How can PHP be leveraged to ensure proper bookmarking functionality while keeping the URL unchanged in the address bar?

To ensure proper bookmarking functionality while keeping the URL unchanged in the address bar, you can utilize PHP to implement URL rewriting. By using PHP to handle the routing of requests, you can map user-friendly URLs to specific PHP scripts without changing the URL in the address bar. This allows for bookmarking of pages while maintaining clean and consistent URLs. 

// .htaccess file to enable URL rewriting
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

// index.php file to handle routing
<?php
$url = isset($_GET['url']) ? $_GET['url'] : '';
switch ($url) {
    case 'home':
        include 'home.php';
        break;
    case 'about':
        include 'about.php';
        break;
    default:
        include '404.php';
        break;
}
?>
