Incutio XML-RPC Library
The Incutio XML-RPC library is designed primarily for ease of use. It incorporates both client and server classes, and is designed to hide as much of the workings of XML-RPC from the user as possible. A key feature of the library is automatic type conversion from PHP types to XML-RPC types and vice versa. This should enable developers to write web services with very little knowledge of the underlying XML-RPC standard.
