	$file = array();
        $subdirectory = array();

        while(false !==($entry = $dh->read())) {
	     if($entry != "." && $entry != "..") {
                 if(is_dir($dir.'/'. $entry)) {
                      $subdirectory  = dirTree($dir.'/'.$entry); // subdirectory
                      if(is_array($subdirectory)) {
			$file = array_merge($file,$subdirectory);
                      }
                 }
                 else {
                      array_push($file, $dir. '/'. $entry);
                 }
             }
        }
        $dh->close();
        return $file;
    }


    print_r(dirTree('mydir'));
?>

Output
