Answer 1

You have to delete cookies with php in your server and also with js for your browser.. (They has made with php, but cookie files are in the browser client too):

An example:

if ($_GET['action'] == 'exit'){
            // delete cookies with js and then in server with php:
            echo '
            
            ';
unset($_COOKIE['cookie_name']);
unset($_COOKIE['cookie_time']);
