Интеграция Google Analytics с Laravel

Я пытаюсь интегрировать API Google Analytics с Laravel. Я следую этому уроку HelloAnalytics.php но пока я сталкиваюсь с препятствием. Я достиг той части Code Summary: Authentication and Authorization и я столкнулся с множественными ошибками до сих пор.
Вот мой код:

class UserController extends BaseController {public function analytics()
{
session_start();

$client = new Google_Client();
$client = new apiClient(); //that's the one supposed to be there but I got Class 'apiClient' not found so I changed it to the one above
$client->setApplicationName('Hello Analytics API Sample');

// Visit https://console.developers.google.com/ to generate your
// client id, client secret, and to register your redirect uri.
$client->setClientId('id');
$client->setClientSecret('secret');
$client->setRedirectUri('redirect_uri');
$client->setDeveloperKey('apikey');
$client->setScopes(array('https://www.googleapis.com/auth/analytics.readonly'));

// Magic. Returns objects from the Analytics Service instead of associative arrays.
$client->setUseObjects(true); //This line also causes an error stating Call to undefined method Google_Client::setUseObjects()

if (isset($_GET['code'])) {
$client->authenticate();
$_SESSION['token'] = $client->getAccessToken();
$redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}

if (isset($_SESSION['token'])) {
$client->setAccessToken($_SESSION['token']);
}

if (!$client->getAccessToken()) {
$authUrl = $client->createAuthUrl();
print "<a class='login' href='$authUrl'>Connect Me!</a>";

} else {
$analytics = new Google_AnalyticsService($client);//Also another error here: Class 'Google_AnalyticsService' not found
runMainDemo($analytics);
}

}
}

В моем файле php.in я добавил следующее:

include_path=".:/usr/local/share/pear:/usr/local/PEAR:C:\xampp\htdocs\google-api-php-client\src"

Любая помощь могла бы быть полезна.
