Absolutely, there will be a version 2.3.2 with corrections.
Thanks for your report. I have PHP 8.1.2 on Ubuntu but for some reason it didn't show this warning even with error_reporting(E_ALL), display_errors and track_errors enabled.
Anyway, I know what causes this, and I have fixed if for PmWiki 2.3.2, due in a few days.
This precise warning is indeed caused by a change in PHP where previously it treated undefined variables or null as an empty string, now it complains that these are undefined. The "@" before the variable that previously suppressed the warnings is no longer enough.
The fix I use is to wrap the possibly undefined variable with strval(), it makes it behave like it did before.
You can get the pre-release, or even only the files that changed since 2.3.1, from the top of the page Changelog:

Today I got a number of deprecated error messages in my pmwiki after setting up php to version 8.1.2 on arch linux. There seem to be new warnings in case of unset parameters to preg_repalce, strlen or strncmp. That happens for examplin pmwiki.php: Passing null to parameter #3 ($subject) of type array|string is deprecated in pmwiki.php on line 75 and also in some skin/cookbook scripts. Will there be a Version 2.3.2 with corrections?
