Question

So like a function like this declare(strict_types=1); myfunc(): ?Array {

... database logics ...
if(!empty($db_results)) {
return $db_results;
}
}

does not require neither return []; nor return NULL; right?

What kind of syntax is this? ?Array $results It ...

sorry, fixed I was confusing with named parameters, return type declarations don't require a named value

This asserts that return value should be either null or array. In this case, if that condition isn't satisfied, then nothing is returned and it is an error. You should add return null; after that if statement to comply with defined return type.
