The book is about how to become developer super hero and gain amazing productivity powers to develop stunning, native cross-platform mobile apps from the same codebase for Android and iOS! The foreword was written by David Intersimone and I'm very proud about it, because I have the deepest respect to David I!

One of the most important (and controversial) new features in PHP 7 is the option to use strict data types, in the form of parameter and return type declarations.
