glob — Find pathnames matching a pattern
glob ( string $pattern [, int $flags = 0 ] ) : array
The glob() function searches for all the pathnames matching pattern
according to the rules used by the libc glob() function, which is similar to the rules used by common shells.
pattern
The pattern. No tilde expansion or parameter substitution is done.
Special characters:
*
- Matches zero or more characters. ?
- Matches exactly one character (any character). [...]
- Matches one character from a group of characters. If the first character is !
, matches any character not in the group. \
- Escapes the following character, except when the GLOB_NOESCAPE
flag is used. flags
Valid flags:
GLOB_MARK
- Adds a slash (a backslash on Windows) to each directory returned GLOB_NOSORT
- Return files as they appear in the directory (no sorting). When this flag is not used, the pathnames are sorted alphabetically GLOB_NOCHECK
- Return the search pattern if no files matching it were found GLOB_NOESCAPE
- Backslashes do not quote metacharacters GLOB_BRACE
- Expands {a,b,c} to match 'a', 'b', or 'c' GLOB_ONLYDIR
- Return only directory entries which match the pattern GLOB_ERR
- Stop on read errors (like unreadable directories), by default errors are ignored. Note: The
GLOB_BRACE
flag is not available on some non GNU systems, like Solaris.
Returns an array containing the matched files/directories, an empty array if no file matched or false
on error.
Note:
On some systems it is impossible to distinguish between empty match and an error.
Example #1 Convenient way how glob() can replace opendir() and friends.
<?php foreach (glob("*.txt") as $filename) { echo "$filename size " . filesize($filename) . "\n"; } ?>
The above example will output something similar to:
funclist.txt size 44686 funcsummary.txt size 267625 quickref.txt size 137820
Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
Note: This function isn't available on some systems (e.g. old Sun OS).
