Zend_Service_Amazon_Query provides an alternative API for using the Amazon Web Service. The alternative API uses the Fluent Interface pattern. That is, all calls can be made using chained method calls. (e.g., $obj->method()->method2($arg))

The Zend_Service_Amazon_Query API uses overloading to easily set up an item search and then allows you to search based upon the criteria specified. Each of the options is provided as a method call, and each method's argument corresponds to the named option's value:

<?php
    require_once 'Zend/Service/Amazon/Query.php';
    $query = new Zend_Service_Amazon_Query('MY_API_KEY');
    $query->Category('Books')->Keywords('PHP');
    $results = $query->search();
    foreach ($results as $result) {
        echo $result->Title .'<br />';
    }
    ?>       

Zend_Service_Amazon_Item is the class type used to represent an Amazon item returned by the web service. It encompasses all of the items attributes, including title, description, reviews, etc.
