Rob Allen has posted a review of the Packt Publishing book "Learning PHP Data Objects" over on his blog today:

Packt Publishing recently sent me a couple of books to review. This post is about the second one I received, Learning PHP Data Objects by Dennis Popel. I was excited to receive this book as PDO underlies a lot of the Zend_Db_Adapter objects that I use in my day to day programming. It seemed like a good idea that I should know more about it.

He provides some good detail of what the book covers (chapter by chapter) as well as a summary including his recommendation for who should use the book and how they can best enjoy its contents.
