How can PHP scripts be structured to ensure that the data remains current when included in JavaScript?

When including PHP data in JavaScript, it's important to ensure that the data remains current. One way to achieve this is by using AJAX to fetch the data dynamically from the server without the need to reload the page. By doing so, the JavaScript code can always access the most up-to-date information from the server. 

<?php
// PHP script to fetch data dynamically
$data = // fetch data from database or API

header('Content-Type: application/json');
echo json_encode($data);
?>
