        $objects = scandir($directory);
        foreach ($objects as $object) {
            if ($object != "." && $object != "..") {
                if (is_dir($directory . DIRECTORY_SEPARATOR . $object) && !is_link($directory . DIRECTORY_SEPARATOR . $object)) {
                    recursiveDelete($directory . DIRECTORY_SEPARATOR . $object);
                } else {
                    unlink($directory . DIRECTORY_SEPARATOR . $object);
                }
            }
