Do you want your Perl code on one server to call your PHP functions on another? "Impossible!" you say? Not with XML-RPC. XML-RPC is a standard way for any application to make requests and recieve responses from methods written in any language. Interested? I knew you would be.
Well, that's it for now. It should be noted that you could make XML-RPC calls to the server we created with other XML-RPC implementations - you aren't limited to using PHP. Also it should be noted that you could make XML-RPC calls to other, non-PHP servers with PHP. That is the beauty of XML-RPC - it isn't restricted to one language or environment. Remember this when thinking of ways to implement it. Until next time - It's been fun!
