session_unset and session_destroy

dico

Hi,

I just want to double check the usage of both session_unset and session_destroy.

I have a web page with 2 cookies being set. I want to delete all traces of one of the cookies after the person clicks on a link. The other cookie should remain the same.

Do I do this by:

session_unset('cookie_name');
session_destroy('cookie_name');

Thanks,

Installer

Use setcookie() to delete a cookie.

Cookies must be deleted with the same parameters as they were set with. If the value argument is an empty string (""), and all other arguments match a previous call to setcookie, then the cookie with the specified name will be deleted from the remote client.

When deleting a cookie you should assure that the expiration date is in the past, to trigger the removal mechanism in your browser.
