Are there best practices for handling AJAX requests in PHP to prevent caching issues?

When making AJAX requests in PHP, caching can be an issue as the browser may cache the response and not fetch new data. To prevent caching, you can add headers to the PHP script that disable caching for the AJAX request. This can be done by setting the "Cache-Control" and "Pragma" headers to prevent caching. 

<?php
header("Cache-Control: no-cache, no-store, must-revalidate");
header("Pragma: no-cache");
header("Expires: 0");

// Your PHP code for handling the AJAX request goes here
?>
