yii 獲取系統級請求參數的常用方法

1、GET/POST

1.1、獲取GET/POST過來的數據

1	Yii::app()->request->getParam('id');

1.2、判斷數據提交方式

$_SESSION 等價於 Yii::app()->session;

2.1.1、寫入session

//啓動session
$session=new CHttpSession;
$session->open();

1	Yii::app()->session['key'] = 'value'

2.1.2、讀取session

1	Yii::app()->session['key']

2.1.3、獲取session的ID

1	Yii::app()->session->sessionID

2.1.4、銷燬session

//移去所有session變量 Yii::app()->session->clear(); //移去存儲在服務器端的數據 Yii::app()->session->destroy();

2.1.5、session高級用法

$session = Yii::app()->session; $session['key'] = 'value'; var_dump($session['key']);

2.2 cookie

2.2.1 設置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 讀取cookie

1 2	$cookie = Yii::app()->request->getCookies(); echo $cookie['mycookie']->value;
