I'm using PHP Version 7.1.25 on my local machine.

Magento 2.3.x technology stack requirements

PHP 7.2 compatibility for the 2.3.0 release. Any backward-incompatibility issues will be resolved in this release, and all 3rd party libraries now support PHP 7.2. Fully tested 7.2 support will be delivered in following patch releases. If you are interested in participating in Magento Community projects we welcome your help! See our ZenHub board for a full list of outstanding issues.
