 1  private function _responseMsg() 
 2     {
 3         $post_str = file_get_contents('php://input');
 4         if (!empty($post_str)) {
 5             // 解析微信传过来的 XML 内容
 6             $post_obj      = (array)simplexml_load_string($post_str, 'SimpleXMLElement', LIBXML_NOCDATA);
 7             $from_username = $post_obj['FromUserName'];
 8             $to_username   = $post_obj['ToUserName'];
 9             $MsgType       = $post_obj['MsgType'];    //消息类型，event
10             $Event         = $post_obj['Event'];      //事件类型，subscribe(订阅)、unsubscribe(取消订阅)
11             $EventKey      = $post_obj['EventKey'];   //扫码关注时 带的信息

这里的 $post_obj['FromUserName'] 就是 当前用户的 openID
