Not exactly sure, but I mean to remember that this caused some issues in the past.

Wow, thanks, that was fast. However, there is apparently a cron schedule in place for running CI; not sure if that's reasonable. Anyway, I'll try to keep an eye on this.

Okay, CI is running now; let's see how this goes.

Due to fail fast behavior, I'm not 100% sure, but at least on Windows tests/007.phpt fails with PHP 8.3:

--
         int(5)
       }
       ["bar"]=>
016-   string(3) "bar"
016+   NULL
     }
     array(2) {
       ["vars"]=>
--

I suggest to test with PHP 8.0, 8.1 and 8.2 for now.

I'd still keep the tests for PHP-8.0 (also for Windows below); there are likely users still on this PHP version, and it may even still be supported by some distros.

Thank you again! I have applied this via 7b70bbf.
