What is the limitation of using PHP in controlling browser behavior?

One limitation of using PHP to control browser behavior is that PHP is a server-side language and cannot directly manipulate client-side actions like clicking a button or submitting a form. To overcome this limitation, you can use AJAX (Asynchronous JavaScript and XML) to send requests to the server without refreshing the page, allowing for dynamic updates to the browser. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])){
    // Process the data from the client
    $response = "Data processed successfully";
    echo $response;
}
?>
