The Chomp online feed reader is now beginning to take shape. Users can register for accounts and subscribe to feeds, as well as read them. Now, users can export saved entries as PDF documents. To make this happen, you used the Zend Framework's
Zend_PDF component to create a new PDF, add shapes, graphics, and text, and save it. You also looked at outputting the PDF directly to the browser and at using an existing PDF, rather than creating a new one.
In addition, you looked at ways to get around some of the problems with manually building PDFs, such as an inability to line-wrap automatically and an inability to add new pages to the document automatically.
In Part 6, learn how to send a user an e-mail when a favorite feed is updated.
