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。
