YII 獲取系統級請求參數的經常使用方法

一、GET/POST

1.一、獲取GET/POST過來的數據

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

1.二、判斷數據提交方式

1	Yii::app()->request->isPostRequest

二、session/cookie

2.一、session經常使用操做

$_SESSION 等價於 Yii::app()->session;

2.1.一、寫入session

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

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

2.1.二、讀取session

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

2.1.三、獲取session的ID

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

2.1.四、銷燬session

1 2 3 4

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

2.1.五、session高級用法

1 2 3

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

2.2 cookie

2.2.1 設置cookie

1 2 3

$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;

2.2.3 銷燬cookie

1 2	$cookie = Yii::app()->request->getCookies(); unset( $cookie [ $name ]);
