To try the examples in this chapter, you will need access to a web server that understands PHP. I'll be using the Apache web server with PHP installed, but you can also use PHP with Microsoft's IIS, Netscape's web server, and many other servers.
I'll assume that you are comfortable reading simple HTML documents and have some basic familiarity with PHP in general. Most of this chapter focuses on the details of interacting with a PostgreSQL database from PHP. If you need more information regarding general PHP programming, visit http://www.zend.com.
