If you need to get going with PEAR::DB quickly this is a great way to do it. It's a short book, but gets right to the point. You are expected to know PHP and how to program. So there is no hand holding. The structure is: you are given a code snippet on how to do it and a brief explanation. It just gets right down to brass tacks explaining PEAR::DB. The explanation (which includes basic install instructions) extends for the first 29 pages. After that its just function explanations.
The caveat to all this is that it is a great concise book if you need to learn PEAR::DB quickly, ie it is going to be used on the project I am working on right now which is due yesterday. If however, you have plenty of time and just want to learn PEAR::DB the cost is probably too high and you are better off learning from tutorials and other info on the web.
This is the second book on this topic I have ordered. I have been in search of a "beginning" book that will bridge the gap between the scripts and the implementation thereof. Steps A - B have been more like steps D, J - L, then Q. Fragmented at best. Hopefully, someday, someone will produce a book for someone like me, who admittedly needs to be hand held and walked through this topic.
