On the symfony blog today there's a new post that points out some of the excellent books you can get covering the framework in general and a bit more specific topics inside.

I love books! And I buy a lot of them. When I was young, I dreamt about writing a book. And thanks to symfony, my dream became true two years ago with the publication of the "Definitive Guide to symfony" book, published by APress. This book was co-authored with Francois Zaninotto and it covers symfony 1.0. Last year, I wrote yet another book on symfony, "Practical symfony", to cover the new symfony 1.2 version. This book has been a huge success online, and was self-published on lulu.com.

The books mentioned are:

• Practical symfony 1.2 for Doctrine - second edition
• Practical symfony 1.2 for Propel - second edition
• Symfony : Mieux developper en PHP avec Symfony 1.2 et Doctrine
• Pre-release chapters of the "Symfony 1.2 Reference Guide": settings.yml Configuration File, factories.yml Configuration File and Events.
