Basically, you use the PHP SDK to get the login URL and then do a JavaScript redirect to that URL. The example http://github.com/facebook/php-sdk/blob/master/examples/example.php does everything for you except for the redirect. In the example, they have a link you click to login. If you want it to be automatic, do the following.

<script>
    FB.getLoginStatus(function(response) {
        if (response.session) {
            // Logged in and connected user, someone you know.
        } 
        else {
            // No user session available, redirect them to login.
            window.top.location = <?php echo $loginUrl; ?>
        }
    });
</script>
