1、GET/POST 1.1、获取GET/POST过来的数据 Yii::app()->request->getParam('id'); 1.2、判断数据提交方式 Yii::app()->request->isPostRequest 2、session/cookie 2.1、session常用操作 $_SESSION 等价于 Yii::app()->session; 2.1.1、写入session //启动session $session=new CHttpSession; $session->open(); Yii::app()->session['key'] = 'value' 2.1.2、读取session Yii::app()->session['key'] 2.1.3、获取session的ID Yii::app()->session->sessionID 2.1.4、销毁session //移去所有session变量 Yii::app()->session->clear(); //移去存储在服务器端的数据 Yii::app()->session->destroy(); 2.1.5、session高级用法 $session = Yii::app()->session; $session['key'] = 'value'; var_dump($session['key']); 2.2 cookie 2.2.1 设置cookie $cookie = new CHttpCookie(‘mycookie’,'this is my cookie’); $cookie->expire = time()+60*60*24*30; //有限期30天 Yii::app()->request->cookies['mycookie']=$cookie; 2.2.2 读取cookie $cookie = Yii::app()->request->getCookies(); echo $cookie['mycookie']->value; 2.2.3 销毁cookie $cookie = Yii::app()->request->getCookies(); unset($cookie[$name]);
