Demo OAuth Login for Facebook Twitter and Google Plus Using PHP

Demo OAuth Login for Facebook Twitter and Google Plus Using PHP

I had kept this social login handling in a separate php file (login.php), where i included all php SDK of Facebook, Twitter and login. When user clicks on login with Facebook, Twitter or Google, then user will be redirected to this login.php file. This login.php will make login request to Facebook, Twitter or Google. Once user successfully authenticated, then OAuth response will be saved in database and let the user to login in our application.



Here is the login.php file script.

require_once 'config.php';

//initalize user class
$user_obj = new Cl_User();

    if ($response instanceof stdClass && isset($response->access_token)) {

    return new FacebookSession($response->access_token);


    if (is_array($response) && isset($response[‘access_token’])) {

    return new FacebookSession($response[‘access_token’]);
