The Definitive Guide to symfony - book cover“The Definitive Guide to symfony” is part of the official documentation of the symfony PHP Web framework.

This book can be read online, and is published under the GFDL license. Hhowever, reading a printed copy allows a better in-depth understanding of this framework. It is very well written, with a lot of examples. It is directed to either newbies wanting to begin developing web applications with symfony, or experts, as it can be used as a quick reference for specific aspects of the web framework.

Though the book was updated online for newer releases of symfony, no new revision was printed at the moment of writing. Symfony 1.0 remains the preferred stable branch for long term projects, with its 3 years support (until January 2010).

For those who like having a book in their hands and want to use a simple but powerful web framework, here is the Amazon link for buying a printed copy.
