Are there any common pitfalls to be aware of when incorporating PHP scripts with CSS styling for navigation elements?

One common pitfall when incorporating PHP scripts with CSS styling for navigation elements is not properly separating the PHP logic from the HTML/CSS structure. To avoid this, it is recommended to use PHP to generate the necessary HTML markup for the navigation elements and then apply CSS styling to those elements.

<?php
// PHP script to generate navigation elements
$navItems = array(
    'Home' => 'index.php',
    'About' => 'about.php',
    'Services' => 'services.php',
    'Contact' => 'contact.php'
);

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