PHP-General - How to set and unset cookie for a site with url rewrite?

Well on my site the url rewrite has been working like a charm, but right now I am encountering a big problem. I am unable to log out after logging in, which never happened before with the old system. The url for login and logout looks like these:



So yeah, both of them are in the same script file/controller. Login is the default/index action, while logout is a secondary operation.

The problem is that when I unset cookies with setcookie("cookie", "", time() - 3600), it only unset cookies for the pseudo-directory /login, but not for the entire domain and scriptpath. For this reason I appear to be logged out while visiting the login/logout page, but at anywhere else I am still logged in. There's nothing I can do about it...

So anyone of you familiar with url rewrite? Can you please help me fix this weird issue? And if I may ask, what do you do with your own login/logout system under url rewrite?

So why can't you set the path in the call to setcookie()?

Thanks for the reply, and well actually I sorta fixed the problem by inserting $_SERVER['HTTP_HOST']. The only remaining issue is that it may end up clearing cookies for all subdomains, so I wonder if there's a way to specify one particular subdomain.

Yes, there is. Specify the domain. I'm not sure what the question even is. There's a variable for host. Use that.
