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:

• Namespaced
• No more require(_once)
• PSR-0 autoloading compatible
• Uses HttpFoundation Request and Response for input/output
• More testable design
• Better test coverage

(pull request is pending)

https://github.com/quizlet/oauth2-php is a fork of http://code.google.com/p/oauth2-php/ updated against OAuth2.0 draft 20, with a better OO design.

http://code.google.com/p/oauth2-php/ is the original repository, which seems abandonned.
