How can PHP developers ensure that links within a dynamically generated menu accurately reflect the file structure?

When dynamically generating a menu in PHP, developers can ensure that links accurately reflect the file structure by using the `$_SERVER['REQUEST_URI']` variable to dynamically set the active class on the current page link. This allows for the active link to be highlighted based on the current URL, providing a visual indication to users of their current location within the site. 

<?php
$current_page = basename($_SERVER['REQUEST_URI']);
$menu_items = array(
    'Home' => 'index.php',
    'About' => 'about.php',
    'Services' => 'services.php',
    'Contact' => 'contact.php'
);

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