I am a PHP programmer and I want to learn how to use the RESTful API.
Do not create REST applications, namely, contact REST services and receive a response from them.
I used to think that Google Maps API, Facebook API or Sphinx search engine are based on REST principles, but I read the documentation and I got the impression that these services have an API that is far from being RESTful.
So please, tell me API examples based on REST architecture with good documentation.
