$client = new Google_Client();
$client->setApplicationName("Google OAuth Login Example");
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);
$client->setDeveloperKey($simple_api_key);
$client->setAccessType('offline');
$client->setScopes(array('https://www.googleapis.com/auth/calendar',"https://www.googleapis.com/auth/userinfo.email"));


$objOAuthService = new Google_Service_Oauth2($client);

if ($client->getAccessToken()) {
    $userData = $objOAuthService->userinfo->get();
    $_SESSION['access_token'] = $client->getAccessToken();
 }
 print_r($userData);

userdata will have info about logged in user.
