name, mixed &variable, int [type]);
OCIDefineByName() uses fetches SQL-Columns into user-defined PHP-Variables. Be careful that Oracle user ALL-UPPERCASE column-names, whereby in your select you can also write lower-case. OCIDefineByName() expects the Column-Name to be in uppercase. If you define a variable that doesn't exists in you select statement, no error will be given!
If you need to define an abstract Datatype (LOB/ROWID/BFILE) you need to allocate it first using OCINewDescriptor() function. See also the OCIBindByName() function.

OCIBindByName -- PHP º¯¼ö¸¦ Oracle Placeholder·Î bind ÇÑ´Ù.
int OCIBindByName
(int stmt, string ph_name, mixed &variable, intlength, int [type]);
OCIBindByName() binds the PHP variable variable to the Oracle placeholder ph_name. Whether it will be used for input or output will be determined run-time, and the necessary storage space will be allocated. The length paramter sets the maximum length for the bind. If you set length to -1 OCIBindByName() will use the current length of variable to set the maximum length.
If you need to bind an abstract Datatype (LOB/ROWID/BFILE) you need to allocate it first using OCINewDescriptor() function. The length is not used for abstract Datatypes and should be set to -1. The type variable tells oracle, what kind of descriptor we want to use. Possible values are: OCI_B_FILE (Binary-File), OCI_B_CFILE (Character-File), OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and OCI_B_ROWID (ROWID).

then the resulting PHP binary will be dynamically linked against libclntsh.so in /opt/oracle/oracle/lib. The
build process as generated by configure will include this directory with an -L option, but not with an -R
option (run-time library search path). This means that the resulting binary will not be able to find libclntsh.so
by itself, but depends on an appropriate LD_LIBRARY_PATH set within the web server CGI environment -
which usually is not there. To fix this, grab the Makefile generated by configure and duplicate the
-L/opt/oracle/oracle/8.0.3/lib option as an -R/opt/oracle/oracle/8.0.3/lib option (your -L and -R strings will
look slightly different depending on the values for your oracle version and ORACLE_HOME). The -R option
will compile in the corrent search path for libclntsh and you won't have any LD_LIBRARY_PATH pains any
more.

int pg_connect(string host, string port, string options, string tty, string dbname);
Returns a connection index on success, or false if the connection could not be made. Opens a connection to a PostgreSQL database. Each of the arguments should be a quoted string, including the port number. The options and tty arguments are optional and can be left out. This function returns a connection index that is needed by other PostgreSQL functions. You can have multiple connections open at once.
A connection can also established with the following command: $conn = pg_connect("dbname=marliese port=5432"); Other parameters besides dbname and port are host, tty and options.
See also pg_pConnect().
pg_DBname -- database À̸§
string pg_dbname(int connection);
Returns the name of the database that the given PostgreSQL connection index is connected to, or false if connection is not a valid connection index.
pg_ErrorMessage -- ¿¡·¯ ¸Þ¼¼Áö
string pg_errormessage(int connection);
Returns a string containing the error message, false on failure. Details about the error probably cannot be retrieved using the pg_errormessage() function if an error occured on the last database action for which a valid connection exists, this function will return a string containing the error message generated by the backend server.
pg_Exec -- ÁúÀǸ¦ ½ÇÇàÇÑ´Ù.
int pg_exec(int connection, string query);
Returns a result index if query could be executed, false on failure or if connection is not a valid connection index. Details about the error can be retrieved using the pg_ErrorMessage() function if connection is valid. Sends an SQL statement to the PostgreSQL database specified by the connection index. The connection must be a valid index that was returned by pg_Connect(). The return value of this function is an index to be used to access the results from other PostgreSQL functions.
NOTE: PHP2 returned 1 if the query was not expected to return data (inserts or updates, for example) and greater than 1 even on selects that did not return anything. No such assumption can be made in PHP3.
pg_Fetch_Array -- row¸¦ ¹è¿·Î °¡Á®¿Â´Ù.
array pg_fetch_array
(int result, int row);
Returns: An array that corresponds to the fetched row, or false if there are no more rows.
pg_fetch_array() is an extended version of pg_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.
An important thing to note is that using pg_fetch_array() is NOT significantly slower than using pg_fetch_row(), while it provides a significant added value.
For further details, also see pg_fetch_row()
Example 1. PostgreSQL fetch array
|
pg_Fetch_Object -- row¸¦ object·Î °¡Á®¿Â´Ù.
object pg_fetch_object
(int result, int row);
Returns: An object with properties that correspond to the fetched row, or false if there are no more rows.
pg_fetch_object() is similar to pg_fetch_array(), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).
Speed-wise, the function is identical to pg_fetch_array(), and almost as quick as pg_fetch_row() (the difference is insignificant).
See also: pg_fetch_array() and pg_fetch_row().
Example 1. Postgres fetch object
|
pg_Fetch_Row -- row¸¦ ¹è¿(enumerated array)·Î °¡Á®¿Â´Ù.
array pg_fetch_row
(int result, int row);
Returns: An array that corresponds to the fetched row, or false if there are no more rows.
pg_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.
Subsequent call to pg_fetch_row() would return the next row in the result set, or false if there are no more rows.
See also: pg_fetch_array(), pg_fetch_object(), pg_result().

ereg_replace -- regular expressionÀÇ ¹®ÀåÀ» ´ëÄ¡ÇÑ´Ù.
string ereg_replace
(string pattern, string replacement, string string);
This function scans string for matches to pattern, then replaces the matched text with replacement.
If pattern contains parenthesized substrings, replacement may contain substrings of the form \\digit, which will be replaced by the text matching the digit'th parenthesized substring; \\0 will produce the entire contents of string. Up to nine substrings may be used. Parentheses may be nested, in which case they are counted by the opening parenthesis. For example, the following code snippet prints "This was a test" three times:

split -- ¹®ÀÚ¿À» regular expression¿¡ ÀÇÇØ ³ª´«´Ù.
array split
(string pattern, string string, int [limit]);
Returns an array of strings, each of which is a substring of string formed by splitting it on boundaries formed by pattern. If an error occurs, returns false.
To get the first five fields from a line from /etc/passwd:
Example 1. split() example $passwd_list = split( ":", $passwd_line, 5 ); |
Note that pattern is case-sensitive.
See also explode() and implode().
sql_regcase -- ´ë,¼Ò¹®ÀÚ °¡¸®Áö ¾Ê´Â °Ë»ç¸¦ À§ÇÑ regular expressionÀ» ¸¸µç´Ù.
string sql_regcase(string string);
Returns a valid regular expression which will match string, ignoring case. This expression is string with each character converted to a bracket expression; this bracket expression contains that character's uppercase and lowercase form if applicable, otherwise it contains the original character twice.
Example 1. sql_regcase() example echo sql_regcase( "Foo bar" ); |
prints
[Ff][Oo][Oo][ ][Bb][Aa][Rr]
.
This can be used to achieve case insensitive pattern matching in products which support only case sensitive regular expressions.

