I am writing here the PHP code for deleting the directory.
<?php $extract_dir = 'path'; //physical path of the directory if(deleteDirectory($extract_dir)) //delete directory { $msg = "$extract_dir was deleted"; echo $msg."<br/>"; } else { $msg = "$extract_dir was not deleted"; echo $msg."<br/>"; } //delete directory and files inside it //start function deleteDirectory($dir) { if (!file_exists($dir)) return true; if (!is_dir($dir)) return unlink($dir); foreach (scandir($dir) as $item) { if ($item == '.' || $item == '..') continue; if (!deleteDirectory($dir.DS.$item)) return false; } return rmdir($dir); } //end ?>
