how do i get facebook user login status?

Question

I am using yii framework and want to know the login status of facebook user. I am using $_REQUEST["code"] to get the user login status, but am facing some problem. I want to know if I can check session for it or get logged in status some other way..??

Answer 1

I used php sdk and below are the codes:

 $facebook = new Facebook(…);
 $session = $facebook->getSession();
 if ($session) {
 // proceed knowing you have a valid user session
 } else {
  // proceed knowing you require user login and/or authentication
 }
