Thanks Curt.
This solution works indeed. BUT, there's one but. Isn't there a way to not
have to tell PHP that I want the return of $this->AddFoo() as a reference?
In the actual code I want to worry as little as possible about specific
things like this. Isn't it a little strange that you have to both let php
know it's returning a reference as well as let it know that it's expecting a
reference as return value?

Need to let php know this is returning a reference:
function &AddFoo() {
> 21 $Ref = &$this->Foos[];
> 22 $Ref = new Foo();
> 23 return $Ref;
I'm surprized this even works, its kind of confusing, i'd rather do
something like:
$foo = new Foo();
$this->Foos[] = &$foo;
return $foo;
> 26
> 27 $Bar = new Bar();
> 28 $Foo = $Bar->AddFoo();
And then let php know you want this as a reference:
$Foo = &$Bar->AddFoo(); <-- don't forghet the $ sign
