One of the reasons WordPress is the most popular content management system (CMS) is that you don't need to know PHP code to use it. That's to say, you can use WordPress easily without ever looking at any of the code or template files contained within it. However, if you want to tweak the settings of your WordPress theme (flip to Book VI) or the code of a particular plugin (see Book VII), you need to understand some basics of how PHP works. But don't worry; you don't need to be a PHP programmer.
This chapter introduces you to the very basics of PHP and MySQL, which is the database system that stores your WordPress data. After you read this chapter, you'll understand how PHP and MySQL work together with the WordPress platform to serve up your Web site in visitors' browsers.