sem_get -- semaphore id¸¦ ¾ò´Â´Ù.
int sem_get
(int key, int [max_acquire], int [perm]);
Returns: A positive semaphore identifier on success, or false on error.
sem_get() returns an id that can be used to access the System V semaphore with the given key. The semaphore is created if necessary using the permission bits specified in perm (defaults to 0666). The number of processes that can acquire the semaphore simultaneously is set to max_acquire (defaults to 1). Actually this value is set only if the process finds it is the only process currently attached to the semaphore.
A second call to sem_get() for the same key will return a different semaphore identifier, but both identifiers access the same underlying semaphore.
See also: sem_acquire() and sem_release().
sem_acquire -- semaphore¸¦ ¾ò´Â´Ù.
int sem_acquire
(int sem_identifier);
Returns: true on success, false on error
sem_acquire() blocks (if necessary) until the semaphore can be acquired. A process attempting to acquire a semaphore which it has already acquired will block forever if acquiring the semaphore would cause its max_acquire value to be exceeded.
After processing a request, any semaphores acquired by the process but not explicitly released will be released automatically and a warning will be generated.
See also: sem_get() and sem_release().
sem_release -- semaphore¸¦ Ç®¾îÁØ´Ù.
int sem_release
(int sem_identifier);
Returns: true on success, false on error
sem_release() releases the semaphore if it is currently acquired by the calling process, otherwise a warning is generated.
After releasing the semaphore, sem_acquire() may be called to re-acquire it.
See also: sem_get() and sem_acquire().
shm_attach -- °øÀ¯ ¸Þ¸ð¸®ÀÇ segment¸¦ ¸¸µé°Å³ª ¿¬´Ù.
int shm_attach
(int key, int [memsize], int [perm]);
shm_attach() returns an id that that can be used to access the System V shared memory with the given key, the first call creates the shared memory segment with mem_size (default: sysvshm.init_mem in php3.ini, otherwise 10000 bytes) and the optional perm-bits (default: 666).
A second call to shm_attach() for the same key will return a different shared memory identifier, but both identifiers access the same underlying shared memory. memsize and perm will be ignored.
shm_detach -- Disconnects from shared memory segment
int shm_detach
(int shm_identifier);
shm_detach() disconnects from the shared memory given by the shm_identifier created by shm_attach(). Remember, that shared memory still exist in the Unix system and the data is still present.
shm_get_var -- Returns a variable from shared memory
mixed shm_get_var
(int id, int variable_key);
shm_get_var() returns the variable with a given variable_key. The variable is still present in the shared memory.
shm_put_var -- Inserts or updates a variable in shared memory
int shm_put_var
(int shm_identifier, int variable_key, mixed variable);
Inserts or updates a variable with a given variable_key. All variable-types (double, int, string, array) are supported.
shm_remove -- Removes shared memory from Unix systems
int shm_remove
(int shm_identifier);
Removes shared memory from Unix systems. All data will be destroyed.
shm_remove_var -- Removes a variable from shared memory
int shm_remove_var
(int id, int variable_key);
Removes a variable with a given variable_key and frees the occupied memory.

snmpget -- SNMP object¸¦ °¡Á®¿Â´Ù.
int snmpget(string hostname, string community, string object_id);
Returns SNMP object value on success and false on error.
The snmpget() function is used to read the value of an SNMP object specified by the object_id. SNMP agent is specified by the hostname and the read community is specified by the community parameter.
snmpget("127.0.0.1", "public", "system.SysContact.0")
snmpwalk -- agent·Î ºÎÅÍ ¸ðµç SNMP objectµéÀ» °¡Á®¿Â´Ù.
int snmpwalk(int hostname, string community, string object_id);
Returns an array of SNMP object values starting from the object_id as root and false on error.
snmpwalk() function is used to read all the values from an SNMP agent specified by the hostname. Community specifies the read community for that agent. A null object_id is taken as the root of the SNMP objects tree and all objects under that tree are returned as an array. If object_id is specified, all the SNMP objects below that object_id are returned.
$a = snmpwalk("127.0.0.1", "public", "");
Above function call would return all the SNMP objects from the SNMP agent running on localhost. One can step through the values with a loop

This function complements ord(). See also sprintf() with a format string of %c.
chunk_split -- ¹®ÀÚ¿À» ºñ½ÁÇÑ Å©±â·Î ³ª´«´Ù.
string chunk_split
(string string, int [chunklen] , string [end] );
Can be used to split a string into smaller chunks which is useful for e.g. converting base64_encode output to match RFC 2045 behaviour. It inserts every chunklen (defaults to 76) chars the string end (defaults to "\r\n"). It returns the new string leaving the original string untouched.
Example 1. chr_replace() example

This function is significantly faster than ereg_replace().
convert_cyr_string -- ¹®ÀÚ¿À» ƯÁ¤ Cyrillic ¹®ÀÚ¿¡¼ ´Ù¸¥ °ÍÀ¸·Î ¹Ù²Û´Ù.
string convert_cyr_string
(string str, string from, string to);
This function converts the given string from one Cyrillic character set to another. The from and to arguments are single characters that represent the source and target Cyrillic character sets. The supported types are:
k - koi8-r
w - windows-1251
i - iso8859-5
a - x-cp866
d - x-cp866
m - x-mac-cyrillic
crypt -- ¹®ÀÚ¿À» DES encryption¹æ¹ýÀ¸·Î º¯È¯(encrypt)ÇÑ´Ù.
string crypt
(string str, string [salt]);
crypt() will encrypt a string using the standard Unix DES encryption method. Arguments are a string to be encrypted and an optional two-character salt string to base the encryption on. See the Unix man page for your crypt function for more information.
If the salt argument is not provided, it will be randomly generated by PHP.
Some operating systems support more than one type of encryption. In fact, sometimes the standard DES encryption is replaced by an MD5 based encryption algorithm. The encryption type is triggered by the salt argument. At install time, PHP determines the capabilities of the crypt function and will accept salts for other encryption types. If no salt is provided, PHP will auto-generate a standard 2-character DES salt by default unless the default encryption type on the system is MD5 in which case a random MD5-compatible salt is generated.
The standard DES encryption crypt() contains the salt as the first two characters of the output.
There is no decrypt function, since crypt() uses a one-way algorithm.
echo -- Çϳª ÀÌ»óÀÇ ¹®ÀÚ¿À» Ãâ·ÂÇÑ´Ù.
echo
(string arg1, string [argn]...);
Outputs all parameters.
echo() is not actually a function (it is a language construct) so you are not required to use parantheses with it.

See also: print() printf() flush()
explode -- ¹®ÀÚ¿À» ¹®ÀÚ¿ ±âÁØÀ¸·Î ³ª´«´Ù.
array explode(string separator, string string);
Returns an array of strings containing the elements separated by separator.
Example 1. explode() example $pizza = "piece1 piece2 piece3 piece4 piece5 piece6"; $pieces = explode(" ", $pizza); |
See also split() and implode().
flush -- output buffer¸¦ FlushÇÑ´Ù.
void flush(void);
Flushes the output buffers of PHP and whatever backend PHP is using (CGI, a web server, etc.) This effectively tries to push all the output so far to the user's browser.
get_meta_tags -- ÆÄÀÏ¿¡¼ ¸ðµç meta tagÀÇ content ¼Ó¼ºÀ» ÃßÃâÇÏ¿© ¹è¿¿¡ ÀúÀåÇÑ´Ù.
array get_meta_tags

Opens filename and parses it line by line for <meta> tags of the form
Example 1. Meta Tags Example
|
(pay attention to line endings - PHP3 uses a native function to parse the input, so a Mac file won't work on Unix).
The value of the name property becomes the key, the value of the content property becomes the value of the returned array, so you can easily use standard array functions to traverse it or access single values. Special characters in the value of the name property are substituted with '_', the rest is converted to lower case.
Setting use_include_path to 1 will result in PHP3 trying to open the file along the standard include path.
htmlspecialchars -- Ư¼ö¹®ÀÚµéÀ» HTML entity·Î º¯È¯ÇÑ´Ù.
string htmlspecialchars
(string string);
Certain characters have special significance in HTML, and should be represented by HTML entities if they are to preserve their meanings. This function returns a string with these conversions made.
This function is useful in preventing user-supplied text from containing HTML markup, such as in a message board or guest book application.
At present, the translations that are done are:
'&' (ampersand) becomes '&'
'"' (double quote) becomes '"'
'<' (less than) becomes '<'
'>' (greater than) becomes '>'
Note that this functions does not translate anything beyond what is listed above. For full entity translation, see htmlentities().
See also htmlentities() and nl2br().
htmlentities -- ¸ðµç °¡´ÉÇÑ ¹®ÀÚµéÀ» HTML entity·Î ¹Ù²Û´Ù.

