How can PHP be used to dynamically change link styles based on the current page?

To dynamically change link styles based on the current page in PHP, you can use a combination of PHP and HTML. One way to achieve this is by adding a CSS class to the active link based on the current page URL. This can be done by checking the current page URL against each link's URL and adding the active class if they match. 

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

function isActive($page) {
    global $current_page;
    if ($page === $current_page) {
        echo 'active';
    }
}
?>

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