As of this writing, the symfony project has celebrated a significant milestone: its fourth birthday. In just four years, the symfony framework has grown to become one of the most popular PHP frameworks in the world, powering sites such as Delicious, Yahoo Bookmarks and Daily Motion. But, with the recent release of symfony 1.4 (November 2009), we are about to end a cycle.
This book is the perfect way to finish the cycle and as such, you are about to read the last book on the symfony 1 branch that will be published by the symfony project team. The next book will most likely center around Symfony 2.0, to be released late 2010. We have already published two books on symfony 1.3 and 1.4 recently: Practical symfony and The symfony reference guide. The former is a great way to start learning symfony as you learn the basics of the framework through the development of a real project in a step-by-step tutorial. The latter is a reference book that holds most any symfony-related configuration information that you may need during your day-to-day development.
More with symfony is a book about more advanced symfony topics. This is not the first book you should read about symfony, but is one that will be helpful for people who have already developed several small projects with the framework. If you've ever wanted to know how symfony works under the hood or if you'd like to extend the framework in various ways to make it work for your specific needs, this book is for you. In this way, More with symfony is all about taking your symfony skills to the next level.
As this book is a collection of tutorials about various topics, feel free to read the chapters in any order, based on what you are trying to accomplish with the framework. This book is special because this is a book written by the community for the community. Dozens of people have contributed to this book: from the authors, to the translators, to the proof-readers, a large collection of effort has been put forth towards this book. This book has been published simultaneously in no less than five languages (English, French, Italian, Spanish, and Japanese). This would not have been possible without the benevolent work of our translation teams. This book has been made possible thanks to the Open-Source spirit and it is released under an Open-Source license. This fact alone changes everything. It means that nobody has been paid to work on this book: all contributors worked hard to deliver it because they were willing to do so. Each wanted to share their knowledge, give something back to the community, help spread the word about symfony and, of course, have some fun and become famous. This book has been written by ten authors who use symfony on a day-to-day basis as developers or project managers. They have a deep knowledge of the framework and have tried to share their knowledge and experience in these chapters.
