thinkphp的$this的用法介绍（附代码）

本篇文章给大家带来的内容是关于thinkphp的$this的用法介绍（附代码），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。

常用方法：

$this -> user[''id] 在user表中查询user_info ，user_info的其它字段值可以去对应的主表中查询各种值。

在HomeController.class.php中建立几个方法（获取渠道消息，获取用户消息，获取推广信息等） 并在一开始就调用，在其它php中public function _initialize(){

parent::_initialize();} 引入这些常用的方法产生的array(用户、渠道、推广等)，$this -> user[''id] 在user表中查询user_info ，user_info的其它字段值可以去对应的主表中查询各种值。
