With the upcoming release of the first stable version of PHP 7 Cal Evans has been posting a "7 Days of PHP 7" series, linking to information about the upcoming release, presentations, podcasts and more about this upcoming version. In this post to his site he gathers them all into one place with links to everything for easier consumption.
PHP 7 was originally supposed to be released today, November 12th, 2015. The Core developers weren’t comfortable releasing it just yet so they pushed the date back to November 26th, 2015. That’s fine, we all appreciate their diligence.
Still, I had already started my “7 Days of PHP 7” countdown when they made the announcement. Because the actual release date isn’t important to spreading the word about PHP 7, I decided to continue on with the countdown.
In his tweets he links to things like the PHP 7 migration manual, an article about PHP 7 performance and video tutorials on getting up and running with PHP 7. Check out the full post for more information on these and other useful PHP 7-related resources.