rawurldecode -- URL-encoded ¹®ÀÚ¿À» decodeÇÑ´Ù.
string rawurldecode(string str);
Returns a string in which the sequences with percent (%) signs followed by two hex digits have been replaced with literal characters. For example, the string
foo%20bar%40baz
decodes into
foo bar@baz
See also rawurlencode().
rawurlencode -- RFC1738À» µû¶ó URL-encodeÇÑ´Ù.
string rawurlencode(string str);
Returns a string in which all non-alphanumeric characters except
-_.
have been replaced with a percent (%) sign followed by two hex digits. This is the encoding described in RFC1738 for protecting literal characters from being interpreted as special URL delimiters, and for protecting URL's from being mangled by transmission media with character conversions (like some email systems). For example, if you want to include a password in an ftp url:
Example 1. rawurlencode() example 1 echo '<A HREF="ftp://user:', rawurlencode ('foo @+%/'), '@ftp.my.com/x.txt">'; |
Or, if you pass information in a path info component of the url:
Example 2. rawurlencode() example 2 echo '<A HREF="http://x.com/department_list_script/', rawurlencode ('sales and marketing/Miami'), '">'; |
See also rawurldecode().
setlocale -- locale informationÀ» ¼³Á¤ÇÑ´Ù.
string setlocale
(string category, string locale);
category is a string specifying the category of the functions affected by the locale setting:
LC_ALL for all of the below
LC_COLLATE for string comparison - not currently implemented in PHP
LC_CTYPE for character classification and conversion, for example strtoupper()
LC_MONETARY for localeconv() - not currently implemented in PHP
LC_NUMERIC for decimal separator
LC_TIME for date and time formatting with strftime()
If locale is the empty string "", the locale names will be set from the values of environment variables with the same names as the above categories, or from "LANG".
If locale is zero or "0", the locale setting is not affected, only the current setting is returned.
Setlocale returns the new current locale, or false if the locale functionality is not implemented in the plattform, the specified locale does not exist or the category name is invalid. An invalid category name also causes a warning message.
similar_text -- µÎ ¹®ÀÚ¿ °£ÀÇ ºñ½ÁÇÑ Á¤µµ¸¦ °è»êÇÑ´Ù.
int similar_text
(string first, string second, double [percent]);
This calculates the similarity between two strings as described in Oliver [1993]. Note that this implementation does not use a stack as in Oliver's pseudo code, but recursive calls which may or may not speed up the whole process. Note also that the complexity of this algorithm is O(N**3) where N is the length of the longest string.
By passing a reference as third argument, similar_text() will calculate the similarity in percent for you. It returns the number of matching chars in both strings.
soundex -- ¹®ÀÚ¿ÀÇ soundex key¸¦ ±¸ÇÑ´Ù.(¿ªÀÚÁÖ: ºñ½ÁÇÑ ¹ßÀ½À» ã±â À§ÇØ »ç¿ë, ¿µ¾î¸¸ °¡´É)
string soundex
(string str);
Calculates the soundex key of str.
Soundex keys have the property that words pronounced similarly produce the same soundex key, and can thus be used to simplify searches in databases where you know the pronunciation but not the spelling. This soundex function returns a string 4 characters long, starting with a letter.
This particular soundex function is one described by Donald Knuth in "The Art Of Computer Programming, vol. 3: Sorting And Searching", Addison-Wesley (1973), pp. 391-392.
Example 1. Soundex Examples

sprintf -- formatµÈ ¹®ÀÚ¿À» ¹ÝȯÇÑ´Ù.
sprintf
(string format, mixed [args]...);
Returns a string produced according to the formatting string format.
The format string is composed by zero or more directives: ordinary characters (excluding %) that are copied directly to the result, and conversion specifications, each of which results in fetching its own parameter. This applies to both sprintf() and printf()
Each conversion specification consists of these elements, in order:
An optional padding specifier that says what character will be used for padding the results to the right string size. This may be a space character or a 0 (zero character). The default is to pad with spaces. An alternate padding character can be specified by prefixing it with a single quote ('). See the examples below.
An optional alignment specifier that says if the result should be left-justified or right-justified. The default is right-justified; a - character here will make it left-justified.
An optional number, a width specifier that says how many characters (minimum) this conversion should result in.
An optional precision specifier that says how many decimal digits should be displayed for floating-point numbers. This option has no effect for other types than double. (Another function useful for formatting numbers is number_format().)
A type specifier that says what type the argument data should be treated as. Possible types:
% - a literal percent character. No argument is required. |
b - the argument is treated as an integer, and presented as a binary number. |
c - the argument is treated as an integer, and presented as the character with that ASCII value. |
d - the argument is treated as an integer, and presented as a decimal number. |
f - the argument is treated as a double, and presented as a floating-point number. |
o - the argument is treated as an integer, and presented as an octal number. |
s - the argument is treated as and presented as a string. |
x - the argument is treated as an integer and presented as a hexadecimal number (with lowercase letters). |
X - the argument is treated as an integer and presented as a hexadecimal number (with uppercase letters). |

string strrpos(string haystack, char needle);
Returns the numeric position of the last occurrence of needle in the haystack string. Note that the needle in this case can only be a single character. If a string is passed as the needle, then only the first character of that string will be used.
If needle is not found, returns false.
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
See also strpos(), strrchr(), substr(), and strstr().
strpos -- ÇØ´ç ¹®ÀÚ¿ÀÌ ³ªÅ¸³ª´Â ù À§Ä¡¸¦ ±¸ÇÑ´Ù.
int strpos
(string haystack, string needle, int [offset]);
Returns the numeric position of the first occurrence of needle in the haystack string. Unlike the strrpos(), this function can take a full string as the needle parameter and the entire string will be used.
If needle is not found, returns false.
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
The optional offset parameter allows you to specify which character in haystack to start searching. The position returned is still relative to the the beginning of haystack.
See also strrpos(), strrchr(), substr(), and strstr().
strrchr -- ¹®ÀÚ¿ÀÌ ¸¶Áö¸·À¸·Î ³ªÅ¸³ª´Â À§Ä¡¸¦ ±¸ÇÑ´Ù.
string strrchr

