Support type infering of getArrayResult when selecting specific fields

[janedbal]

Is there a possibility to support array hydration type infering when field list is selected? I can see it actually works, but is not supported for getArrayResult nor ->getResult(AbstractQuery::HYDRATE_ARRAY) even though the behaviour in doctrine is equal.

I can send failing tests if needed.

Hi @janedbal

Unfortunately, supporting more than one hydration mode is challenging for the reasons detailed here. So for now phpstan-doctrine supports only the HYDRATE_OBJECT mode.

As you pointed out, selecting individual fields is supported in HYDRATE_OBJECT mode, so in some cases it may be possible to use getResult() instead of getArrayResult():

$query = $em->createQuery('
    SELECT e.foo, e.bar FROM Entity e
');

$query->getResult(); // array<array{foo: string, bar: string}>

I see, thanks for quick response.

Sidenote: Sad to hear that using (semantically) improper HYDRATE_OBJECT in those cases (it cannot hydrate objects when custom fields are selected) is the only working approach, but I think the benefits of type-inference is huge enough to convert our codebase to use that and write some phpstan rule to ensure that it in future.
