yii对cookie的操作常见的主要有以下几种：

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.读取cookie:

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

3.销毁cookie:

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