string strstr(string haystack, string needle);
Returns all of haystack from the first occurrence of needle to the end.
If needle is not found, returns false.
If needle is not a string, it is converted to an integer and applied as the ordinal value of a character.
See also strrchr(), substr(), and ereg().
strtok -- ¹®ÀÚ¿À» tokenÈ ÇÑ´Ù.
string strtok
(string arg1, string arg2);
strtok() is used to tokenize a string. That is, if you have a string like "This is an example string" you could tokenize this string into its individual words by using the space character as the token.
Example 1. strtok() example
|
Note that only the first call to strtok uses the string argument. Every subsequent call to strtok only needs the token to use, as it keeps track of where it is in the current string. To start over, or to tokenize a new string you simply call strtok with the string argument again to initialize it. Note that you may put multiple tokens in the token parameter. The string will be tokenized when any one of the characters in the argument are found.
Also be careful that your tokens may be equal to "0". This evaluates to false in conditional expressions.
See also split() and explode().
strtolower -- ¼Ò¹®ÀÚ·Î ¸¸µç´Ù.
string strtolower(string str);
Returns string with all alphabetic characters converted to lowercase.
Note that 'alphabetic' is determined by the current locale. This means that in i.e. the default "C" locale, characters such as umlaut-A (Ä) will not be converted.
See also strtoupper() and ucfirst().
strtoupper -- ´ë¹®ÀÚ·Î ¸¸µç´Ù.
string strtoupper(string string);
Returns string with all alphabetic characters converted to uppercase.
Note that 'alphabetic' is determined by the current locale. For instance, in the default "C" locale characters such as umlaut-a (ä) will not be converted.
See also strtolower() and ucfirst().
str_replace -- Replace all occurrences of needle in haystack with str
string str_replace
(string needle, string str, string haystack);
This function replaces all occurences of needle in haystack with the given str. If you don't need fancy replacing rules, you should always use this function instead of ereg_replace().
Example 1. str_replace() example
|
This function is binary safe.
See also ereg_replace().
strtr -- ƯÁ¤ ¹®ÀÚ¿À» ´ëÄ¡(translate)ÇÑ´Ù.
string strtr
(string str, string from, string to);
This function operates on str, translating all occurrences of each character in from to the corresponding character in to and returning the result.
If from and to are different lengths, the extra characters in the longer of the two are ignored.
Example 1. strtr() example
|
See also ereg_replace().
substr -- ¹®ÀÚ¿ÀÇ ÀϺκÐÀ» ¹ÝȯÇÑ´Ù.
string substr
(string string, int start, int [length]);
Substr returns the portion of string specified by the start and length parameters.
If start is positive, the returned string will start at the start'th character of string. Examples:
$rest = substr("abcdef", 1); // returns "bcdef"$rest = substr("abcdef", 1, 3); // returns "bcd"
If start is negative, the returned string will start at the start'th character from the end of string. Examples:
$rest = substr("abcdef", -1); // returns "f"$rest = substr("abcdef", -2); // returns "ef"$rest = substr("abcdef", -3, 1); // returns "d"
If length is given and is positive, the string returned will end length characters from start. If this would result in a string with negative length (because the start is past the end of the string), then the returned string will contain the single character at start.
If length is given and is negative, the string returned will end length characters from the end of string. If this would result in a string with negative length, then the returned string will contain the single character at start. Examples:
$rest = substr("abcdef", -1, -1); // returns "bcde"
See also strrchr() and ereg().
trim -- ¹®ÀÚ¿ÀÇ ¾Õ,µÚ ¿©¹é ¸ðµÎ¸¦ Á¦°ÅÇÑ´Ù.
string trim(string str);
This function strips whitespace from the start and the end of a string and returns the stripped string.
ucfirst -- ¹®ÀÚ¿ÀÇ Ã³À½ ¹®ÀÚ¸¦ ´ë¹®ÀÚ·Î ¸¸µç´Ù.
string ucfirst(string str);
Capitalizes the first character of str if that character is alphabetic.
Note that 'alphabetic' is determined by the current locale. For instance, in the default "C" locale characters such as umlaut-a (ä) will not be converted.
See also strtoupper() and strtolower().
ucwords -- Uppercase the first character of each word in a string
string ucwords
(string str);
Capitalizes the first character of each word in str if that character is alphabetic.
See also strtoupper(), strtolower() and ucfirst().
parse_url -- PHP°¡ form data¸¦ Çؼ®ÇϵíÀÌ query stringÀ» Çؼ®(parse)ÇÑ´Ù.
array parse_url
(string url);
This function returns an associative array returning any of the various components of the URL that are present. This includes the "scheme", "host", "port", "user", "pass", "path", "query", and "fragment".
urldecode -- URL-encodeµÈ ¹®ÀÚ¿À» decodeÇÑ´Ù.
string urldecode(string str);
Decodes any %## encoding in the given string. The decoded string is returned.
Example 1. urldecode() example $a = split ('&', $querystring); $i = 0; while ($i < count ($a)) { $b = split ('=', $a [$i]); echo 'Value for parameter ', htmlspecialchars (urldecode ($b [0])), ' is ', htmlspecialchars (urldecode ($b [1])), "<BR>"; $i++; } |
See also urlencode()
urlencode -- ¹®ÀÚ¿À» URL-encodeÇÑ´Ù.
string urlencode(string str);
Returns a string in which all non-alphanumeric characters except -_. have been replaced with a percent (%) sign followed by two hex digits and spaces encoded as plus (+) signs. It is encoded the same way that the posted data from a WWW form is encoded, that is the same way as in application/x-www-form-urlencoded media type. This differs from the RFC1738 encoding (see rawurlencode() ) in that for historical reasons, spaces are encoded as plus (+ ) signs. This function is convenient when encoding a string to be used in a query part of an URL, as a convinient way to pass variables to the next page:
Example 1. urlencode() example echo '<A HREF="mycgi?foo=', urlencode ($userinput), '">'; |
See also urldecode()
base64_encode -- base64 ¹æ½ÄÀ¸·Î encodeÇÑ´Ù.
string base64_encode(string data);
base64_encode() returns data encoded with base64. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies.
Base64-encoded data takes about 33% more space than the original data.
See also: base64_decode(), RFC-2045 section 6.8.
base64_decode -- base64·Î encodeµÈ ¹®ÀÚ¿À» decode ÇÑ´Ù.

ÀÌ ÇÔ¼öµéÀº WDDX¿Í ÇÔ²² µ¿ÀÛÇϵµ·Ï µÇ¾îÀÖ´Ù.
Note that all the functions that serialize variables use the first element of an array to determine whether the array is to be serialized into an array or structure. If the first element has string key, then it is serialized into a structure, otherwise, into an array.
Example 1. Serializing a single value
|
This example will produce:
<wddxPacket version='0.9'><header comment='PHP packet'/><data><string>PHP to WDDX packet example</string></data></wddxPacket>
Example 2. Using incremental packets
|
This example will produce:
<wddxPacket version='0.9'><header comment='PHP'/><data><struct><var name='pi'><number>3.1415926</number></var><var name='cities'><array length='3'><string>Austin</string><string>Novato</string><string>Seattle</string></array></var></struct></data></wddxPacket>
wddx_serialize_value -- WDDX ÆÐÄÏ¿¡ ´ÜÀÏ °ªÀ» serialize ÇÑ´Ù.
string wddx_serialize_value
(mixed var, string [comment]);
wddx_serialize_value() is used to create a WDDX packet from a single given value. It takes the value contained in var, and an optional comment string that appears in the packet header, and returns the WDDX packet.
wddx_serialize_vars -- WDDX ÆÐÄÏ¿¡ ¿©·¯ º¯¼ö¸¦ serialize ÇÑ´Ù.
string wddx_serialize_vars
(string var_name | array var_names [, ... ] );
wddx_serialize_vars() is used to create a WDDX packet with a structure that contains the serialized representation of the passed variables.
wddx_serialize_vars() takes a variable number of arguments, each of which can be either a string naming a variable or an array containing strings naming the variables or another array, etc.
Example 1. wddx_serialize_vars example
|
The above example will produce:
<wddxPacket version='0.9'><header/><data><struct><var name='a'><number>1</number></var><var name='b'><number>5.5</number></var><var name='c'><array length='3'><string>blue</string><string>orange</string><string>violet</string></array></var><var name='d'><string>colors</string></var></struct></data></wddxPacket>

