Here' is a function to remove the last n part of a URL:

/**
 * remove the last `$level` of directories from a path
 * example 'aaa/bbb/ccc' remove 2 levels will return aaa/
 *
 * @param $path
 * @param $level
 *
 * @return mixed
 */
public function removeLastDir($path, $level)
{
    if (is_int($level) && $level > 0) {
        $path = preg_replace('#\/[^/]*$#', '', $path);

        return $this->removeLastDir($path, (int)$level - 1);
    }

    return $path;
}
