You will be configuring the PHP interpreter with a few extra modules one of which is Boutell s GD library GD SDK . The GD SDK allows you to generate and manipulate images on the fly which I consider to be very important in the development of games. If you would like to install other modules feel free. The majority of the installs are very similar. Let s get to it The Platforms Since PHP is not OS dependent we will be installing and configuring PHP for UNIX and Windows. When you talk about UNIX the Web server of choice is Apache. You can configure PHP in two different ways when you install on Apache. As a CGI Interpreter. As a Apache module. 23 24 Chapter 2 Waging the Configuration War Note You can only configure PHP as an Apache module with the Apache server.

This means two things to you 1 you get a performance boost when interpreting pages but 2 you get screwed if a page goes haywire. If one of your PHP pages goes haywire when running in the same memory space as the Apache server the Apache server will halt.
