ABSTRACT
This chapter discusses Really Simple Syndication (RSS) and PHP Data Objects (PDO). RSS provides an easy way to share and view content on the Internet and is written in XML. It was designed to show selected data. RSS is often called a news feed or RSS feed. People can check a website at any time to see updates because an RSS feed is linked to a database. The PDO extension defines a lightweight, consistent interface for accessing databases in PHP. PDO provides a data-access abstraction layer, which means that the same functions are used to issue queries and fetch data regardless of the database software. This chapter provides instructions to create an RSS feed, and to use the PDO extension to communicate with the Oracle database. PDO provides a data-access abstraction layer, which means that, regardless of database, the same functions are used to issue queries and fetch data. So, PDO provides an object-oriented alternative to APIs.
