How can the active menu item be highlighted in a PHP list navigation?

To highlight the active menu item in a PHP list navigation, you can add a conditional statement to check if the current page matches the menu item. If it does, you can apply a CSS class to highlight it. 

<?php
$current_page = basename($_SERVER['REQUEST_URI']);

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

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