If the number of rows is greater than PHP_INT_MAX, the number will be returned as a string.

If the number of affected rows is greater than maximum PHP int value, the number of affected rows will be returned as a string value.

These stubs are automatically extracted, your changes would be overwritten immediately. You need to fix it in php-src, preferably in an earliest branch as possible - PHP-8.0.

Meanwhile, you can also report this problem in phpstan/phpstan, it might have another solution.

Yeah, these can be just fixed in resources/functionMap.php in phpstan-src.
