Most of the scripts in this book are straight PHP. However, sometimes PHP and HTML are intermixed in the same script—and in many cases, on the same line. In those situations, a bold typeface differentiates PHP scripts from HTML, as shown in Listing 1.

You may use any of the scripts in this book for your own personal use, as long as you agree not to redistribute them. If you use any script in this book, you also consent to bear full responsibility for its use and execution and agree not to sell or create derivative products, under any circumstances. However, if you do improve any of these scripts or develop entirely new (related) scripts, you are encouraged to share them with the webbot community via the book's website.

The other thing you should know about the example scripts is that they are teaching aids. The scripts may not reflect the most efficient programming method, because their primary goal is readability.
