I would still go to the download link at the top of this page and download the source code that goes with the book to find out. My guess is since the book is newer that its examples comply with register_globals = off.
Other than that I don't understand your last statement, if you meant register_globals = on, then code written for register_globals = off works regardless of the register_globals setting! (The default value for the configuration directive is off BTW)
