What readers are saying about
Rails for PHP Developers
This is a thorough and approachable introduction to Ruby and Rails
for PHP programmers from fellow developers who are well-versed in
both Ruby and PHP.
Paul M. Jones
Lead Developer on the Solar Framework for PHP
As a PHP developer, I found the book focused well on the transition
from coding PHP to coding Ruby (and Rails) and that it gave great
examples of translating common PHP idioms to Ruby.
Matthew Weier O’Phinney
PHP Developer and Zend Framework Core Contributor
The quality of the writing is superb, the challenges and examples are
engaging, and the PHP to Ruby information is a valuable resource.
The exercises are nice, are short, and follow the topic well, giving
readers some creative time between each chapter.
Mislav Marohni´
c
Prototype JavaScript Framework Core Developer
This is an enjoyable book packed with great information and usable
examples. I like the organization of the book and the gentle, infor-
mal voice with which the authors cover many complex topics. It’s easy
to read, yet it has plenty of substance and depth to give the reader a
great introduction to Rails.
