What are common pitfalls when using dynamic menus in PHP, especially when including them in multiple pages?

Common pitfalls when using dynamic menus in PHP, especially when including them in multiple pages, include inconsistent menu updates across pages, inefficient code duplication, and difficulty in maintaining and updating the menu structure. To solve these issues, you can create a separate PHP file for the dynamic menu generation and include it in your main pages using PHP's include or require functions. 

// menu.php
<?php
$menuItems = [
    'Home' => 'index.php',
    'About' => 'about.php',
    'Services' => 'services.php',
    'Contact' => 'contact.php'
];

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

// index.php
<!DOCTYPE html>
<html>
<head>
    <title>Home</title>
</head>
<body>
    <?php include 'menu.php'; ?>
    <h1>Welcome to our website!</h1>
</body>
</html>

// about.php
<!DOCTYPE html>
<html>
<head>
    <title>About</title>
</head>
<body>
    <?php include 'menu.php'; ?>
    <h1>About Us</h1>
</body>
</html>
