They're not pointers.
PHP is not C.
It happens to look C, but it's not.

It's an alias, not a pointer.

Style Tip:
Add var $A; var $B;
> function Main() {
>
> $this->A = new Sub_A($this);
I *think* you want &$this as the argument to do what you are trying to do...
>
> $this->B = new Sub_B($this);
>
> }
>
>
> }
>
> $test = new Main();
>
> $test->A->Modify('test');
>
> // this method should work, but doesnt (should return "test" instead of
> "untouched")
>
> echo $test->B->text."<br>";
>
> // parent isnt a pointer but a copy so absolute addressing works
>
> echo $test->A->parent->B->text."<br>";
>
> ?>
Bottom Line: It's not C. Don't expect it to work exactly like C.
