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