Was recently working on a project where needed to delete a folder and its sub-folders and files. Here is a snippet that can help you to remove a non-empty directory from the server. It’s a recursive function that deletes the directory with its files, folders and sub-folders.

< ?php
function do_clean($dir,$itself)
if ($handle = opendir($dir))
$array = array();

    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {

				if(!@rmdir($dir.$file)) // Empty directory? Remove it
                do_clean($dir.$file.'/',$itself); // Not empty? Delete the files inside it

	if($itself) @rmdir($dir); // allows to delete main directory


//and here how to call function:
do_clean(/home/path/to/mysite.com/folder_to_delete/);// IMPORTANT: with '/' at the end
