PHP is still one of the most popular languages used to build the web. The newest version, PHP 7.4, was released today — and Business and eCommerce plan customers can opt to start using it immediately.

WordPress.com sites run PHP 7.3 by default — it's still our recommended version, since it's been stress-tested across all of WordPress.com — but if you have a site on the Business or eCommerce plan and want to be on the leading technological edge, you can opt to switch to version 7.4 immediately.

Head to My Site > Manage > Hosting Configuration to find the new PHP Version Switcher:

Choose which version of PHP you want your site to run on, click the "Update PHP version" button, and voilà.

(Note: All sites with eCommerce plans can make the switch right now. Sites on the Business plan need to have either an active plugin or a custom theme to use the PHP Version Switcher.)

PHP's evolved with each version 7 release, and PHP 7.4 promises to have the strongest performance yet. It will eventually power all WordPress.com sites, but Business and eCommerce customers can take advantage of the update today!
