How can metadata be used in PHP files to influence their position in the navigation hierarchy?

To influence the position of PHP files in the navigation hierarchy using metadata, you can add custom metadata tags to each PHP file that specify its position in the hierarchy. This metadata can include information such as the file's title, parent page, order in the navigation, etc. By parsing this metadata in your PHP code, you can dynamically generate the navigation menu based on the specified hierarchy.

<?php
// Example metadata in PHP file
/*
Title: About Us
Parent: Home
Order: 2
*/

// Parse metadata
$metadata = [
    'Title' => 'About Us',
    'Parent' => 'Home',
    'Order' => 2
];

// Use metadata to influence navigation hierarchy
// Generate navigation menu based on hierarchy
