What are the limitations of using PHP for this purpose compared to JavaScript?

One limitation of using PHP compared to JavaScript for front-end development is that PHP is a server-side language, meaning it is executed on the server before being sent to the client's browser. This can lead to slower loading times and less interactivity compared to JavaScript, which is executed on the client's browser. To improve interactivity and responsiveness in PHP, you can use AJAX to make asynchronous requests to the server without reloading the entire page. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])){
    $data = $_POST['data'];
    
    // Process the data
    
    // Return response
    echo json_encode(['success' => true, 'message' => 'Data processed successfully']);
}
?>
