glob
(PHP 4 >= 4.3.0, PHP 5)
glob — Find pathnames matching a pattern
Description
$pattern
[, int $flags = 0
] )
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.
Parameters
-
pattern -
The pattern. No tilde expansion or parameter substitution is done.
-
flags -
Valid flags:
-
GLOB_MARK- Adds a slash to each directory returned -
GLOB_NOSORT- Return files as they appear in the directory (no sorting) -
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GLOB_NOESCAPE- Backslashes do not quote metacharacters -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.
-
Return Values
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.
Changelog
| Version | Description |
|---|---|
| 5.1.0 |
GLOB_ERR was added
|
| 4.3.3 |
GLOB_ONLYDIR became available on Windows and
other systems not using the GNU C library
|
Examples
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
Notes
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).
Note: The
GLOB_BRACEflag is not available on some non GNU systems, like Solaris.
