What are the differences between PHP and JavaScript in terms of real-time content updates on a webpage?

PHP is a server-side language, meaning that it runs on the server before the webpage is sent to the client's browser. This makes it suitable for handling tasks such as database queries and processing form submissions. On the other hand, JavaScript is a client-side language, allowing for real-time updates on a webpage without the need to reload the entire page. To achieve real-time content updates on a webpage using PHP, you can utilize AJAX (Asynchronous JavaScript and XML) to send requests to the server and update specific parts of the page dynamically. 

<?php
// PHP code to handle AJAX request
if(isset($_POST['data'])){
    $data = $_POST['data'];
    
    // Process the data as needed
    
    // Return updated content
    echo $updatedContent;
}
?>
