How does the use of namespaces or file system structure impact the decision between dynamic and predefined routes in PHP?

When using namespaces or organizing files in a structured manner, it is easier to manage and maintain code, making it more scalable and organized. This can impact the decision between dynamic and predefined routes in PHP as predefined routes may be more suitable when using namespaces or a structured file system, as they provide a clear mapping between URLs and specific PHP files.

// Example of using predefined routes with namespaces in PHP

// index.php
require_once 'routes.php';

// routes.php
use MyNamespace\Controllers\HomeController;
use MyNamespace\Controllers\AboutController;

$route = $_GET['route'] ?? '';

switch ($route) {
    case 'home':
        $controller = new HomeController();
        $controller->index();
        break;
    case 'about':
        $controller = new AboutController();
        $controller->index();
        break;
    default:
        echo '404 Not Found';
}
