Summary

In this chapter, you've learned a number of things. Uploading files and file I/O are among the main things that aren't covered in most of the other chapters in this book. As you saw, the File and Directory classes give you easy ways to manipulate files and directories. And the File Field HTML object gives you an easy way to deal with user uploads.
