What are the limitations of integrating PHP and JavaScript functionalities in a web project?

One limitation of integrating PHP and JavaScript functionalities in a web project is that PHP is server-side while JavaScript is client-side. This means that PHP code is executed on the server before the page is sent to the client, while JavaScript code is executed on the client's browser. To overcome this limitation, you can use AJAX to make asynchronous requests to the server and update parts of the page without reloading it. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])){
    $data = $_POST['data'];
    
    // Process data here
    
    echo json_encode($result);
}
?>