int wddx_packet_start
(string [comment]);
Use wddx_packet_start() to start a new WDDX packet for incremental addition of variables. It takes an optional comment string and returns a packet ID for use in later functions. It automatically creates a structure definition inside the packet to contain the variables.
wddx_packet_end -- ÁöÁ¤µÈ IDÀÇ WDDX ÆÐÄÏÀ» Á¾·áÇÑ´Ù.
int wddx_packet_end
(int packet_id);
wddx_packet_end() ends the WDDX packet specified by the packet_id and returns the string with the packet.
wddx_add_vars -- ÇØ´çÇÏ´Â ÆÐÄÏ¿¡ Ãß°¡·Î º¯¼öµéÀ» serializeÇÑ´Ù.
wddx_add_vars
(int packet_id, ...);
wddx_add_vars() is used to serialize passed variables and add the result to the packet specified by the packet_id. The variables to be serialized are specified in exactly the same way as wddx_serialize_vars().
wddx_deserialize -- WDDX ÆÐÄÏÀ» deserialize ÇÑ´Ù.
mixed wddx_deserialize
(string packet);
wddx_deserialized() takes a packet string and deserializes it. It returns the result which can be string, number, or array. Note that structures are deserialized into associative arrays.

The gz-file pointer must be valid, and must point to a file successfully opened by gzopen().
gzeof -- gz-file pointer°¡ end-of-file¿¡ Àִ°¡ °Ë»çÇÑ´Ù.
int gzeof(int zp);
Returns true if the gz-file pointer is at EOF or an error occurs; otherwise returns false.
The gz-file pointer must be valid, and must point to a file successfully opened by gzopen().
gzfile -- gz-fileÀÇ ³»¿ëÀ» ¹è¿·Î Àд´Ù.

Identical to readgzfile(), except that gzfile() returns the file in an array.
See also readgzfile(), and gzopen().
gzgetc -- gz-file pointer¿¡¼ ÇÑ ¹®ÀÚ¸¦ Àд´Ù.
string gzgetc(int zp);
Returns a string containing a single (uncompressed) character read from the file pointed to by zp. Returns FALSE on EOF (as does gzeof()).
The gz-file pointer must be valid, and must point to a file successfully opened by gzopen().
See also gzopen(), and gzgets().
gzgets -- gz-file pointer¿¡¼ ÇÑ ÁÙÀ» Àд´Ù.
string gzgets(int zp, int length);
Returns a (uncompressed) string of up to length - 1 bytes read from the file pointed to by fp. Reading ends when length - 1 bytes have been read, on a newline, or on EOF (whichever comes first).
If an error occurs, returns false.
The file pointer must be valid, and must point to a file successfully opened by gzopen().
See also gzopen(), and gzgetc().
gzgetss -- gz-file pointer¿¡¼ ÇÑ ÁÙÀ» Àоî HTML tagµéÀ» stripÇÑ´Ù.
string gzgetss(int zp, int length);
Identical to gzgets(), except that gzgetss attempts to strip any HTML and PHP tags from the text it reads.
See also gzgets(), and gzopen().
gzopen -- gz-fileÀ» ¿¬´Ù.
int gzopen(string filename, string mode);
Opens a gzip (.gz) file for reading or writing. The mode parameter is as in fopen() ("rb" or "wb") but can also include a compression level ("wb9") or a strategy: 'f' for filtered data as in "wb6f", 'h' for Huffman only compression as in "wb1h". (See the description of deflateInit2 in zlib.h for more information about the strategy parameter.)
Gzopen can be used to read a file which is not in gzip format; in this case gzread will directly read from the file without decompression.
Gzopen returns a file pointer to the file opened, after that, everything you read from this file descriptor will be transparently decompressed and what you write gets compressed.
If the open fails, the function returns false.
Example 1. gzopen() example $fp = gzopen("/tmp/file.gz", "r"); |
See also gzclose().
gzpassthru -- gz-file pointer¿¡¼ºÎÅÍ µÚ¿¡ ³²¾ÆÀÖ´Â ¸ðµç µ¥ÀÌŸ¸¦ Ãâ·Â(output)ÇÑ´Ù.
int gzpassthru(int zp);
Reads to EOF on the given gz-file pointer and writes the (uncompressed) results to standard output.
If an error occurs, returns false.
The file pointer must be valid, and must point to a file successfully opened by gzopen().
The gz-file is closed when gzpassthru() is done reading it (leaving zp useless).
gzputs -- gz-file pointer¿¡ ¾´´Ù.
int gzputs
(int zp, string str, int [length]);
gzputs() is an alias to gzwrite(), and is identical in every way.
gzread -- gz-file¿¡¼ ÀÌÁø µ¥ÀÌŸ·Î Àд´Ù.
string gzread(int zp, int length);
gzread() reads up to length bytes from the gz-file pointer referenced by zp. Reading stops when length (uncompressed) bytes have been read or EOF is reached, whichever comes first.
// get contents of a gz-file into a string $filename = "/usr/local/something.txt.gz"; $zd = gzopen( $filename, "r" ); $contents = gzread( $zd, 10000 ); gzclose( $zd );
See also gzwrite(), gzopen(), gzgets(), gzgetss(), gzfile(), and gzpassthru().
gzrewind -- gz-file pointerÀÇ À§Ä¡¸¦ ¸Ç ¾ÕÀ¸·Î °¡Á®°£´Ù.
int gzrewind(int zp);
Sets the file position indicator for zp to the beginning of the file stream.
If an error occurs, returns 0.
The file pointer must be valid, and must point to a file successfully opened by gzopen().
See also gzseek() and gztell().
gzseek -- gz-file pointer¸¦ ¿Å±ä´Ù.
int gzseek(int zp, int offset);
Sets the file position indicator for the file referenced by zp to offset bytes into the file stream. Equivalent to calling (in C) gzseek( zp, offset, SEEK_SET ).
If the file is opened for reading, this function is emulated but can be extremely slow. If the file is opened for writing, only forward seeks are supported; gzseek then compresses a sequence of zeroes up to the new starting position.
Upon success, returns 0; otherwise, returns -1. Note that seeking past EOF is not considered an error.
See also gztell() and gzrewind().
gztell -- gz-file pointerÀÇ Àаí, ¾µ À§Ä¡¸¦ ¹ÝȯÇÑ´Ù.
int gztell(int zp);
Returns the position of the file pointer referenced by zp; i.e., its offset into the file stream.
If an error occurs, returns false.
The file pointer must be valid, and must point to a file successfully opened by gzopen().
See also gzopen(), gzseek() and gzrewind().
readgzfile -- gz-fileÀ» Ãâ·Â(output)ÇÑ´Ù.
int readgzfile(string filename);
Reads a file, decompresses it and writes it to standard output.
Returns the number of (uncompressed) bytes read from the file. If an error occurs, false is returned and unless the function was called as @readgzfile, an error message is printed.
The file filename will be opened from the filesystem and its contents written to standard output.
See also gzpassthru(), gzfile(), and gzopen().
gzwrite -- gz-file¿¡ ÀÌÁø µ¥ÀÌŸ¸¦ ¾´´Ù.
int gzwrite
(int zp, string string, int [length]);
gzwrite() writes the contents of string to the gz-file stream pointed to by zp. If the length argument is given, writing will stop after length (uncompressed) bytes have been written or the end of string is reached, whichever comes first.
Note that if the length argument is given, then the magic_quotes_runtime configuration option will be ignored and no slashes will be stripped from string.

