For the millions of sites already running WordPress 5.0, 85% are using PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher 5.6 or above. We’ve also recently observed that showing notifications to encourage users to upgrade their PHP version has been very effective.

Depending upon feedback and effectiveness, we can follow up by bumping the required PHP version to 7 as early as December 2019.
