The following script defines a function called buildUrl(), which is intended to be a crude way of normalizing URLs. What line of code must be inserted into buildUrl() to ensure $url1 and code $url2 are both equal to http://phpriot.com/quiz/?

                        function buildUrl($domain, $path) {
    // insert line of code here
    return $ret;
