if( $tmpstr == $signature ){

3.调用回复信息方法
在wx_sample.php文件中注释掉$wechatobj->valid();，在其下增加一句“$wechatobj->responsemsg();”。

4.关键词自动回复和关注回复
$keyword保存着用户微信端发来的文本信息。
官方开发者文档：https://mp.weixin.qq.com/wiki/home/index.html（消息管理-》接收消息-接收事件推送-》1.关注/取消关注事件）

关注事件与一般的文本消息有两处不同，一是msgtype值是event，二是增加了event值是subscribe。由于官方文档（最初的wx_sample.php）没有提取这个参数，需要我们自己提取。在程序中增加两个变量$msgtype和$event。
