Yii框架Session与Cookie使用方法示例_php实例_

 public function actionIndex(){ $session = \YII::$app->session; //判断session是否开启 if(!$session->isActive) { //未开启,需要开启 $session->open(); } //设置session $session->set('user_name','zhangsan'); //获取session $user_name = $session->get('user_name'); echo $user_name; //删除session $session->remove('user_name'); //数组形式的session //设置session $session['userName'] = 'lisi'; //获取session $user_name = $session['userName']; echo $user_name; //删除session unset($session['userName']); } 

 public function actionIndex(){ //设置cookie(注意这里用的是响应组件) $cookies = \YII::$app->response->cookies; $cookie_data = array('name'=>'user','value'=>'zhangsan'); $cookies->add(new Cookie($cookie_data)); //获取cookie(注意这里用的是请求组件) $cookie = \YII::$app->request->cookies; echo $cookie->getValue('user','default_value');//第二个参数为不存在时的默认值 //删除cookie(注意这里用的是响应组件) $cookies->remove('user'); }
