In his "newbie findings" posted to his blog today, David Goodwin recounts his efforts to get SOAP an XML-RPC up and working with his PHP5 project and the wealth of documentation he found.

I'm no great expert on the inner workings of these protocols....there are probably secret manuals on SOAP/XmlRpc etc I/we failed to read somewhere. This is just a documentation of what I/we as "newbies" found ...

Resources in the list include things like the SCA SDO module from PECL, some examples of its usage, where it is used, what kind of transport layer the protocol allows and some of the functionality that the Zend Framework allows (including some sample code for a simple server and client).
