I disagree. Having a child hold a reference to it's parent (in
composition of course) is a very common approach in object-oriented
programming. I don't think you have any problem with readability by
doing that and I don't think there's anything wrong with it at all.

But in this case it appears that A has B and B has A.
I would be alright if it was just A has B.
The circular part is where I think you get into trouble especially
with readability, and understandable code.

This is the composition vs. inheritance debate, right?
In inheritance, B is a descendant of A. With composition, A has a B.

This just seems like a really bad idea to me.
You also mentioned that there is a parent class, but I dont see the
extends keyword.
<?php
Class A {
var $msg = 'Why hello there my old friend';
function __construct() {
}
}
Class B extends A {
function __construct() {
}
}
$b = new B();
echo $b->msg;
