This example explores what happens when you use header/footer includes for "deep content." The root directory for this example is named DeepContent. That's where this file, the header/footer files, and the other resources such as the stylesheet and graphic are located.

There is another folder named subfolder in the root directory. There are two pages in the subfolder, incorrect.php and correct.php, each of which need to use the common header/footer includes. The main issue is that the header/footer include files are in this directory, but the other content pages that need to use the header/footer are one directory deeper in the Web site in the subfolder.

The incorrect.php page will begin to explain this issue.
