$client = new Google_Client(); $client->setClientSecret('your_client_secret'); $client->setRefreshToken('your_refresh_token'); if ($client->isAccessTokenExpired()) { $client->fetchAccessTokenWithRefreshToken(); } $accessToken = $client->getAccessToken();
$client = new Google_Client(); $client->setClientSecret('your_client_secret'); $client->setRefreshToken('your_refresh_token'); while (true) { if ($client->isAccessTokenExpired()) { $client->fetchAccessTokenWithRefreshToken(); } $accessToken = $client->getAccessToken(); // perform API requests with the access token // sleep for a certain amount of time before next iteration sleep(10); }In this example, the refreshToken method is used in a loop to continuously update the access token. The loop waits for the token to expire and then calls refreshToken to obtain a new token. The access token is then used to make API requests, and the loop sleeps for a certain amount of time before continuing to the next iteration. Package Library: Google API PHP client library
