本文实例为大家分享了php微信公众号二级菜单的具体代码，供大家参考，具体内容如下

核心代码：

 $time = time();
 $texttpl = "<xml>
    <tousername><![cdata[%s]]></tousername>
     <fromusername><![cdata[%s]]></fromusername>
     <createtime>%s</createtime>
      <msgtype><![cdata[text]]></msgtype>
      <content>%s</content>
     <funcflag>0</funcflag>
    </xml>";

     /*！！！注意，无法再通过本次连接调用mysql_select_db来切换到其它数据库了！！！*/
     /* 需要再连接其它数据库，请再使用mysql_connect+mysql_select_db启动另一个连接*/
