Here’s WordPress’s requirements: https://wordpress.org/about/requirements/
Basically PHP 7.4 or newer, MySQL 5.7 (or MariaDB 10.3) or newer, and a webserver that supports PHP and MySQL (Apache and Nginx are the most commonly used, but IIS and others do work fine).
WordPress 6.1.1 officially has “beta” support for PHP 8.x.
What this means is that WordPress will work with PHP 8.x, but you may see some PHP deprecation warnings or notices in your logs. But these are not fatal errors that should break WordPress or affect any functionality.
I personally run dozens of my own and client sites under PHP 8.2 and MariaDB 10.11 on Debian 11.6 (Bullseye) — and never had any issues.
But note that everything I’ve written above is just for the core WordPress software itself.
Any theme or plugin you run may have its own PHP version and PHP extension requirements and a few may break completely under PHP
8.x, though most should work fine. That’s unfortunately not something under the control of the WordPress project, so you’ll need to test each addon you use separately.
1. It looks like WordPress 6.1.1 will work with PHP 8 correct?
Yes, but see the comment above about themes and plugins.
2. Will PHP8 work with mySQL 8?
– What about PHP 7.2.7 ( I did see that in the windows platform installer)?
– However the latest version I see in the WPI is mySQL version 5.5 which is very old?
WordPress should work with MySQL 8. See this compatibility list: https://make.wordpress.org/hosting/handbook/compatibility/
Windows Platform Installer was last updated
February 14, 2013 and was officially declared abandoned by Microsoft last year. That’s over a decade of no update… and that would explain why you don’t see modern versions of PHP or MySQL included.
3. Will these configurations work with Windows Server 2012 or what configuration is best?
4. Will this configuration work with phpmyadmin?
What are you trying to accomplish here?
Are you setting up a local WordPress development server, or a production machine?
If you’re setting up a local development server, I”ll recommend you use an “all-in-one” WordPress appliance like Local (https://localwp.com).
