Update Seeds & Peer Help in Torrent Website

This is the code i'm using for updating stats for my website. http://piratex.us/What this script is doing is just updating stats of http Trackers. But i want a script that can update udp trackers as well. If Any one can help that will be great..

if ($scrape =='1'){
            print("<td valign='top' align='right'><br />");
            $seeders1 = $leechers1 = $downloaded1 = null;

            $tres = SQL_Query_exec("SELECT url FROM announce WHERE torrent=$id");
            while ($trow = mysql_fetch_assoc($tres)) {
                $ann = $trow["url"];
                $tracker = explode("/", $ann);
                $path = array_pop($tracker);
                $oldpath = $path;
                $path = preg_replace("/^announce/", "scrape", $path);
                $tracker = implode("/", $tracker)."/".$path;

                if ($oldpath == $path) {
                    continue; // Scrape not supported, ignored
                }

                // TPB's tracker is dead. Use openbittorrent instead
                if (preg_match("/thepiratebay.org/i", $tracker) || preg_match("/prq.to/", $tracker)) {
                    $tracker = "http://tracker.openbittorrent.com/scrape";
                }

                $stats = torrent_scrape_url($tracker, $row["info_hash"]);
                if ($stats['seeds'] != -1) {
                    $seeders1 += $stats['seeds'];
                    $leechers1 += $stats['peers'];
                    $downloaded1 += $stats['downloaded'];
                    SQL_Query_exec("UPDATE `announce` SET `online` = 'yes', `seeders` = $stats[seeds], `leechers` = $stats[peers], `times_completed` = $stats[downloaded] WHERE `url` = ".sqlesc($ann)." AND `torrent` = $id");
                } else {
                    SQL_Query_exec("UPDATE `announce` SET `online` = 'no' WHERE `url` = ".sqlesc($ann)." AND `torrent` = $id");

                }
            }

            if ($seeders1 !== null){ //only update stats if data is received
                print ("<b>".T_("LIVE_STATS").": </b><br />");
                print ("Seeders: ".number_format($seeders1)."<br />");
                print ("Leechers: ".number_format($leechers1)."<br />");
                print (T_("COMPLETED").": ".number_format($downloaded1)."<br />");

                SQL_Query_exec("UPDATE torrents SET leechers='".$leechers1."', seeders='".$seeders1."', times_completed='".$downloaded1."',last_action= '".get_date_time()."',visible='yes' WHERE id='".$row['id']."'");
            }else{
                print ("<b>".T_("LIVE_STATS").": </b><br />");
                print ("<font color='#ff0000'>Tracker Timeout<br />Please retry later</font><br />");
            }

            print ("<form action='torrents-details.php?id=$id&amp;scrape=1' method='post'><input type=\"submit\" name=\"submit\" value=\"Update Stats\" /></form></td>");
        }else{
