MongoDB object mapping (PHP)

Intoduction problem:

What is the best practice to build my class T object, when I receive it from a MongoCursor::getNext()? As far as it goes, getNext() function of a MongoCursor returns with an array. I wish to use the result from that point as an object of type T.

Should I write my own constructor for type T, that accepts an array? Is there any generic solution to this, for example when type T extends G, and G does the job as a regular way, recursively (for nested documents).

I'm new to MongoDB, and I'd like to build my own generic mapper with a nice interface.

Bounty:

• Which are the possible approaches, patterns and which would fit the concept of MongoDB the most from the view of PHP.
