What are some alternative methods to handle user interactions based on JavaScript activation?

When handling user interactions based on JavaScript activation, it's important to consider alternative methods for users who may have JavaScript disabled or unavailable. One approach is to use PHP to handle the interaction on the server-side, allowing for a fallback method that doesn't rely on JavaScript. 

<?php
if(isset($_POST['submit'])){
    // Handle user interaction here
    // This code will run even if JavaScript is disabled
}
?>
