What is the purpose of the routing system being created for the Content Management System in PHP?

The purpose of the routing system in a Content Management System (CMS) created in PHP is to map URLs to specific functions or controllers, allowing for dynamic content generation based on the requested URL. This helps in organizing the codebase, improving code reusability, and enhancing the overall user experience by providing clean and user-friendly URLs.

// Sample PHP routing system implementation for a CMS
$route = $_GET['route'] ?? 'home';

switch ($route) {
    case 'home':
        include 'pages/home.php';
        break;
    case 'about':
        include 'pages/about.php';
        break;
    case 'contact':
        include 'pages/contact.php';
        break;
    default:
        include 'pages/error.php';
        break;
}
