An PHP 5 library for easy openid authentication. The stable version works only as a consumer, but there's an alpha version of a provider class avaiable in the git repository.

Features (of the consumer class):

• Easy to use. (you can code a functional client in less than ten lines of code)
• Uses curl if avaiable, php streams otherwise
• Supports both OpenID 1.1 and 2.0
• Supports Yadis discovery
• Supports only stateless/dumb protocol
• Works with PHP >= 5
• Generates no errors with error_reporting(E_ALL | E_STRICT)

The code is hosted on gitorious: http://gitorious.org/lightopenid The stable version can be downloaded here, but the newest one is available only from gitorious.

If you have any questions/problems regarding the library, send me a message.
