How can AJAX be utilized to achieve the desired functionality in this scenario?

Issue: In this scenario, we want to dynamically update a webpage without refreshing it. AJAX can be utilized to achieve this functionality by sending asynchronous requests to the server and updating specific parts of the webpage with the response data.

<?php
// PHP code to handle AJAX request and return response
if(isset($_POST['data'])) {
    $data = $_POST['data'];
    
    // Perform necessary operations with $data
    
    // Return response back to AJAX request
    echo json_encode($response);
}
?>
