It’s been a while since we bumped the minimum PHP version of WooCommerce to 7.0, and it is about time for a new bump. Starting with version 6.5, scheduled for release in May 2022, WooCommerce will require PHP 7.2 or newer to work.
Why this change?
The PHP ecosystem is evolving rapidly. At the time of writing this, the only actively maintained versions of PHP are 8.0 and 8.1; PHP 7.4 entered “security fixes only” mode and PHP 7.3 went unsupported as of December 2021. WordPress recommends at least PHP 7.4 for performance and security reasons, and these reasons are even more important on an e-commerce site.
