What are some best practices for incorporating PHP into a website's main menu to ensure smooth functionality and user experience?

Issue: When incorporating PHP into a website's main menu, it is important to ensure smooth functionality and a good user experience. One common approach is to use PHP to dynamically generate the menu items based on certain conditions or user roles. This can help keep the menu up-to-date and relevant for users. PHP Code Snippet:

<?php
// Define an array of menu items with their respective links
$menuItems = array(
    'Home' => 'index.php',
    'About Us' => 'about.php',
    'Services' => 'services.php',
    'Contact Us' => 'contact.php'
);

// Loop through the menu items and output them as list items in an unordered list
echo '<ul>';
foreach ($menuItems as $menuItem => $link) {
    echo '<li><a href="' . $link . '">' . $menuItem . '</a></li>';
}
echo '</ul>';
?>
