$app->get('/users/{id}', function ($request, $response, $args) { // logic to display user details });
$app->post('/users', function ($request, $response) { // logic to create a new user });This example defines a route for creating a new user. The HTTP method used is POST. Both examples are taken from Slim, a popular PHP micro-framework. The registerRoutes function is part of the Slim\App package library. In summary, the Application registerRoutes function is a powerful tool for defining and managing routes in a PHP web application. It simplifies the process of handling HTTP requests and responses and is a major component of popular PHP frameworks.
