3.調(diào)用回復(fù)信息方法
在wx_sample.php文件中注釋掉$wechatobj->valid();，在其下增加一句“$wechatobj->responsemsg();”。

4.關(guān)鍵詞自動回復(fù)和關(guān)注回復(fù)
$keyword保存著用戶微信端發(fā)來的文本信息。
官方開發(fā)者文檔：https://mp.weixin.qq.com/wiki/home/index.html（消息管理-》接收消息-接收事件推送-》1.關(guān)注/取消關(guān)注事件）
關(guān)注事件與一般的文本消息有兩處不同，一是msgtype值是event，二是增加了event值是subscribe。由于官方文檔（最初的wx_sample.php）沒有提取這個參數(shù)，需要我們自己提取。在程序中增加兩個變量$msgtype和$event。
