XML-RPC Class Server is a really clever piece of code. It consists of a single file which you can drop in a directory full of PHP
.class.php files to instantly provide an XML-RPC interface to every class in the directory. Private methods that begin with an underscore are not included in the web service. Unfortunately the system requires PHP’s XML-RPC extensions to be enabled.
I’m not sure how this one snuck under the radar, but PHP now supports object overloading (as of version 4.2.0). It can be implemented by creating class methods
__call() and then applying the new overload() function to the class name. The documentation claims that
