What potential pitfalls should be considered when including subcategories in PHP switch statements for webpage navigation?

When including subcategories in PHP switch statements for webpage navigation, potential pitfalls to consider include the complexity of managing multiple nested switch cases, the risk of code duplication or redundancy, and the potential for errors in handling different levels of subcategories. To avoid these pitfalls, consider using a more flexible and scalable approach such as using arrays or objects to map navigation paths to corresponding actions. 

// Example of using arrays to map navigation paths to actions

$navigation = [
    'home' => 'home.php',
    'about' => 'about.php',
    'products' => [
        'category1' => 'category1.php',
        'category2' => 'category2.php',
    ],
    'contact' => 'contact.php',
];

$path = 'products/category1';

$parts = explode('/', $path);
$current = $navigation;

foreach ($parts as $part) {
    if (is_array($current) && array_key_exists($part, $current)) {
        $current = $current[$part];
    } else {
        echo "404 Not Found";
        break;
    }
}

include $current;
