Unless an addon, skin, recipe or local customization calls the functions 
PCCF(), Markup_e()/PPRA() with evaluated code, create_function(), 
PPRE(), or create a custom pagelist sort orders the old way, indeed the 
warning should be gone.

If I have missed such a call from the PmWiki core, I'll fix it 
immediately - more information on what steps you did will help me 
experience the warning myself and fix it.

If the PmWiki core does not raise a warning, see if the addons, skins, 
recipes you use have a more recent PHP7.2-compatible version. You can 
disable them all and re-enable them one after another to see which 
one(s) trigger the warning.

I recently rewrote the documentation about making addons work with PHP 
7.2 (and earlier), see the pages:

   http://www.pmwiki.org/wiki/PmWiki/Functions#PCCF
   http://www.pmwiki.org/wiki/PmWiki/Functions#PPRE
   http://www.pmwiki.org/wiki/PmWiki/CustomMarkup
   http://www.pmwiki.org/wiki/PmWiki/CustomPagelistSortOrder

If this is insufficient or appears too complex, I will offer assistance 
for updating recipes and skins for PHP 7.2.
