Thanks to nono303 on GitHub we can run this PHP extension and memcached on Windows! This is great for a dev environment to match a production unix server. I am using PHP 8.0 with this memcache extension on a Windows 10 box with a memcached server running on localhost and it is working great.
I can't post a link but the dll for this extension is at the repo: nono303/PHP-memcache-dll
And the actual memcached server for windows is at the repo: nono303/memcached
