How can PHP and JavaScript be effectively combined to create a seamless user experience when opening new pages on a website?

To create a seamless user experience when opening new pages on a website, PHP can be used to dynamically load content without refreshing the entire page, while JavaScript can be used to handle client-side interactions and animations. By combining the two languages effectively, you can create a smooth transition between pages and enhance the overall user experience.

<?php
// PHP code to load content dynamically
if(isset($_GET['page'])) {
    $page = $_GET['page'];
    include($page . '.php');
} else {
    include('home.php');
}
?>
