AmazonLib is an API for Amazon.com's Web Services. It is written in PHP. It simplifies the process of writing applications using Amazon's Web Services. AmazonLib consists of four main components: 1) nurest.php -- a REST parser class which parses Amazon's XML responses into an associative array. 2) amazonrest.php -- a REST API class for all of the API calls in AWS 3.0. 3) amazonsoap.php -- a SOAP API like amazonrest.php. I use, and include, Dietrich Ayala's nusoap.php SOAP library. 4) amazonseller.php -- a beta API for amazon.com's seller interface. AmazonLib has a few nice features. It should run on any PHP4 distribution and it will also log most error messages. Like nusoap, it's distributed under the GNU Lesser Public License.
