$WECHATOBJ = new Wechatcallbackapitest ();
if (Isset ($_get[' echostr ')) {
  $wechatObj->valid ();
} else{
  $wechatObj->responsemsg ();
}

The Wechatcallbackapitest class has the following code:

Class Wechatcallbackapitest {public function valid () {$echoStr = $_get["Echostr"];
      if ($this->checksignature ()) {echo $echoStr;
    Exit
    The Private Function checksignature () {$signature = $_get["signature"];
    $timestamp = $_get["timestamp"];
    $nonce = $_get["nonce"];
    $token = token;
    $TMPARR = Array ($token, $timestamp, $nonce);
    Sort ($TMPARR);
    $TMPSTR = implode ($TMPARR);
    $TMPSTR = SHA1 ($TMPSTR);
    if ($tmpStr = = $signature) {return true;
    }else{return false;
    The Public Function responsemsg () {$postStr = $GLOBALS ["Http_raw_post_data"];
      if (!emptyempty ($POSTSTR)) {$POSTOBJ = simplexml_load_string ($postStr, ' simplexmlelement ', libxml_nocdata);
      $fromUsername = $POSTOBJ->fromusername;
      $toUsername = $POSTOBJ->tousername;
      $keyword = Trim ($postObj->content);
      $time = time (); $TEXTTPL = "<xml> <tousername><! [cdata[%s]]></ToUserName> <fromusername><! [cdata[%s]]></fromusername> <CreateTime>%s</CreateTime> <msgtype><![ Cdata[%s]]></msgtype> <content><!
      [cdata[%s]]></content> <FuncFlag>0</FuncFlag> </xml> "; if ($keyword!= "" | |!
  Emptyempty ($keyword)) {Msgtype = "text";
  $contentStr. = Date ("Y-m-d h:i:s", Time ());
  $RESULTSTR = sprintf ($TEXTTPL, $fromUsername, $toUsername, $time, $msgType, $CONTENTSTR);
