往SESSION写东西:

<?php
 class IndexAction extends Action {
         function index(){
                 $this->display();
         }

        function do_login(){
                //获取用户名和密码信息,和数据库中比对
                 $_SESSION["aaa"]="ssada1";
                 echo 111111111;
                 dump($_POST);
                 echo 222222222;
                 dump($_SESSION);
                 echo 33333333;
