Restart nginx and php in order for the changes to take effect.
systemctl restart nginx && systemctl restart php8.2-fpm

The above assumes the user has php8.2-fpm. I even did fresh update today, and php doesn't auto update, so I'm still on 7.4
I had to find what version I had in order to update it.
So I suggest basically adding a few lines to find what version you have:

ps -ef | grep php-fpm -> Should output a php-[version]fpm
Or just php --version
And then restart it, e.g. in my case being 7.4 systemctl restart php7.4-fpm

While a command for determining your system's php version is useful, the submission guidelines on the README state the the guides should be made for the most recent stable version of Debian. As of writing this, php 8.2 is the current version in Debian Stable. So, is it a good idea to recommend an older version of php?

The DokuWiki documentation also recommends php 8, as 7.4 is EOL. Although it can run on php 7.4.
