The UcamWebauth PHP class provides an application agent for making authentication requests to the UcamWebauth server that can be called from PHP.
This could be useful if you wanted to embed authentication logic within a PHP web application. If all you want to do is Raven-protect some PHP-processed pages you'd probably be better using container-managed security such as that provided by the Raven Apache modules.
This module is really alpha-quality software and in need of further development. However it could be a useful starting point for anyone wanting to user Raven and PHP.
