require_once 'autoload.php';
use Facebook\FacebookSession;

// init app with app id and secret
//FacebookSession::setDefaultApplication( 'Your APP ID','Your APP Secret' );
// login helper with redirect_uri
$helper = new FacebookRedirectLoginHelper('Your Redirect URL');

If the user registered before then our system will redirect the user to my account page otherwise it will ask the user to register for the first time.

/*Check if the user connected before */
$sql = db_query("select * from register_facebook where passcode='".$fbid."'");
$numrow = mysqli_num_rows($sql);
if($numrow > 0){
	$_SESSION['email'] 		= $femail;
	$_SESSION['passcode'] 	= $fbid;
	$_SESSION['FBID'] = $fbid;           
	$_SESSION['USERNAME'] = $fbuname;
	$_SESSION['FULLNAME'] = $fbfullname;
	$_SESSION['EMAIL'] =  $femail;
