Google Drive API PHP (create folder) - php

Question

I have problem with creating folder on my google drive by using Google Drive API.
The script successfully display me all files i have on my google drive from this part of code.
// Print the names and IDs for up to 10 files.
$optParams = array(
'pageSize' => 10,
'fields' => 'nextPageToken, files(id, name)'
);
$results = $service->files->listFiles($optParams);
if (count($results->getFiles()) == 0) {
print "No files found.<br>";
} else {
print "Files:<br>";
foreach ($results->getFiles() as $file) {
printf("%s (%s)<br>", $file->getName(), $file->getId());
}
}
but doesn't create folder from this part of code
// Create Test folder
$fileMetadata = new Google_Service_Drive_DriveFile(array(
'name' => 'Test',
'mimeType' => 'application/vnd.google-apps.folder'));
$file = $service->files->create($fileMetadata, array(
'fields' => 'id'));
printf("<br>Folder ID: %s<br>", $file->id);
There is full code of my php script.
<?php
require __DIR__ . '/google-api-php-client/vendor/autoload.php';
function getClient()
{
$client = new Google_Client();
$client->setApplicationName('Test Google Drive API');
$client->setScopes(Google_Service_Drive::DRIVE_METADATA_READONLY);
$client->setAuthConfig('client_secret.json');
// Load previously authorized token from a file, if it exists.
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
$tokenPath = 'token.json';
if (file_exists($tokenPath)) {
$accessToken = json_decode(file_get_contents($tokenPath), true);
$client->setAccessToken($accessToken);
}
// If there is no previous token or it's expired.
if ($client->isAccessTokenExpired()) {
// Refresh the token if possible, else fetch a new one.
if ($client->getRefreshToken()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
} 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);
$client->setAccessToken($accessToken);
// Check to see if there was an error.
if (array_key_exists('error', $accessToken)) {
throw new Exception(join(', ', $accessToken));
}
}
// Save the token to a file.
if (!file_exists(dirname($tokenPath))) {
mkdir(dirname($tokenPath), 0700, true);
}
file_put_contents($tokenPath, json_encode($client->getAccessToken()));
}
return $client;
}
// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Drive($client);
// Print the names and IDs for up to 10 files.
$optParams = array(
'pageSize' => 10,
'fields' => 'nextPageToken, files(id, name)'
);
$results = $service->files->listFiles($optParams);
if (count($results->getFiles()) == 0) {
print "No files found.<br>";
} else {
print "Files:<br>";
foreach ($results->getFiles() as $file) {
printf("%s (%s)<br>", $file->getName(), $file->getId());
}
}
// Create Test folder
$fileMetadata = new Google_Service_Drive_DriveFile(array(
'name' => 'Test',
'mimeType' => 'application/vnd.google-apps.folder'));
$file = $service->files->create($fileMetadata, array(
'fields' => 'id'));
printf("<br>Folder ID: %s<br>", $file->id);
