Yii cookie与session使用

//设置cookie
$ck=new CHttpCookie('hobby','篮球');
$ck->expire=time()+3600;
//把$ck对象放入cookie组件里边
Yii::app()->request->cookies['hobby']=$ck;
$ck2=new CHttpCookie('sex', '男');
$ck2->expire=time()+3600;
//把$ck对象放入cookie组件里面
Yii::app()->request->cookies['sex']=$ck2;
//访问cookie
echo Yii::app()->request->cookies['hobby'];
echo Yii::app()->request->cookies['sex'];
//删除cookie
unset(Yii::app()->request->cookies['sex']);

//设置session,通过session组件来设置
Yii::app()->session['username']="yaojun";
Yii::app()->session['useradd']="beijing";
//使用session
echo Yii::app()->session['username'];
echo Yii::app()->session['useradd'];
//删除一个session
unset(Yii::app()->session['useradd']);
//删除全部session
Yii::app()->session->clear();//删除session变量
Yii::app()->session->destroy();//删除服务器的session信息
