Indeed, PHP is part of that industry. Some parts of the PHP eco-system are even leading the way, believe it or not.

Laravel is the best example for this, with spin-offs in several other languages. (Fair notice: many of the ideas in Laravel are not new, but borrowed/inspired from C#, rails and others)

* Node.js frameworks inspired by Laravel: http://www.adonisjs.com/, https://quorrajs.org/

* Python: http://www.pylonsproject.org/projects/pyramid/about, https://github.com/aacanakin/glim

* Java: http://wings.loonydev.com/

and so on

In other news, the `trait` type was recently popularized by PHP and can now be found in many languages: https://en.wikipedia.org/wiki/Trait_(computer_programming)
