The main decision I made for the challenge is to go for (*1)PhpLeague Route packages for routing/dispatching the application in a MVC pattern way. This choice give me a rapid structure to start working in the application based in a well tested/ trusted code.
The PhpLeague Route packages require an implementation of PSR-7 (*2)HTTP Message to work. This specification defines interfaces for the HTTP messages Psr\Http\Message\RequestInterface and Psr\Http\Message\ResponseInterface.
As per in the League\Route example I choose Zend\Diactoros implementation.
(*1) The PHPLeague is a distinguished group of developers who build solid, well tested PHP packages using modern coding standards for the community.
(*2) An HTTP message is either a request from a client to a server or a response from a server to a client.
Fundamental pieces of an HTTP request/response pair.

Basic Requests Verbs
- GET: fetch an existing resource. The URL contains all the necessary information the server needs to locate and return the resource.
- POST: create a new resource. POST requests usually carry a payload that specifies the data for the new resource.
- PUT: update an existing resource. The payload may contain the updated data for the resource.
- DELETE: delete an existing resource.
Basic Response Status Code
- 2xx: Successful
- 3xx: Redirection
- 4xx: Client Error
- 5xx: Server Error
