I’m frustrated by not being able to access the source code for this book. When I try to open the zip file of source code, my computer says it’s empty. When I try to open it instead of saving it, I get an error message saying it’s an invalid request.

Since you don’t put the source code in your book, I’m reliant on getting this information and the image files from you. Can you please fix this problem!

Thank you!

However, as a general principle, I think there is a serious problem regarding computer book publishing. Too many books are competing for a relatively small number of sales. As a result, the royalties an author earns from a book are too small for most people to survive by doing nothing else but write. That leads to chapters being rushed. Mistakes should be picked up during the editorial process, but most editors are not technical experts.

If fewer books were produced, and more attention paid to quality control, everyone would benefit. The readers would get good quality books, the authors would get a better return for the time and effort spent on writing a book, and the publishers of good books would also make a profit. Unfortunately, publishers seem hell bent on flooding the market with as many titles as possible, in the hope that a handful will be profitable enough.

Your book is excellent and does a number of things for me. I enjoy your writing style, it encourages me to greater heights, shows me a huge number of things that can be done and enables me to use the techniques for other tasks. I have really enjoyed the book. Thanks again.

Keep up the great work!

I always recommend your titles to friends diving into PHP.
