What are the potential challenges of using PHP for real-time updates on web pages compared to other scripting languages?

One potential challenge of using PHP for real-time updates on web pages is that PHP is a server-side language, meaning it requires a page refresh to see updates. To overcome this limitation, you can use AJAX (Asynchronous JavaScript and XML) to make asynchronous requests to the server and update specific parts of the webpage without reloading the entire page. 

<?php
// PHP code to handle AJAX request and send back updated data
if(isset($_POST['data'])) {
    // Process the data and generate updated content
    $updatedContent = "New content here";
    
    // Send back the updated content
    echo $updatedContent;
}
?>
