Using `header("Location: …)`

Question

I am using a location() function call in my configuration file, but it keeps redirecting me to the page I am making to go to in the call to it,

I am doing this:

if (!isset($_SESSION['user_login_name']) || !isset($_SESSION['user_logged_in']))
{
    header("Location: /login/");
    exit();
}

What is the best way to make it so the server knows that it on the login page and not redirect back to this infinitely?

I think that the best way to do this would be to have a $_SERVER check to see if the current script is in the /login/ directory, this could be as follows:

if (!isset($_SESSION['user_login_name']) || !isset($_SESSION['user_logged_in']))
{
    if ($_SERVER['SCRIPT_NAME'] !== '/login/index.php')
    {
        header("Location: /login/");
        exit();
    }
}
