What is the difference between PHP and JavaScript in the context of displaying notifications?
PHP is a server-side language, meaning it runs on the server before the webpage is loaded on the client's browser. JavaScript, on the other hand, is a client-side language that runs on the browser after the webpage is loaded. When it comes to displaying notifications, PHP can be used to generate dynamic content on the server-side before sending it to the client, while JavaScript can be used to create interactive notifications that appear on the client-side without the need to reload the page.
<?php
// PHP code to display a notification
$notification = "Hello, this is a notification!";
echo "<script>alert('$notification');</script>";
?>
