“Upgrading to PHP 7” book review:

PHP 7—the most dramatic update to the language in over a decade—has arrived.

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.
