Query: Too Many Code Errors!!!

The first one-third of the book is pretty good. But beginning Chapter 12, you will begin to find too many codes which simply do not work. I guess the authors did not bother to test the codes even once. If you have any doubt about what I wrote, please go to a local bookstore and check the codes on pages 181-191 (files: "show_createtable. html," :do_showfielddef.php," and "do_createtable.php." I cannot understand why this book got such a good feedback. I regret buying this book a lot.