Table 1. Supported XML handlers
PHP function to set handler |
Event description |
---|---|
Element events are issued whenever the XML parser encounters start or end tags. There are separate handlers for start tags and end tags. |
|
Character data is roughly all the non-markup contents of XML documents, including whitespace between tags. Note that the XML parser does not add or remove any whitespace, it is up to the application (you) to decide whether whitespace is significant. |
|
PHP programmers should be familiar with processing instructions (PIs) already. <?php ?> is a processing instruction, where php is called the "PI target". The handling of these are application-specific, except that all PI targets starting with "XML" are reserved. |
|
What goes not to another handler goes to the default handler. You will get things like the XML and document type declarations in the default handler. |
|
This handler will be called for declaration of an unparsed (NDATA) entity. |
|
This handler is called for declaration of a notation. |
|
This handler is called when the XML parser finds a reference to an external parsed general entity. This can be a reference to a file or URL, for example. See the external entity example for a demonstration. |

This function creates an XML parser and returns a handle for use by other XML functions. Returns false on failure.
xml_set_element_handler -- ½ÃÀÛ element handlers¿Í ³¡ element handlers¸¦ ¼³Á¤ÇÑ´Ù.
int xml_set_element_handler
(int parser, string startElementHandler, string endElementHandler);
Sets the element handler functions for the XML parser parser. startElementHandler and endElementHandler are strings containing the names of functions that must exist when xml_parse() is called for parser.
The function named by startElementHandler must accept three parameters:
startElementHandler
(int parser, string name, string attribs);
The function named by endElementHandler must accept two parameters:
endElementHandler
(int parser, string name);
If a handler function is set to an empty string, or false, the handler in question is disabled.
True is returned if the handlers are set up, false if parser is not a parser.
There is currently no support for object/method handlers.
xml_set_character_data_handler -- character data handler¸¦ ¼³Á¤ÇÑ´Ù.
int xml_set_character_data_handler
(int parser, string handler);
Sets the character data handler function for the XML parser parser. handler is a string containing the name of a function that must exist when xml_parse() is called for parser.
The function named by handler must accept two parameters:
handler
(int parser, string data);
If a handler function is set to an empty string, or false, the handler in question is disabled.
True is returned if the handler is set up, false if parser is not a parser.

xml_set_processing_instruction_handler -- processing instruction (PI) handler¸¦ ¼³Á¤ÇÑ´Ù.
int xml_set_processing_instruction_handler
(int parser, string handler);
Sets the processing instruction (PI) handler function for the XML parser parser. handler is a string containing the name of a function that must exist when xml_parse() is called for parser.
A processing instruction has the following format:
<?target data?>
You can put PHP code into such a tag, but be aware of one limitation: in an XML PI, the PI end tag (?>) can not be quoted, so this character sequence should not appear in the PHP code you embed with PIs in XML documents. If it does, the rest of the PHP code, as well as the "real" PI end tag, will be treated as character data.
The function named by handler must accept three parameters:
handler
(int parser, string target, string data);
If a handler function is set to an empty string, or false, the handler in question is disabled.
True is returned if the handler is set up, false if parser is not a parser.
There is currently no support for object/method handlers.
xml_set_default_handler -- ±âº» handler¸¦ ¼³Á¤ÇÑ´Ù.
int xml_set_default_handler
(int parser, string handler);
Sets the default handler function for the XML parser parser. handler is a string containing the name of a function that must exist when xml_parse() is called for parser.
The function named by handler must accept two parameters:
handler
(int parser, string data);
If a handler function is set to an empty string, or false, the handler in question is disabled.
True is returned if the handler is set up, false if parser is not a parser.
There is currently no support for object/method handlers.
xml_set_unparsed_entity_decl_handler -- unparsed entity declaration handler¸¦ ¼³Á¤ÇÑ´Ù.
int xml_set_unparsed_entity_decl_handler
(int parser, string handler);
Sets the unparsed entity declaration handler function for the XML parser parser. handler is a string containing the name of a function that must exist when xml_parse() is called for parser.
This handler will be called if the XML parser encounters an external entity declaration with an NDATA declaration, like the following:
<!ENTITY name {publicId | systemId} NDATA notationName>
See section 4.2.2 of the XML 1.0 spec for the definition of notation declared external entities.
The function named by handler must accept six parameters:
handler
(int parser, string entityName, string base, string systemId, string publicId, string notationName);
If a handler function is set to an empty string, or false, the handler in question is disabled.
True is returned if the handler is set up, false if parser is not a parser.
There is currently no support for object/method handlers.
xml_set_notation_decl_handler -- notation declaration handler¸¦ ¼³Á¤ÇÑ´Ù.
int xml_set_notation_decl_handler
(int parser, string handler);
Sets the notation declaration handler function for the XML parser parser. handler is a string containing the name of a function that must exist when xml_parse() is called for parser.
A notation declaration is part of the document's DTD and has the following format:
<!NOTATION name {systemId | publicId}>
See section 4.7 of the XML 1.0 spec for the definition of notation declarations.
The function named by handler must accept five parameters:
handler
(int parser, string notationName, string base, string systemId, string publicId);
If a handler function is set to an empty string, or false, the handler in question is disabled.
True is returned if the handler is set up, false if parser is not a parser.
There is currently no support for object/method handlers.
xml_set_external_entity_ref_handler -- external entity reference handler¸¦ ¼³Á¤ÇÑ´Ù.
int xml_set_external_entity_ref_handler
(int parser, string handler);
Sets the notation declaration handler function for the XML parser parser. handler is a string containing the name of a function that must exist when xml_parse() is called for parser.
The function named by handler must accept five parameters, and should return an integer value. If the value returned from the handler is false (which it will be if no value is returned), the XML parser will stop parsing and xml_get_error_code() will return XML_ERROR_EXTERNAL_ENTITY_HANDLING.
int
handler
(int parser, string openEntityNames, string base, string systemId, string publicId);
If a handler function is set to an empty string, or false, the handler in question is disabled.
True is returned if the handler is set up, false if parser is not a parser.
There is currently no support for object/method handlers.
xml_parse -- XML documentÀÇ Çؼ®(parsing)À» ½ÃÀÛÇÑ´Ù.
int xml_parse
(int parser, string data, int [isFinal]);
When the XML document is parsed, the handlers for the configured events are called as many times as necessary, after which this function returns true or false.
True is returned if the parse was successful, false if it was not successful, or if parser does not refer to a valid parser. For unsuccessful parses, error information can be retrieved with xml_get_error_code(), xml_error_string(), xml_get_current_line_number(), xml_get_current_column_number() and xml_get_current_byte_index().
xml_get_error_code -- XML parser error code¸¦ ¾ò´Â´Ù.

