Diving into PHP7

About the Book

The book will take a course through what I consider killer features of PHP7 to the more mundane new features. I thought it made sense to split these up because not everybody has the stamina to launch through an exhaustive list of new features.

Then we’ll look at how to get PHP7 up and running on your machine. We’ll try to make sure that you’re able to revert to your current configuration, but please do make sure you have proper backups so that you can restore your settings if you find PHP7 is not compatible with your project.

Finally we’ll be examining how to migrate your existing code to run on your new PHP7 interpreter. Part of the reluctance to upgrade to PHP7 comes from the uncertainty of wondering “will it work”. We’ll look at ways to deal with this and move forwards with confidence.

Causes Supported

Electronic Frontier Foundation

Defending your civil liberties in a digital world.

Based in San Francisco, EFF is a donor-supported membership organization working to protect fundamental rights regardless of technology.

From the Internet to the iPod, technologies are transforming our society and empowering us as speakers, citizens, creators, and consumers. When our freedoms in the networked world come under attack, the Electronic Frontier Foundation (EFF) is the first line of defense. EFF broke new ground when it was founded in 1990—well before the Internet was on most people's radar—and continues to confront cutting-edge issues defending free speech, privacy, innovation, and consumer rights today. From the beginning, EFF has championed the public interest in every critical battle affecting digital rights.
