Yii框架学习笔记之session与cookie简单操作示例

本文实例讲述了Yii框架学习笔记之session与cookie操作。分享给大家供大家参考，具体如下：

session操作

<?php
  namespace app\controllers;
  use yii\web\Controller;
  class HelloController extends Controller{
public function actionIndex(){
     //把session当做对象
     $session = \yii:$app->session;
    if($session->isActive){
       echo "session isactive";
    }else{
       $session->open();
    }
    $session->set("user","张三");
    $session->get("user");
    $session->remove("user");
     //把session当做数组  
     $session['user'] = "张三";
     unset($session["user"]);
}
  }
?>

cookie操作

<?php
  namespace app\controllers;
  use yii\web\Controller;
  use yii\web\Cookie;
  class HelloController extends Controller{
    //存入cookie和修改cookie
    $cookies = \YII::$app->response->cookies;    
    $cookie_data = array('name'=>"user","value"=>"zhangsan");
    $cookies->add(new Cookie($cookie_data));//以'cookieValidationKey' 为基础的加密字符串
    $cookies->remove("id");//移除掉ID的cookie
    //取出cookie的值
    $cookies = \YII::$app->request->cookies;
    $cookies->getValue("user");
    //如果cookie不存在
    $cookies->getValue("user",20);//返回20
  }
?>

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
