Zend_Service_Yahoo is a simple API for using many of the Yahoo! REST APIs. Zend_Service_Yahoo allows you to search Yahoo! Web search, Yahoo! News, Yahoo! Local, Yahoo! Images. In order to use the Yahoo! REST API, you must have a Yahoo! Application ID. To obtain an Application ID, please complete and submit the Application ID Request Form.

Zend_Service_Yahoo enables you to search the Web with Yahoo! using the webSearch() method, which accepts a string query parameter and an optional second parameter as an array of search options. For full details and an option list, please visit the Yahoo! Web Search Documentation. The webSearch() method returns a Zend_Service_Yahoo_WebResultSet object.

<?php
require_once 'Zend/Service/Yahoo.php';
$yahoo = new Zend_Service_Yahoo("YAHOO_APPLICATION_ID");
$results = $yahoo->webSearch('PHP');
foreach ($results as $result) {
    echo $result->Title .'<br />';
}
?>       

You can search for Images with Yahoo using Zend_Service_Yahoo's imageSearch() method. This method accepts a string query parameter and an optional array of search options, as for the webSearch() method. For full details and an option list, please visit the Yahoo! Image Search Documentation.

The following classes are all returned by the various Yahoo! searches. Each search type returns a type-specific result set which can be easily iterated, with each result being contained in a type result object.
