Hi @twiggy99
Maybe what your are looking for are actually Symfony Components, especially Http Foundation and Routing.
- http://symfony.com/doc/current/components/http_foundation.html
- http://symfony.com/doc/current/components/routing.html
If you dive deeper into the Laravel's source code, you will find that Laravel uses it under the hood.
Or you can explore other, very efficient routings library such as
- https://github.com/klein/klein.php
- https://github.com/nikic/FastRoute
- https://github.com/c9s/Pux (as php extension)
There are also some posts out there, that try to benchmarks well-known routers - feel free to explore followings websites
