Acknowledgments

Thanks to Gabriele Lana and Francesco for being so closely related to the writing of this book. Without the help of Giada and some true friend, though, many things would be harder now: thank you all.

Thanks to Ideato, my company, and Jacopo, they let this project be true. Thanks to the PHP community for the great work they do every day to improve this great language. Thank to Chiara, without her patience and support nothing of this could be possible.
