glob

(PHP 4 >= 4.3.0, PHP 5)

glob -- Find pathnames matching a pattern

Description

array glob ( string pattern [, int flags] )

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. No tilde expansion or parameter substitution is done.

Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.

Valid flags:

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 servers filesystem.

Note: This function isn't available on some systems (e.g. old Sun OS).

See also opendir(), readdir(), closedir(), and fnmatch().
