How can PHP be utilized to automatically detect the current page for navigation styling purposes?

To automatically detect the current page for navigation styling purposes in PHP, you can use the `$_SERVER['REQUEST_URI']` variable to get the current page URL and compare it with the navigation links. By comparing the current page URL with the navigation links, you can add a specific CSS class to the active navigation link to style it differently. 

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

// Navigation links
$nav_links = array(
    '/index.php' => 'Home',
    '/about.php' => 'About Us',
    '/services.php' => 'Services',
    '/contact.php' => 'Contact Us'
);

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