From the phpblog on the IBM developerWorks website today, there's a quick new tutorial focusing on the use of the Service Component Architecture functionality in PHP to interface with the web service API that eBay offers.

I've just made the first code drop to support calling eBay Web services using the Service Component Architecture. Anyone who's tried calling the eBay soap APIs will know there are quite a few hoops to jump through to get it working. [...] The SCA eBay soap support hides this complexity by allowing you to specify the information as configuration parameters and then it makes sure the right things are placed in the header or the URL.

A code example is included that makes a connection to the web service, calls the GetSearchResults action for the query of "ipod" and, upon getting the results back, loops through them to display them to the page.
