Answer 1

You can simply use this customize function:

function unset_cookie($cookie_name) {
    if (isset($_COOKIE[$cookie_name])) {
        unset($_COOKIE[$cookie_name]);
        setcookie($cookie_name, null, -1);
    } else { return false; }
}

If you want to remove $_COOKIE['user_account'].
Just use:

unset_cookie('user_account');
