can I bulk delete subscribers from multiple groups at once using the Mailchimp API

1. Identify the Subscribers

1. Use the `lists/{list_id}/members` endpoint to get a list of all subscribers in the list.
2. Filter the list to include only the subscribers you want to delete.

2. Create a Batch Operation

1. Use the `lists/{list_id}/members/batch` endpoint to create a batch operation.
2. Specify the `action` as `delete` and the `ids` as the subscriber IDs you want to delete.

3. Execute the Batch Operation

1. Use the `lists/{list_id}/members/batch/{batch_id}` endpoint to execute the batch operation.
2. The batch operation will delete the specified subscribers from the list.

Example PHP Code

Here's an example of how you can use the Mailchimp API to bulk delete subscribers from multiple groups at once in PHP:

php
<?php
require_once 'path/to/mailchimp-api/vendor/autoload.php';

use \DrewM\MailChimp\MailChimp;

// Initialize the Mailchimp API client
$mailchimp = new MailChimp(MAILCHIMP_API_KEY);
$mailchimp->setConfig(['server' => 'YOUR_SERVER_PREFIX']);

// Get the list ID
$listId = '**********';

// Get the subscriber IDs
$subscriberIds = array_map('md5', array_filter(array_map('strtolower', array_map('trim', array_map('explode', ',', '
