If you host downloadable content on SDF, you may want to get an idea of how many people have downloaded things and which are the most popular. In this tutorial, I will focus on an example of tracking PDF formatted ebooks. After completing this tutorial, you should be able to modify things to suit your needs, even if your downloads are not ebooks. You will need to have PHP access to do this, so check your membership level before you get started.

For the impatient and the PHP gurus in the audience, I will show the entire script first. After that, I'll pick it apart and explain each section.
