Yes. 1.31 is EOL, this is why we upgraded to 1.35.4. Precondition for MW 1.35 is PHP 7.3+, so additionally we upgraded to PHP 7.4.24. Whilst we *never* had a similar warning with 1.31.15 and PHP 7.2.24, *now* we have a PHP warning using the script with MW 1.35.4 and PHP 7.4.24.
So maybe the issue may have been fixed in 1.32, but surely it is *not* fixed in 1.35.4. Hope the description is clear now?
Closing the request without having understood it is, let us say, a little bit impolite.

Line 242 of ExtParser.php in 1.35 https://github.com/wikimedia/mediawiki-extensions-ParserFunctions/blob/REL1_35/includes/ExprParser.php#L242 is

The error message you're quoting seems to be still as it would be on the 1.31 branch - https://github.com/wikimedia/mediawiki-extensions-ParserFunctions/blob/REL1_31/includes/ExprParser.php#L242
break;
It was fixed in https://github.com/wikimedia/mediawiki-extensions-ParserFunctions/commit/d258457e018b which landed in 1.32, and is definitely part of 1.35.
It looks like you've not updated the ParserFunctions extension when you've updated MediaWiki core et al, if line 242 is still giving you an error about a break statement.
You are perfectly right. I beg your pardon! The test and live installations are correct but I mixed up the different wiki paths, and so I "managed" to call the old 1.31 script out of the MW 1.35/PHP7.4 environment. I am to blame, no one else. My request was total bs.
