How can PHP variables be effectively utilized in conjunction with CSS for creating dynamic menu behavior in a website?

To create dynamic menu behavior in a website using PHP variables and CSS, you can use PHP to generate the menu items dynamically based on certain conditions or data. By assigning CSS classes to the menu items based on the PHP variables, you can style them differently or show/hide them as needed. This allows for a more flexible and dynamic menu structure on your website.

<?php
// Sample PHP code to dynamically generate menu items based on a condition
$menuItems = ['Home', 'About', 'Services', 'Contact'];
$currentPage = 'About'; // Assuming 'About' is the current page

echo '<ul>';
foreach ($menuItems as $item) {
    $class = ($item == $currentPage) ? 'active' : ''; // Add 'active' class to current page
    echo '<li class="' . $class . '"><a href="#">' . $item . '</a></li>';
}
echo '</ul>';
?>
