Are there any specific PHP libraries or tools that can simplify the process of downloading files via AJAX requests?

When downloading files via AJAX requests in PHP, it can be helpful to use a library like Guzzle to simplify the process. Guzzle is a popular HTTP client library that provides an easy way to make HTTP requests and handle responses. By using Guzzle, you can easily download files in PHP without having to worry about handling the low-level details of the HTTP protocol.

// Include Guzzle library
require 'vendor/autoload.php';

// Initialize Guzzle client
$client = new \GuzzleHttp\Client();

// Make a GET request to download a file
$response = $client->request('GET', 'http://example.com/file-to-download.zip');

// Save the downloaded file
file_put_contents('downloaded-file.zip', $response->getBody());
