To follow along with the exercises and discussions in this book, you will need a working Drupal 7 installation and access to the Internet. Your Drupal installation may be remote (that is, hosted on a web server) or, preferably, a local installation on your PC or laptop.

Some experience with the PHP programming language is recommended before tackling the programming exercises, but this is not an outright requirement as the code samples have been thoroughly tested. The programming tasks covered within this book can be coded with any standard plain text editor, although a programming editor is advised.
