Starting today, you may install PHP 8.1 Release Candidates by choosing "PHP 8.1 RC" while creating a new server. Or, you may install the release candidate on an existing server via the PHP tab on a server's management dashboard.
Some Forge features, PHP features, and PHP extensions may not work as expected when combined with PHP 8.1. In addition, once that PHP version becomes stable, you will need to fully uninstall and re-install PHP 8.1 via the PHP tab on a server's management dashboard.
If you don’t have a Forge account, now is a great time to sign up! Forge allows you to painlessly create and manage PHP servers which include MySQL, Redis, Memcached, database backups, and everything else you need to run robust, modern Laravel applications.
