| 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 a mixture of container-managed

| Note that versions of this library prior to 0.51 contained a security vulnerability, in that they used the value of the 'Host' header of an HTTP response to validate 'Authentication response' messages. The Host header is under the control of a potential attacker and, by altering it, an attacker might be able to replay an existing Authentication Response message against a site that relies on the PHP library. This problem is resolved in version 0.51, at the expense of an incompatible change: a securely-obtained host name must be supplied before invoking the library functions.

| This problem also affected versions of this library identified as 0.6 and 0.61 that were distributed only as part of Raven authentication support for phpBB3 in early 2008, but updated phpBB/Raven kits (with V0.62, which provides the security fix) are available.

| [NB Version 0.51 is '''not''' suitable as a replacement for 0.6/0.61, as the phpBB modifications require newly-added functionality that doesn't exist in 0.51. Conversely, the changes in 0.6/0.61/0.62 broke the old interface (as provided by 0.51 and earlier), so they cannot be used with software that uses the old interface. It is hoped that at some point in the future, a unified version will support both the old and new functionality.]
