Facebook and oauth 2.0 cookie changes

This function was used for me until the day when facebook decided to force some changes.

    function get_facebook_cookie() {
    $app_id             = '[MyAppID]';
    $application_secret = '[MyAppSecrect]';

    if(isset($_COOKIE['fbs_' . $app_id])){
        $args = array();
        parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
        ksort($args);
        $payload = '';
        foreach ($args as $key => $value) {
                if ($key != 'sig') {
                $payload .= $key . '=' . $value;
                }
        }
        if (md5($payload . $application_secret) != $args['sig']) {
                return null;
        }
        return $args;
        } else {
         return null;
        }
}

I was able to access the FB user token as easily as

$cookie['access_token']

Now it seems to me that I can no longer get this information.

I was successfully (easily) able to make the necessary changes to my javascript code, but I'm kind of fixated on the php side. As a quick note, I use codeigniter, and I had a lot of problems trying to get the FB PHP SDK to play well, I also have not seen examples of integrating PHP 3 SDK into codeigniter, so I'm looking for a quick and dirty solution that will allow me to get the access token from cookie, which allows me to use the following Facebook API call:

'https://api.facebook.com/method/friends.getAppUsers?access_token=' . $cookie['access_token'];

Any help is greatly appreciated.
