    The Private Function checksignature () {$signature = $_get["signature"];
    $timestamp = $_get["timestamp"];
    $nonce = $_get["nonce"];
    $token = token;
    $TMPARR = Array ($token, $timestamp, $nonce);
    Sort ($TMPARR, sort_string);
    $TMPSTR = implode ($TMPARR);
    $TMPSTR = SHA1 ($TMPSTR);
    if ($tmpStr = = $signature) {return true;
    }else{return false;
    The Public Function responsemsg () {$postStr = $GLOBALS ["Http_raw_post_data"]; if (!empty ($POSTSTR)) {$POSTOBJ = simplexml_load_string ($postStr, ' simplexmlelement ', LIBXml_nocdata);
