Overall, this book is a great introduction to PHP. The code examples are useful, and I have yet to find one that has errors in it. There are some formatting nuances in PHP that the author doesn't go into, and that would have helped. But the code from the CD-ROM worked fine when I ran into problems, and was useful in making comparisons.
My biggest problem came in setting up MySQL -- I'm using Win2k and, like another reviewer, there are some real glitches that the book doesn't discuss. Luckily, I have enough experience that I was able to find my way around them, but more installation instructions would have helped. While this book is targeted at PHP, using MySQL is essential in how it's being implemented here, and therefore more information should have been included. There are a number of sites online dealing with PHP and MySQL (and also Apache Server, which comes with it), so finding what you need isn't too far away.
I had one major concern regarding the installation files: When I scanned the CD, I found that one of the files on the Linux section had a virus in it...I don't know whether I got the warning because of Linux's use of multiple extensions or not, but I will be emailing the author/publisher regarding this.
Overall, it's a great beginner's book, and a good intro to most of the types of PHP coding that you may find useful. When you're done with this one, you can move on to subjects like how to set up effective databases, normalization, etc., which are beyond the scope of this book. And if you have experience working with other online databases, you'll find this book a breeze to work through and a great place to get you going for more aggressive projects...
