ajax cookie nbsp setcookie uid

setcookie的问题
setcookie('uid', $id);

1.如果第三参数不传,是不是就是退出浏览器cookie就失效?

2.我用jquery的$ajax调用php,php里执行了setcookie('uid', $id, $cookietime, '/', '.xxx.net', 0);
在$ajax success里reload了页面,为什么取不到cookie?
而且在%temp%\..\Temporary Internet Files目录下也看不到对应网站的cookie文件。


------解决方案--------------------
setcookie('uid',null)
------解决方案--------------------
统一一下,不用这个setcookie('uid');
setcookie("uid", "", time() - 3600);比较标准
------解决方案--------------------
