PHPBuilder.com has moved on in their "Using XML: A PHP Developer's Primer" series with this new tutorial posted today - part four, a look at XML-RPC, PHP, and Javascript.
In this article we will demonstrate how PHP can be used to call upon web services provided by third part sites via an XML-RPC server. We will also show you how to create your own XML-RPC and use client-side Javascript to invoke procedures in your PHP scripts.
They start with an overview of what XML-RPC is, how it works, and some sample calls to show you how it's done. From there, they show you how, using the PEAR XML-RPC client, you can connect to Flickr and grab picture information for a specific user. And keep an eye out for the next article in the series. It will cover the other half of the equation - the creation of your own XML-RPC server.
