I loved this website, AWS Zone is a very original way to work with Amazon Web Services. The website is a simple interface to the different AWS via WSDL offering an automated interface to query the service or consult the documentation. The service covered by the service are :

- Amazon E-Commerce Service
- Amazon S3 (Storeage)
- Alexa Web Information Service
- Alexa Top Sites
- Alexa Web Search Platform
- Amazon Mechanical Turk Requester
- Amazon Historical Pricing

Creating such code in PHP is very easy, but i find it very useful too. Netfactory.dk have small snippets written in PHP5 check it out if you are interested into working with PHP5 and Web Services.
