What are the potential challenges of implementing Google Login in PHP with the new API, especially in relation to accessing user information from SQL?

One potential challenge of implementing Google Login in PHP with the new API is securely accessing and storing user information from SQL. To address this, you can use OAuth 2.0 to authenticate users and retrieve their information from Google, then securely store the relevant data in your SQL database. 

// Include Google Client Library
require_once 'vendor/autoload.php';

// Set up Google Client
$client = new Google_Client();
$client->setAuthConfig('client_secret.json');
$client->addScope('email');
$client->addScope('profile');

// Authenticate user
if (isset($_GET['code'])) {
    $token = $client->fetchAccessTokenWithAuthCode($_GET['code']);
    $client->setAccessToken($token['access_token']);

    // Get user information
    $oauth = new Google_Service_Oauth2($client);
    $user = $oauth->userinfo->get();

    // Store user information in SQL
    $sql = "INSERT INTO users (google_id, name, email) VALUES ('".$user->id."', '".$user->name."', '".$user->email."')";
    // Execute SQL query
}
