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：

     0
    ";

     /*接着调用mysql_connect()连接服务器*/

     /*至此连接已完全建立，就可对当前数据库进行相应的操作了*/
     /*！！！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*/

      * 接下来就可以使用其它标准php mysql函数操作进行数据库操作
      */
