A new version of XML-RPC for PHP has been released, incorporating new helper functions in addition to bug fixes.
Version 1.0b8 adds the following features:
- xmlrpc_debugmsg() method allows sending of debug info in comments in
the return payload from a server
- xmlrpc_encode() and xmlrpc_decode() translate between xmlrpcval
objects and PHP language arrays
Bug fixes include the correct sending of "Content-length" header and whitespace handling issues. A full changelog is available online, as is documentation.
