There is a little mistake in a the code above, here it goes:

<? class a{
  var $temp;
  var $p_b;
  var $p_c;
  function a(){
    $this->p_b=new b(&$this);
    $this->p_c=new c(&$this);
  }

  function do_all(){
    $this->p_c->give_val();
    $this->p_b->show_val_c();
    echo " a: ".$this->p_c->something;
  }
}

class b{
  var $root;
  function b($root){
    $this->root=&$root;
  }
  function show_val_c(){
    echo " b: ".$this->root->p_c->something;
}
}

class c{
  var $root;
  var $something;
  function b($root){
    $this->root=&$root;
  }
  function give_val(){
    $this->something="something";
}
}

$r=new a;
$r->do_all();  ?>

Okay, you're right here, my mistake. But there is a bug anyway, I'll
show it on little bigger example:

<? class a{
  var $temp;
  var $p_a;
  var $p_b;
  function a(){
    $this->p_b=new b(&$this);
    $this->p_c=new c(&$this);
  }

  function do_all(){
    $this->p_c->give_val();
    $this->p_b->show_val_c();
    echo " a: ".$this->p_c->something;
  }
}

class b{
  var $root;
  function b($root){
    $this->root=&$root;
  }
  function show_val_c(){
    echo " b: ".$this->root->p_c->something;
}
}

class c{
  var $root;
  var $something;
  function b($root){
    $this->root=&$root;
  }
  function give_val(){
    $this->something="something";
}
}

$r=new a;
$r->do_all();  ?>

Obviously, we want to see here "b: something b: something", but all we
get is "b: a: something"

Change this:
 $this->root=$root;
To:
 $this->root =& $root;

and it'll work.

Description:
------------
You have two classes, one initialized in another's contructor. After
initializing the "child" class in "mother" constructor, all new values
assigned to variables in mother are not visible in pointed classes.

Reproduce code:
---------------
<? class a{
  var $temp;
  var $pointer;
  function a(){
    $this->temp=10;
    $this->pointer=new b(&$this);
    $this->temp=20;
    echo " A: ".$this->temp;
  }
}
class b{
  var $root;
  function b($root){
    $this->root=$root;
  }
  function show_val(){ 
    echo " B: ".$this->root->temp;
}
}
$r=new a;
$r->pointer->show_val();  ?>

Expected result:
----------------
A: 20 B: 20

Actual result:
--------------
A: 20 B: 10