This function decodes data, assumed to be UTF-8 encoded, to ISO-8859-1.
See utf8_encode() for an explaination of UTF-8 encoding.
utf8_encode -- ISO-8859-1·Î encodeµÈ ¹®ÀÚ¿À» UTF-8À¸·Î º¯È¯ÇÑ´Ù.
string utf8_encode
(string data);
This function encodes the string data to UTF-8, and returns the encoded version. UTF-8 is a standard mechanism used by Unicodefor encoding wide character values into a byte stream. UTF-8 is transparent to plain ASCII characters, is self-synchronized (meaning it is possible for a program to figure out where in the bytestream characters start) and can be used with normal string comparison functions for sorting and such. PHP encodes UTF-8 characters in up to four bytes, like this:

PHP 3.0 is rewritten from the ground up. It has a proper parser that is much more robust and consistent than 2.0's. 3.0 is also significantly faster, and uses less memory. However, some of these improvements have not been possible without compatibility changes, both in syntax and functionality.
In addition, PHP's developers have tried to clean up both PHP's syntax and semantics in version 3.0, and this has also caused some incompatibilities. In the long run, we believe that these changes are for the better.
This chapter will try to guide you through the incompatibilities you might run into when going from PHP/FI 2.0 to PHP 3.0 and help you resolve them. New features are not mentioned here unless necessary.
A conversion program that can automatically convert your old PHP/FI 2.0 scripts exists. It can be found in the convertor subdirectory of the PHP 3.0 distribution. This program only catches the syntax changes though, so you should read this chapter carefully anyway.
The first thing you probably will notice is that PHP's start and end tags have changed. The old <? > form has been replaced by three new possible forms:
Example 0-1. Migration: old start/end tags
|
As of version 2.0, PHP/FI also supports this variation:
Example 0-2. Migration: first new start/end tags
|
Notice that the end tag now consists of a question mark and a greater-than character instead of just greater-than. However, if you plan on using XML on your server, you will get problems with the first new variant, because PHP may try to execute the XML markup in XML documents as PHP code. Because of this, the following variation was introduced:
Example 0-3. Migration: second new start/end tags
|
Some people have had problems with editors that don't understand the processing instruction tags at all. Microsoft FrontPage is one such editor, and as a workaround for these, the following variation was introduced as well:
Example 0-4. Migration: third new start/end tags
|
The `alternative' way to write if/elseif/else statements, using if(); elseif(); else; endif; cannot be efficiently implemented without adding a large amount of complexity to the 3.0 parser. Because of this, the syntax has been changed:
Example 0-5. Migration: old if..endif syntax
|
Example 0-6. Migration: new if..endif syntax
|
Notice that the semicolons have been replaced by colons in all statements but the one terminating the expression (endif).
Just like with if..endif, the syntax of while..endwhile has changed as well:
Example 0-7. Migration: old while..endwhile syntax
|
Example 0-8. Migration: new while..endwhile syntax
|
Warning |
If you use the old while..endwhile syntax in PHP 3.0, you will get a never-ending loop. |
PHP/FI 2.0 used the left side of expressions to determine what type the result should be. PHP 3.0 takes both sides into account when determining result types, and this may cause 2.0 scripts to behave unexpectedly in 3.0.
Consider this example:
$a[0]=5;$a[1]=7;$key = key($a);while ("" != $key) {echo "$keyn";next($a);}
In PHP/FI 2.0, this would display both of $a's indices. In PHP 3.0, it wouldn't display anything. The reason is that in PHP 2.0, because the left argument's type was string, a string comparison was made, and indeed "" does not equal "0", and the loop went through. In PHP 3.0, when a string is compared with an integer, an integer comparison is made (the string is converted to an integer). This results in comparing atoi("") which is 0, and variablelist which is also 0, and since 0==0, the loop doesn't go through even once.
The fix for this is simple. Replace the while statement with:
while ((string)$key != "") {
PHP 3.0's error messages are usually more accurate than 2.0's were, but you no longer get to see the code fragment causing the error. You will be supplied with a file name and a line number for the error, though.
In PHP 3.0 boolean evaluation is short-circuited. This means that in an expression like (1 || test_me()), the function test_me() would not be executed since nothing can change the result of the expression after the 1.
This is a minor compatibility issue, but may cause unexpected side-effects.
Most internal functions have been rewritten so they return TRUE when successful and FALSE when failing, as opposed to 0 and -1 in PHP/FI 2.0, respectively. The new behaviour allows for more logical code, like $fp = fopen("/your/file") or fail("darn!");. Because PHP/FI 2.0 had no clear rules for what functions should return when they failed, most such scripts will probably have to be checked manually after using the 2.0 to 3.0 convertor.
Example 0-9. Migration from 2.0: return values, old code
|
Example 0-10. Migration from 2.0: return values, new code
|
The PHP 3.0 Apache module no longer supports Apache versions prior to 1.2. Apache 1.2 or later is required.
echo() no longer supports a format string. Use the printf() function instead.
In PHP/FI 2.0, an implementation side-effect caused $foo[0] to have the same effect as $foo. This is not true for PHP 3.0.
Reading arrays with $array[] is no longer supported
That is, you cannot traverse an array by having a loop that does $data = $array[]. Use current() and next() instead.
Also, $array1[] = $array2 does not append the values of $array2 to $array1, but appends $array2 as the last entry of $array1. See also multidimensional array support.
"+" is no longer overloaded as a concatenation operator for strings, instead it converts it's arguments to numbers and performs numeric addition. Use "." instead.
Example 0-11. Migration from 2.0: concatenation for strings
In PHP 2.0 this would echo 11, in PHP 3.0 it would echo 2. Instead use:
This would echo 2 in both PHP 2.0 and 3.0.
This will echo 11 in PHP 3.0. |

When you change any of the passed parameters, whether they are sent by reference or by value, you can either start over with the parameter by calling pval_destructor on it, or if it's an ARRAY you want to add to, you can use functions similar to the ones in internal_functions.h which manipulate return_value as an ARRAY.
Also if you change a parameter to IS_STRING make sure you first assign the new estrdup()'ed string and the string length, and only later change the type to IS_STRING. If you change the string of a parameter which already IS_STRING or IS_ARRAY you should run pval_destructor on it first.
A function can take a variable number of arguments. If your function can take either 2 or 3 arguments, use the following:

If you get an argument of one type and would like to use it as another, or if you just want to force the argument to be of a certain type, you can use one of the following conversion functions:
convert_to_long(arg1);convert_to_double(arg1);convert_to_string(arg1);convert_to_boolean_long(arg1); /* If the string is "" or "0" it becomes 0, 1 otherwise */convert_string_to_number(arg1); /* Converts string to either LONG or DOUBLE depending on string */
These function all do in-place conversion. They do not return anything.
The actual argument is stored in a union; the members are:

The following examples use 'active_symbol_table'. You should replace it with &symbol_table if you specifically want to work with the 'main' symbol table. Also, the same functions may be applied to arrays, as explained below.
Example 0-3. Checking whether $foo exists in a symbol table
|
Example 0-4. Finding a variable's size in a symbol table
|
Arrays in PHP 3.0 are implemented using the same hashtables as symbol tables. This means the two above functions can also be used to check variables inside arrays.
If you want to define a new array in a symbol table, you should do the following.
First, you may want to check whether it exists and abort appropiately, using hash_exists() or hash_find().
Next, initialize the array:
Example 0-5. Initializing a new array
|
This code declares a new array, named $foo, in the active symbol table. This array is empty.
Here's how to add new entries to it:
Example 0-6. Adding entries to a new array
|
If you'd like to modify a value that you inserted to a hash, you must first retrieve it from the hash. To prevent that overhead, you can supply a pval ** to the hash add function, and it'll be updated with the pval * address of the inserted element inside the hash. If that value is NULL (like in all of the above examples) - that parameter is ignored.
hash_next_index_insert() uses more or less the same logic as "$foo[] = bar;" in PHP 2.0.
If you are building an array to return from a function, you can initialize the array just like above by doing:
if (array_init(return_value) == FAILURE) { failed...; }
...and then adding values with the helper functions:
add_next_index_long(return_value,long_value);add_next_index_double(return_value,double_value);add_next_index_string(return_value,estrdup(string_value));
Of course, if the adding isn't done right after the array initialization, you'd probably have to look for the array first:
pval *arr;if (hash_find(active_symbol_table,"foo",sizeof("foo"),(void **)&arr)==FAILURE) { can't find... }else { use arr->value.ht... }
Note that hash_find receives a pointer to a pval pointer, and not a pval pointer.
Just about any hash function returns SUCCESS or FAILURE (except for hash_exists(), which returns a boolean truth value).

