XML-RPC in PHP
If you are looking for an implementation of XML-RPC in PHP, I can recommend Keith Deven’s XML-RPC Library for PHP (v 2.5) as an excellent solution. Although the XML-RPC for PHP open source project is more comprehensive and more widely used (I think), the disadvantage that I saw was that it was far too complex to actually use, especially when building the server. Keith Devens’ solution, by contrast, is far cleaner, simpler and easier to understand. And the more software I write, the more I appreciate simplicity as a virtue.

What isn’t so nice is the XML-RPC spec itself, which is verbose and makes for big XML payloads compared to plain XML.
