Note: copy map code work but the delete directory doesn't.

I use this code for delete directory:

PHP:

public function deleteDirectory($dirPath) {
    if (is_dir($dirPath)) {
        $objects = scandir($dirPath);
        foreach ($objects as $object) {
            if ($object != "." && $object != "..") {
                if (filetype($dirPath . DIRECTORY_SEPARATOR . $object) == "dir") {
                    $this->deleteDirectory($dirPath . DIRECTORY_SEPARATOR . $object);
                } else {
                    unlink($dirPath . DIRECTORY_SEPARATOR . $object); //This is 1162 line
                }
            }
        }
        reset($objects);
        rmdir($dirPath);
    }
}


How i can fix it please?
