Fixes phpstan/phpstan#11883
It's largely a copy-paste of
ParameterCastableToStringRule
(#3132). I checked php-src and as far as I can tell this is the code that's used byarray_sum
/array_product
to convert objects to numbers. It seems to correspond toType::toNumber()
in PHPStan.It seems that resource worked before PHP 8.3, but I'd report it anyway, since I can't imagine a scenario where you'd want
array_sum
/array_product
