Why is an error reported in this initialization function? ?

<code><?php
namespace Home\Controller;
use Think\Controller;
class CommonController extends Controller{
   public function _initialize(){
      echo seesion('URL', CONTROLLER_NAME.'/'.ACTION_NAME);
   }
}
?></code>

Brother, you typed the word wrong, it’s session not seesion.

Looking at the namespace you used, functions should be encapsulated into classes.
The error session is not defined. I guess what you want to do is:

<code>   #如果在 Controller 中定义 session：
   echo $this -> seesion('URL', CONTROLLER_NAME.'/'.ACTION_NAME);</code>

<code>   #如果是调用 原生的 SESSION：
   $_SESSION['URL', CONTROLLER_NAME.'/'.ACTION_NAME];
   echo $_SESSION['URL'];</code>
