Why would you want to use any PHP router instead of writing the rewrite rules within an Apache VirtualHost file or a .htaccess file?
Overall, I'm not trying to discount anyone's work with developing PHP routers, but I'd like to understand the benefits of using them.
Also, restarting Apache after adding a route would get tedious during development.
A benefit of routing is that you can have a single point of contact in your app: a front controller. And you can place your route config in one place.
This router also has RESTful routing, detecting HTTP methods upfront that correspond to a predictable method name in a named class.
