To demonstrate how to use this component, we're going to create a basic script that allows a user to log in to their Twitter account and post a status update. Twitter is currently phasing out "basic authentication" and requiring all third-party web and desktop applications use OAuth. This article can be used as a starting point for creating (or updating existing) Twitter API apps. We will also be using the Zend_Service_Twitter component, as I covered in a previous screencast.

He talks some about how OAuth works and how to use the component, along with Zend_Db, to create a simple comsumer script that connects to Twitter and posts a message to Twitter as the user that's authenticated.
