cookie 问题 [ 新手入门 ]

$cookie = new CHttpCookie('Ud',$_GET['Ud']);
$cookie->expire = time()+60*60*24*30;  //有限期30天
$cookie->path = $this->TisWebsiteUrl;  //有限期30天
$cookie = new CHttpCookie('Pd',$_GET['Pd']);
$cookie->expire = time()+60*60*24*30;  //有限期30天
$cookie->path = $this->TisWebsiteUrl;  //有限期30天
$cookie = new CHttpCookie('Sid',$_GET['Sid']);
$cookie->expire = time()+60*60*24*30;  //有限期30天
$cookie->path = $this->TisWebsiteUrl;  //有限期30天
$cookie = new CHttpCookie('Ukey',$_GET['Ukey']);
$cookie->expire = time()+60*60*24*30;  //有限期30天
$cookie->path = $this->TisWebsiteUrl;  //有限期30天
Yii::app()->request->cookies['mycookie']=$cookie;

这样写也不对

报什么错误？
参考一下这个：
http://www.yiiframework.com/doc/api/1.1/CHttpCookie
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']=$cookie;
读取cookie:$cookie = Yii::app()->request->getCookies();

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

unset($cookie[$name]);

晕，兄弟看清楚问题，现在是要多个name,

第二楼的内容，只可以写入最后一个，别的写入不了

不要都用$cookie这一个变量名，多弄几个，好操作前两个。

点一下“回复”，这样我才能在“提醒”里看到回复。

$cookieUd = new CHttpCookie('Ud',$_GET['Ud'],'Pd'.$_GET['Pd'],'Sid'.$_GET['Sid'],'Ukey'.$_GET['Ukey']);
$cookieUd->expire = time()+60*60*24*30;  //有限期30天
$cookieUd->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
Yii::app()->request->cookies['Ud']=$cookieUd;

这样，

$cookiePd = new CHttpCookie('Pd'.$_GET['Pd']);
$cookiePd->expire = time()+60*60*24*30;  //有限期30天
$cookiePd->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
 Yii::app()->request->cookies['Pd']=$cookiePd;
	    
	    
$cookieSid = new CHttpCookie('Sid'.$_GET['Sid']);
$cookieSid->expire = time()+60*60*24*30;  //有限期30天
$cookieSid->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
Yii::app()->request->cookies['Sid']=$cookieSid;
	    
$cookieUkey = new CHttpCookie('Ukey'.$_GET['Ukey']);
$cookieUkey->expire = time()+60*60*24*30;  //有限期30天
$cookieUkey->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
Yii::app()->request->cookies['Ukey']=$cookieUkey;

下边这样，全不行，有没有好的方法，可以传多个

哪儿不行呢？报什么错误呢？

$cookieUd = new CHttpCookie('Ud',$_GET['Ud']);
$cookieUd->expire = time()+60*60*24*30;  //有限期30天
$cookieUd->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
Yii::app()->request->cookies['Ud']=$cookieUd;


$cookiePd = new CHttpCookie('Pd',$_GET['Pd']);
$cookiePd->expire = time()+60*60*24*30;  //有限期30天
$cookiePd->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
Yii::app()->request->cookies['Pd']=$cookiePd;


$cookieSid = new CHttpCookie('Sid',$_GET['Sid']);
$cookieSid->expire = time()+60*60*24*30;  //有限期30天
$cookieSid->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
Yii::app()->request->cookies['Sid']=$cookieSid;

$cookieUkey = new CHttpCookie('Ukey',$_GET['Ukey']);
$cookieUkey->expire = time()+60*60*24*30;  //有限期30天
$cookieUkey->path = $this->TisWebsiteUrl;  //有限期30天
// print_r($cookie);exit;
Yii::app()->request->cookies['Ukey']=$cookieUkey;

这样可以了，谢谢

这是哪儿错了呢？？？
