If you don't have the first edition, get the second. If you have the first edition - get the second, it really is that good.

The book has expanded on the original with more examples and more pitfalls as well as new chapter on XML and updates on the mod_perl (for the Apache http server) and handling unicode.

I had no problems with compiling and running the code and the explanations of the code and where it can go wrong left me in no doubt that the authors know what they are talking about. Highly Recommended
