Are there best practices for using PHP to indicate active links on a webpage?

To indicate active links on a webpage using PHP, you can compare the current URL with the link URL and add a CSS class to highlight the active link. This can be achieved by checking if the current URL matches the link URL and adding a specific class to the active link. 

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

function isActive($url) {
    global $current_url;
    if ($url === $current_url) {
        return 'active';
    } else {
        return '';
    }
}
?>

<ul>
    <li><a href="/" class="<?php echo isActive('/'); ?>">Home</a></li>
    <li><a href="/about" class="<?php echo isActive('/about'); ?>">About</a></li>
    <li><a href="/services" class="<?php echo isActive('/services'); ?>">Services</a></li>
    <li><a href="/contact" class="<?php echo isActive('/contact'); ?>">Contact</a></li>
</ul>
