This is a PHP Enum Solution using classes and type hinting. Also you can build a taxonomies of enums!
An enumeration type, "enum" for short, is a data type to categorise named values. Enums can be used instead of hard coded strings to represent, for example, the status of a blog post in a structured and typed way.
In July 2019, I wrote a gist searching a solution for this.

Library for JavaScript and PHP, that allow mapping the PHP functions, static methods of classes and arbitrary data. This class provides a simpler solution to return registered data without having to register a specific function.
A "way" is different to a "route". We need a path for found a specific resource, but we need a way for do something. This library follow this concept when implements the routing and control of PHP application.
Ways is a class that adapts the concept of SOA to the architecture of a PHP application, and tries to integrate the parts of a hybrid system.
With Ways you should think more about "control points" than on controllers of an MVC pattern. Control points are activated when they are needed, ie on demand, depending on the definition you have made.
