Upgrading to PHP 7
By Davey Shafik
Publisher: O'Reilly
Released: November 2015
PHP 7—the most dramatic update to the language in over a decade—has arrived. This O’Reilly report provides you with a short guide to the major changes in this new release, including a revamped engine (Zend Engine 3), a bunch of new features, and lots of language cleanup. You’ll learn about basic language changes, deprecated features, Unicode enhancements, changes in Object-Oriented programming, and other enhancements.

You’ll also discover why it’s taken more than 10 years for the first new major version of PHP since PHP 5 to appear—and what happened to version 6 in the meantime.

Get important details regarding changes to PHP 7, including:

Deprecated features, starting with alternative PHP tags and POSIX-compatible regular expressions
Uniform Variable Syntax, including consistency fixes and new syntax
Basic language changes, such as new operators, constant arrays, new functions, and regular expressions
Expectations and Assertions
Error handling
Enhancements to PHP’s Unicode, closure, and Generator features
Changes in Object-Oriented programming
Scalar type hints (perhaps the most polarizing and exciting new feature)

A brief description of new changes and features of PHP 7.0.
It assumed that you know PHP completely.

[Salvador · Rating 4 out of 5]

Concise a clear. A great way to catch up with the most important changes in PHP 7. For the ones not covered in the book, links to the relevant RFCs are given at the end.

Slightly dated as something mentioned in the book as "possible", are already implemented in PHP 7.1, but still a great way to get up to speed.

A very clear and concise introduction to (what was) the brand new PHP 7.0. We're already on 7.3, so some things have progressed beyond the boo, but I certainly found it a great refresher on some things I had forgotten, and a few things I never even knew about before.

Я бы назвал эту книгу: We have no time, upgrading to php 7! :)
Очень кратко и с примерами, без лишний воды и объяснения тривиальных вещей.

Libro muy interesante, se lee rápidamente (2 horas) y te pone al día de las novedades de php7.

Lo más interesante del libro es que lo explica tan bien que te dan ganas de empezar a picar código en php7.
