Is empty directory?

[pmdesign]

Hi,I just wanna know if there's any standart PHP function for checking directories if they are empty or not. If anyone has an idea how to do this let me know. I just wrote a function looping a dir and collectiong info about the number of files there. If it's 0 the dir is empty.<?php $number_of_files = 0;if ($handle = opendir('.')) { while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { $number_of_files++; } } closedir($handle); } ?>
