undefined index client_id

[PHP-HIMANK]

I got an error - unknown index client_id. In client.php I set client_id and secret_id but still it did not work.

<?php 
require __DIR__ . '/vendor/autoload.php';
if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}
/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Gmail API PHP Quickstart');
    $client->setScopes(Google_Service_Gmail::GMAIL_READONLY);
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    // Load previously authorized credentials from a file.
    $credentialsPath = 'token.json';
    if (file_exists($credentialsPath)) {
        $accessToken = json_decode(file_get_contents($credentialsPath), true);
    } else {
        // Request authorization from the user.
        $authUrl = $client->createAuthUrl();
        printf("Open the following link in your browser:\n%s\n", $authUrl);
        print 'Enter verification code: ';
        $authCode = trim(fgets(STDIN));
        // Exchange authorization code for an access token.
        $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
        // Store the credentials to disk.
        if (!file_exists(dirname($credentialsPath))) {
            mkdir(dirname($credentialsPath), 0700, true);
        }
        file_put_contents($credentialsPath, json_encode($accessToken));
        printf("Credentials saved to %s\n", $credentialsPath);
    }
    $client->setAccessToken($accessToken);
    // Refresh the token if it's expired.
    if ($client->isAccessTokenExpired()) {
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
    }
    return $client;
}
// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Gmail($client);
// Print the labels in the user's account.
$user = 'me';
$results = $service->users_labels->listUsersLabels($user);
if (count($results->getLabels()) == 0) {
  print "No labels found.\n";
} else {
  print "Labels:\n";
  foreach ($results->getLabels() as $label) {
    printf("- %s\n", $label->getName());
  }

Can you post the contents of your credentials.json file, but with the actual secrets removed?
