Okay, I'm a bit new to php, sorry. I have a link called logout, code
being logout what would I need to do to call the
session_destroy() function from there? By the way, yes I am using
sessions for my authentication.<!-- ~MESSAGE_AFTER~ -->

just my opinion, have your logout link simply go to a new page with the
php needed, and a thank you in the html portion.<!-- ~MESSAGE_AFTER~ -->

Most likely you also have a cookie (?), and then you may want to destroy the cookie on logout. So you can read about that elsewhere, but essentially you set the expiration date to sometime in the past to make that happen.

Agreed, that way you can not only destroy the session but you can (as
another poster pointed out) destroy any cookies you may have and also unset
any global variables you may be using.

If you need any examples have a search around <a style='text-decoration: underline;' href="http://www.phpbuilder.com" target="_blank">www.phpbuilder.com</a> code
library section or (possibly better for tutorials) <a style='text-decoration: underline;' href="http://www.devshed.com/c/b/PHP#/" target="_blank">www.devshed.com/c/b/PHP#/</a>

Enjoy php - it is a fun language, post back if you need more help.

I use the same page for logging in and out, the URL passed is basically href="login.php?logout=true">logout

and on the page something like;

if(isset($logout)){
session_destroy();
echo Thanks, it was great;
blah blah blah
}

Another reason to have a seperate page is so you can put a logout link on
every page there is. The page does its thing, then automatically
redirects to another non-secure page.

But yea, always more than one way to skin a cat... if that term isnt too
