Note: it works fine for PHP 8+.

You can download PHAR from 0.25.1 to check it as well.

@theofidry probably you will have some time to give an advice, as I'm not sure I understand what is going on there.

I cna check atm but i would check if the polyfills are whitelisted the proper way. I think humbug/php-scoper#481 is the way to go for them

Looks like this won't be fixed, as a work around install via composer as development dependency. You can do this on the same project or in a different folder, by example:

mkdir -p tools/infection
composer require -d tools/infection --dev infection/infection
tools/infection/vendor/bin/infection ...

I was confused about the error message because the documentation still says it's support PHP 7.4: https://infection.github.io/guide/installation.html but the phar file only works with PHP 8, or?

PHP version	Infection version
7.4.0	>= 0.18

[maks-rafalko]

well, it should work on 7.4 for 0.26.x version. Isn't it the case?

Next Infection version (0.27.x) will work only on PHP 8+.

No it's not working with PHP 7.4, still the same error from Symfony\Polyfill\Php80\Php80

For what it's worth as soon as a PR is merged on AMP functions (which should be soon), I can do a release of Box which should fix (partially) support for up to 8.1.
