What is the difference between server-side PHP and client-side JavaScript in terms of updating content dynamically in a browser?

Server-side PHP is executed on the server before the page is sent to the client's browser, while client-side JavaScript is executed in the browser after the page has been received. This means that PHP can dynamically generate content on the server before sending it to the browser, while JavaScript can manipulate content already present in the browser. To update content dynamically in a browser using PHP, you would need to make a request to the server to fetch new data and then update the content on the page. 

<?php
// This PHP script fetches new data from the server and updates the content dynamically
$newData = fetchDataFromServer();
echo "<div id='dynamic-content'>$newData</div>";
?>
