How can a developer ensure that a web application functions properly even if JavaScript is disabled?

When JavaScript is disabled, a developer can ensure that a web application functions properly by implementing server-side processing using PHP. This means that critical functionality should be handled on the server rather than relying solely on client-side JavaScript. By using PHP to validate form submissions, handle data processing, and generate dynamic content, the web application can still operate smoothly even if JavaScript is disabled. 

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Handle form submission and data processing here
}
?>
