Introduction to Including Files in PHP First, I want to say this is a beginner tutorial on including files with PHP. However, even if you are anintermediate or slightly beyond user, this tutorial may benefit you in some way because we are going todiscuss some security features. The main purpose of this tutorial is to kick off the new "Beginner" series of PHP tutorials. These tutorials willcover many of the common problems and questions, or misconceptions that we have seen on our forums andthroughout the net regarding PHP. This tutorial will be fairly short, so even if you've been working with PHPfor a while, you may still want to read on. In addition, this tutorial is not written to read or write to other files. It is simply written to show new usershow to include files properly. The constructs we will discuss in this tutorial should be used when you want to pull together pieces of code orsettings for your project. A common scenario would be a group of functions that you use throughout awebsite, or a class, or even a group of configuration settings, stored in a file such as a config.php with yoursite's pertinent information.
