can request url , see if 404s or not?

function googlevideoexist($id) {     // validate id need     $id = (int) $id;      $headers = get_headers('http://video.google.com/videoplay?docid=' . $id, true);      // get_headers() follows location: headers,     // , sent in sequential order     foreach(array_reverse($headers) $header => $value) {         if (strstr($value, '200')) {           return true;        }     }      return false; }

url above guide - adapt suit. also, can use curl if more comfortable that.
