iterate through a folder (and any subfolders) and remove any folders that have no files in them (and no subdirectories).

Hi, I want to be able to iterate through a folder (and any subfolders) and remove any folders that have no files in them (and no subdirectories).

Ideally before deleting I want to run initially and for the output to just list the number of files (or 0) in each folder

Thanks

The easy way is for PHP to call find to do this...

find . -type d -empty -delete

Open in new window

Or you can rewrite all find's logic (shudder)...

Best to use existing + working tools, when they exist.

Thanks but I'm assuming that needs some kind of shell / command line access?

I got this to work though:

<?php

if ($handle = opendir('files')) {

	while (false !== ($entry = readdir($handle))) {

		if ($entry != "." && $entry != "..") {
		
			if (is_dir("files/".$entry)) {
			
				$_count = count(glob("files/".$entry."/*"));

				if ($_count == 0) {
					 unlink("files/".$entry);
				}

			} 
		}
	}
	
	closedir($handle);
	
}

?>
