Slim VS phroute

Slim is a micro PHP framework used for web development with 11.7k stars and 2k forks on GitHub. It has a simple and intuitive API development process. It is a micro-framework, meaning you only get a minimum of support for HTTP requests and forwarding requests to appropriate controllers. So the question is, why should you choose a micro-framework? Because it offers you flexibility and high extensibility.

Slim 4, a minimalistic PHP micro-framework, offers middleware support to easily add CORS headers. Middleware in Slim acts like a series of layers through which your app sends a request. One such layer can be responsible for adding CORS headers.

SlimPHP 3 Skeleton app shows this as well: https://github.com/slimphp/Slim-Skeleton/blob/3.1.8/public/index.php

How hard did you look? There are plenty out there. FastRoute, Phroute, based on FastRoute, with basic middleware, League/Route - routing with middleware, using FastRoute, PSR 7 & 15, Slim Framework, at it's core, it like League/Route, etc. None of these require a full framework to use.

You can have the container call in a config folder with a file called dependencies or how ever you want. A few existing examples of this is here - Slim calls this app/dependencies in this skeleton project and Odan's Skeleton has this as config/container in their project.

Maybe use this if you don't like to dive into bigger frameworks: https://www.slimframework.com/

Go for Slim: https://www.slimframework.com/

The router code for this could look like (using Phroute for the example). The functions could be sent to classes if you have that setup.

Finally, add a router to map all of this out. You could use a library, some one noted FastRoute, there a few out there like Phroute for one.

Using a router library like FastRoute or Phroute to show the example

Someone mentioned FastRoute. You can look at Phroute as well - https://github.com/mrjgreen/phroute

Additionally, you lose the checks at the top of those files (here' and here if you implement middleware. Here is one example using pretty URLs and a router library. Using Phroute to show the example - pseudo code to illustrate:

Using Phroute to show the example

This can be refactored. If you use start using a router and middleware, this can be done as middleware (or a before/after filter for older libraries - See the Filter Group section on this library for example usage - https://github.com/mrjgreen/phroute)
