Check if the token has a refresh-token (if you request offline access, the refresh-token will be sent with the access token the first time).

Something like this

 $token = $client->getAccessToken();
 $authObj = json_decode($token);
 if(isset($authObj->refresh_token)) {
     save_refresh_token($authObj->refresh_token);
 }

Where save_refresh_token saves your refresh-token somewhere (db).

Then you can check if token as expired by:

 $client->isAccessTokenExpired()

If it is, you can update it with:

$client->refreshToken($your_saved_refresh_token);

And then set your new access token to the session:

 $_SESSION['access_token'] = $client->getAccessToken();
