How can PHP and JavaScript be effectively used together to filter and display data in real-time during form input?

To filter and display data in real-time during form input using PHP and JavaScript, you can utilize AJAX to send the form data to a PHP script for processing and then update the display based on the response. By combining the server-side processing power of PHP with the dynamic client-side capabilities of JavaScript, you can create a seamless user experience with real-time feedback. 

<?php
// filter_data.php

// Retrieve the form input data
$input_data = $_POST['input_data'];

// Perform filtering logic here
$filtered_data = filter_input($input_data);

// Return the filtered data
echo $filtered_data;
?>
