How can PHP be used to dynamically highlight active menu items based on the current page in a website?

To dynamically highlight active menu items based on the current page in a website, you can use PHP to check the current URL against the URLs of each menu item. If there is a match, you can apply a CSS class to that menu item to highlight it as active. 

<?php
$current_url = $_SERVER['REQUEST_URI'];

$menu_items = array(
    'Home' => '/',
    'About' => '/about',
    'Services' => '/services',
    'Contact' => '/contact'
);

foreach ($menu_items as $label => $url) {
    if ($current_url == $url) {
        echo '<li class="active"><a href="' . $url . '">' . $label . '</a></li>';
    } else {
        echo '<li><a href="' . $url . '">' . $label . '</a></li>';
    }
}
?>
