$router = new Router(); // Define routes $router->get('/', 'HomeController@index'); $router->get('/posts', 'PostController@list'); $router->get('/posts/{id}', 'PostController@show'); // Get current route $currentRoute = $router->getRoute(); // Do something based on the current route if ($currentRoute == '/') { // Display the home page } elseif ($currentRoute == '/posts') { // Display a list of blog posts } elseif ($currentRoute == '/posts/{id}') { // Display a specific blog post }This example defines three routes for a blog application: the home page, a page listing all blog posts, and a page displaying a specific blog post based on its ID. The getRoute method is used to determine which of these pages the user is requesting, and then execute the appropriate code to display that page.
