Return Values
Returns a directory handle resource on success, or
FALSE on failure.
If path is not a valid directory or the
directory can not be opened due to permission restrictions or
filesystem errors, opendir() returns FALSE and
generates a PHP error of level
E_WARNING. You can suppress the error output of
opendir() by prepending
'@' to the
front of the function name.

Examples
Example 1. opendir() example
<?php $dir = "/etc/php5/";
// Open a known directory, and proceed to read its contents if (is_dir($dir)) { if ($dh = opendir($dir)) { while (($file = readdir($dh)) !== false) { echo "filename: $file : filetype: " . filetype($dir . $file) . "\n"; } closedir($dh); } } ?>

something similar to:
filename: . : filetype: dir
filename: .. : filetype: dir
filename: apache : filetype: dir
filename: cgi : filetype: dir
filename: cli : filetype: dir
