Ok, the third line of that function is really weird. You're returning the
object anyway, so why would you want to return a property of the object? It
breaks encapsulation.
To return more than one item... have you considered simply returning an
array?
function f()
{
return (array (7, 5));
}
list ($a, $b) = f();
I can't really see a benefit to passing in $P1 and $P2 at all, let alone by
reference... maybe you could go into more detail about what you're trying to
do? Why do you need to return a reference to the object, rather than the
object itself?
