Over on PHP Magazine's website today, there's a new review of a book that all PEAR users (and even those looking to get into it) will find quite helpful.

About Comprehensive PHP PEAR::DB: If you are looking to make your software portable across multiple databases, you may want to consider using PEAR::DB, an OO-style API that uses one common interface across many of the databases in use today. In his new book, Comprehensive PHP PEAR::DB, Blake Schwendiman provides readers with a complete review, informing his readers which features work, which are still in development, and which are deprecated. The book will be most useful for developers who have a working knowledge of databases, and who have already decided to use PEAR::DB.

Overall, the review states that the book, while a good resource/tool for those using PEAR:DB, still could be better. It is, however, an important contribution to the field. The very act of writing about PEAR helps legitimize the PEAR respository, and this book will likely go far in convincing the undecided that PEAR::DB is worthy of consideration.
