1. config.php : In this file, we have to add facebook app id and secret.

2. index.php : In this file, we have to add layout file and manage if login then different layout and different for logout user.

3. storeData.php : In this file, i write database logic, We will insert and check user data from this file.

4. logout.php : In this file, we destroy session for logout user.



require 'api/facebook.php';

$config['App_ID'] = 'Facebook App Id';

$config['App_Secret'] = 'Facebook App Secret';

$facebook = new Facebook(array(

'appId' => $config['App_ID'],

'secret' => $config['App_Secret']





require 'config.php';

require 'storeData.php';

$user = $facebook->getUser();