The string macros above will all estrdup() the passed 's' argument, so you can safely free the argument after calling the macro, or alternatively use statically allocated memory.

Returning an object:
Call object_init(return_value).
Fill it up with values. The functions available for this purpose are listed below.
Possibly, register functions for this object. In order to obtain values from the object, the function would have to fetch "this" from the active_symbol_table. Its type should be IS_OBJECT, and it's basically a regular hash table (i.e., you can use regular hash functions on .value.ht). The actual registration of the function can be done using:
add_method( return_value, function_name, function_ptr );
The functions used to populate an object are:
add_property_long( return_value, property_name, l ) - Add a property named 'property_name', of type long, equal to 'l'
add_property_double( return_value, property_name, d ) - Same, only adds a double
add_property_string( return_value, property_name, str ) - Same, only adds a string
add_property_stringl( return_value, property_name, str, l ) - Same, only adds a string of length 'l'
Returning an array:
Call array_init(return_value).
Fill it up with values. The functions available for this purpose are listed below.
The functions used to populate an array are:
add_assoc_long(return_value,key,l) - add associative entry with key 'key' and long value 'l'
add_assoc_double(return_value,key,d)
add_assoc_string(return_value,key,str)
add_assoc_stringl(return_value,key,str,length) specify the string length
add_index_long(return_value,index,l) - add entry in index 'index' with long value 'l'
add_index_double(return_value,index,d)
add_index_string(return_value,index,str)
add_index_stringl(return_value,index,str,length) - specify the string length
add_next_index_long(return_value,l) - add an array entry in the next free offset with long value 'l'
add_next_index_double(return_value,d)
add_next_index_string(return_value,str)
add_next_index_stringl(return_value,str,length) - specify the string length

Available functions:
php3_list_insert(ptr, type) - returns the 'id' of the newly inserted resource
php3_list_delete(id) - delete the resource with the specified id
php3_list_find(id,*type) - returns the pointer of the resource with the specified id, updates 'type' to the resource's type
Typically, these functions are used for SQL drivers but they can be used for anything else; for instance, maintaining file descriptors.
Typical list code would look like this:
Example 0-7. Adding a new resource
|
Example 0-8. Using an existing resource
|
Example 0-9. Deleting an existing resource
|
The resource types should be registered in php3_list.h, in enum list_entry_type. In addition, one should add shutdown code for any new resource type defined, in list.c's list_entry_destructor() (even if you don't have anything to do on shutdown, you must add an empty case).

persistence ¸ðµâÀÇ ÀϹÝÀûÀÎ idea´Â ´ÙÀ½°ú °°´Ù. :
Code all of your module to work with the regular resource list mentioned in section (9).
Code extra connect functions that check if the resource already exists in the persistent resource list. If it does, register it as in the regular resource list as a pointer to the persistent resource list (because of 1., the rest of the code should work immediately). If it doesn't, then create it, add it to the persistent resource list AND add a pointer to it from the regular resource list, so all of the code would work since it's in the regular resource list, but on the next connect, the resource would be found in the persistent resource list and be used without having to recreate it. You should register these resources with a different type (e.g. LE_MYSQL_LINK for non-persistent link and LE_MYSQL_PLINK for a persistent link).
If you read mysql.c, you'll notice that except for the more complex connect function, nothing in the rest of the module has to be changed.
The very same interface exists for the regular resource list and the persistent resource list, only 'list' is replaced with 'plist':
php3_plist_insert(ptr, type) - returns the 'id' of the newly inserted resource
php3_plist_delete(id) - delete the resource with the specified id
php3_plist_find(id,*type) - returns the pointer of the resource with the specified id, updates 'type' to the resource's type
However, it's more than likely that these functions would prove to be useless for you when trying to implement a persistent module. Typically, one would want to use the fact that the persistent resource list is really a hash table. For instance, in the MySQL/mSQL modules, when there's a pconnect() call (persistent connect), the function builds a string out of the host/user/passwd that were passed to the function, and hashes the SQL link with this string as a key. The next time someone calls a pconnect() with the same host/user/passwd, the same key would be generated, and the function would find the SQL link in the persistent list.
Until further documented, you should look at mysql.c or msql.c to see how one should use the plist's hash table abilities.
One important thing to note: resources going into the persistent resource list must *NOT* be allocated with PHP's memory manager, i.e., they should NOT be created with emalloc(), estrdup(), etc. Rather, one should use the regular malloc(), strdup(), etc. The reason for this is simple - at the end of the request (end of the hit), every memory chunk that was allocated using PHP's memory manager is deleted. Since the persistent list isn't supposed to be erased at the end of a request, one mustn't use PHP's memory manager for allocating resources that go to it.
When you register a resource that's going to be in the persistent list, you should add destructors to it both in the non-persistent list and in the persistent list. The destructor in the non-persistent list destructor shouldn't do anything. The one in the persistent list destructor should properly free any resources obtained by that type (e.g. memory, SQL links, etc). Just like with the non-persistent resources, you *MUST* add destructors for every resource, even it requires no destructotion and the destructor would be empty. Remember, since emalloc() and friends aren't to be used in conjunction with the persistent list, you mustn't use efree() here either.

The steps required to add a new directive:
Add directive to php3_ini_structure struct in mod_php3.h.
In main.c, edit the php3_module_startup function and add the appropriate cfg_get_string() or cfg_get_long() call.
Add the directive, restrictions and a comment to the php3_commands structure in mod_php3.c. Note the restrictions part. RSRC_CONF are directives that can only be present in the actual Apache .conf files. Any OR_OPTIONS directives can be present anywhere, include normal .htaccess files.
In either php3take1handler() or php3flaghandler() add the appropriate entry for your directive.
In the configuration section of the _php3_info() function in functions/info.c you need to add your new directive.
And last, you of course have to use your new directive somewhere. It will be addressable as php3_ini.directive.
³»ºÎ ÇÔ¼ö(internal function)¿¡¼ »ç¿ëÀÚ ÇÔ¼ö¸¦ ºÎ¸£·Á¸é, call_user_function() ÇÔ¼ö¸¦ »ç¿ëÇÏ¿©¾ß ÇÑ´Ù.
call_user_function() returns SUCCESS on success, and FAILURE in case the function cannot be found. You should check that return value! If it returns SUCCESS, you are responsible for destroying the retval pval yourself (or return it as the return value of your function). If it returns FAILURE, the value of retval is undefined, and you mustn't touch it.
All internal functions that call user functions must be reentrant. Among other things, this means they must not use globals or static variables.
call_user_function() takes six arguments:
This is the hash table in which the function is to be looked up.
This is a pointer to an object on which the function is invoked. This should be NULL if a global function is called. If it's not NULL (i.e. it points to an object), the function_table argument is ignored, and instead taken from the object's hash. The object *may* be modified by the function that is invoked on it (that function will have access to it via $this). If for some reason you don't want that to happen, send a copy of the object instead.
The name of the function to call. Must be a pval of type IS_STRING with function_name.str.val and function_name.str.len set to the appropriate values. The function_name is modified by call_user_function() - it's converted to lowercase. If you need to preserve the case, send a copy of the function name instead.
A pointer to a pval structure, into which the return value of the invoked function is saved. The structure must be previously allocated - call_user_function() does NOT allocate it by itself.
The number of parameters being passed to the function.
An array of pointers to values that will be passed as arguments to the function, the first argument being in offset 0, the second in offset 1, etc. The array is an array of pointers to pval's; The pointers are sent as-is to the function, which means if the function modifies its arguments, the original values are changed (passing by reference). If you don't want that behavior, pass a copy instead.
