Simple automatic reply

We made some modifications in the official example to implement a message "?" You can reply to the current time function.
In this example, a text message ($ postObj-> Content) is received and a text message ($ msgType = "text";) is returned.
You can save the following code as index. php and re-upload it as shown above.
The code is as follows:

 define("TOKEN", "pondbay");$wechatObj = new wechatCallbackapiTest();$wechatObj->responseMsg();class wechatCallbackapiTest{    public function responseMsg()    {        $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];        if (!empty($postStr)){            $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);            $fromUsername = $postObj->FromUserName;            $toUsername = $postObj->ToUserName;            $keyword = trim($postObj->Content);            $time = time();            $textTpl = "
