Get List of All Folders In Google Drive - Google Drive API

Question

Is there any way to get a list of all folders in "My Drive" using the Google Drive API. Here is the function I am trying to write.

function getAllFolders(){
    // Get all folders
}

(I looked at some other stack overflow posts but they weren't very helpful for me).

With the query string q , you can search for files and folders following the syntax in the documentation

Using mimeType = 'application/vnd.google-apps.folder' in the query string, to get just the folders.

there is a simple exemple:

<?php

$service = new Google_Service_Drive($client);
$folderID = "root";

$optParams = array(
            'pageSize' => 100,
            'fields' => 'nextPageToken, files(id, name, mimeType, modifiedTime, size, parents)',
            'q' => "mimeType = 'application/vnd.google-apps.folder' and '".$folderID."' in parents"
        );
        
$results = $service->files->listFiles($optParams);
foreach ($results as $file) {
    // do somethings
}
