Our official documentation is now available on http://docs.php-opencloud.com. For SDKs in different languages, see http://developer.rackspace.com.
The PHP SDK should work with most OpenStack-based cloud deployments, though it specifically targets the Rackspace public cloud. In general, whenever a Rackspace deployment is substantially different than a pure OpenStack one, a separate Rackspace subclass is provided so that you can still use the SDK with a pure OpenStack instance (for example, see the OpenStack class (for OpenStack) and the Rackspace subclass).
Please visit our Installation instructions to find out more.
