Now that PHP 7 has been released, it's time to catch up with what this new major version has to offer. In this tutorial from SitePoint you can learn about what the latest features and changes are in this release (including what happened to PHP 6).

PHP 7, the next version of the world’s most popular programming language, has been released. We’d love to shoot fireworks and get drunk with our newfound power (seriously, the language is in the true big leagues now, functionality and performance-wise) but we’re sure the rest of the internet will do this for us. Instead, we’ll focus on compiling a (perpetually up to date) list of resources to get started with version 7 – posts describing what’s new, books helping you kick things off, and more.

The post starts by answering the "what happened to PHP 6?" question, listing a few resources with some more information on the topic. Following this it gets into the "what's new" of PHP 7 including:

• Links to guides to the features themselves
• Tools to help you get a PHP 7 environment set up
• Other PHP 7-related tools

There's also some other miscellaneous things mentioned including the gophp7-ext project trying to get as many extensions PHP 7 compatible and some sources for more "live" help for your questions.
