Question: Is Cops compatible with php 8 ?

Answer: NO, not with the original code from https://github.com/seblucas/cops

However (YES) if you are willing to dive into the code and edit 1 line. Then COPS should work with PHP 8 (never tried with PHP 8.2).
Reference: https://github.com/seblucas/cops/issues/492

How:
1 - open file ../cops/vendor/seblucas/dot-php/doT.php
2 - change line 94

return @create_function ('$it', $func);

3 - to

return @function ($it) use ($func) {
        return eval($func);
        };

I did it like this:

        // For PHP 8 replace this line 
        //return create_function ('$it', $func);
        // with
        return function ($it) use ($func) {
        return eval($func);
        };
        // end replace

Please report back if it works for you.
