<a href="<?=$loginUrl?>">

To get the user you need to use getUser which is missing in your code. It should be as

$facebook = new Facebook(array(
  'appId'     => $app_id,
  'secret'    => $app_secret,
  'cookie' => TRUE
  ));

$user = $facebook->getUser();

if($user){
  // Get logout URL
  $logoutUrl = $facebook->getLogoutUrl();
}else{
  // Get login URL
  $loginUrl = $facebook->getLoginUrl(array(
      'scope'         => 'read_stream, publish_stream, user_birthday, user_location, user_work_history, user_hometown, user_photos',
      'redirect_uri'  => $site_url,
      ));
}

getAccessToken() will give you the current access token being used by the SDK.
