What are the limitations of using PHP for real-time display, especially in comparison to JavaScript?

One limitation of using PHP for real-time display is that PHP is a server-side language, meaning it processes code on the server before sending the results to the client. This can result in slower real-time updates compared to client-side languages like JavaScript, which can update content instantly without needing to communicate with the server. To address this limitation, you can use AJAX (Asynchronous JavaScript and XML) in combination with PHP to achieve real-time updates on a webpage. AJAX allows you to send and receive data from the server asynchronously, enabling you to update content on the page without needing to reload the entire page. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])) {
    // Process the data received from the client
    $data = $_POST['data'];

    // Perform any necessary calculations or operations

    // Return the updated data to the client
    echo $updatedData;
}
?>
