Do you mean it "has" that type information because it's guaranteed by other logic? Or is $row already an object, in which case we're saying the same thing?

An object holding 20 people has no "date of birth" property, so how can it have a typehint for it? An object representing one row of the table can, and that's what most of the examples here are talking about.

I think maybe we're just talking cross-purposes - my example was a clumsy way of saying that *somewhere* the raw data coming back from the DBMS driver gets converted to an appropriate object.

The main point was that that conversion doesn't need some pool of empty objects to "fill up" with data, it just creates a new object for each row in the result set.
