This library now implements draft 20 of OAuth 2.0. The client is still only draft-10.
This version of oauth2-php is a fork of https://github.com/quizlet/oauth2-php with the following changes:
- No more require(_once)
- PSR-4 autoloading compatible
- Uses HttpFoundation Request and Response for input/output
- More testable design
- Better test coverage
(pull request is pending)
http://code.google.com/p/oauth2-php/ is the original repository, which seems abandonned.
