XML-RPC

This is simply a copy of my old XML-RPC article (2005). I’ve done a bit of content editing when converting the article to this blog format, but still most of the content is unchanged.

1. Introduction

So you’ve decided to learn XML-RPC[1], or did the name just sound “freaky” and raised a little interest? If it did I suggest you read on, if you already know what XML-RPC is, then just skip the next intro part

1.1 What is XML-RPC

XML-RPC is a way to make web services, it packs the requests and responses in XML both the client and the server can understand.
For those who don’t know a web service is a function of some sort placed on the net (it could be a function to convert a string into all upper case letters, which we are going to make in the examples below). The smart thing is that, a web service can be programmed in any kind of language, and any other language can use it. Many big sites have a web service, for example Amazon has a web service that allows you to search books and information.
Another smart thing about XML-RPC (and to my knowledge all other web services), is that they can be run from a web server. Not only is this smart, because you don’t need to install some high-end server dedicated to the purpose. But you don’t have to worry about firewalls.

1.2 Installing XML-RPC

If you’ve installed an extension before, this should be no problem at all, just install the XML-RPC extension. But if this is your first time, the following links will help a bit:
Windows users: http://www.php.net/manual/en/install.windows.extensions.php
Unix users: http://www.php.net/manual/en/install.unix.php
OS X users: http://www.php.net/manual/en/install.macosx.php
For you guys(and gals) who compile PHP: –with-xmlrpc. Read more »
