How can the PHP code be optimized to improve the functionality of the navigation feature?

The PHP code for the navigation feature can be optimized by using a more efficient way of generating the navigation menu. One way to do this is by storing the navigation items in an array and then looping through the array to generate the menu dynamically. This approach can improve the code's readability, maintainability, and performance. 

<?php
// Define an array of navigation items
$navItems = array(
    'Home' => 'index.php',
    'About Us' => 'about.php',
    'Services' => 'services.php',
    'Contact' => 'contact.php'
);

// Generate the navigation menu dynamically
echo '<ul>';
foreach ($navItems as $label => $url) {
    echo '<li><a href="' . $url . '">' . $label . '</a></li>';
}
echo '</ul>';
?>
