[PHP] Classes, Constructors, References and Recursion

[Evert | Rooftop Solutions]

Hi,
I have this piece of code:
 class test1 {
       var
               $data = 'hi',
               $node = false;
       function test1() {
               $this->node =& new test2($this);
       }
 }

 class test2 {
       var
               $data = 'yoyo',
               $root = false;
       function test2(&$root) {
               $this->root =& $root;
       }
 }
 $test =& new test1();
 echo('<pre>');
 print_r($test);
 echo('</pre>');
And it outputs:
test1 Object
(
   [data] => hi
   [node] => test2 Object
       (
           [data] => yoyo
           [root] => test1 Object
               (
                   [data] => hi
                   [node] =>  *RECURSION*
               )
       )
)
while it should output:
test1 Object
(
   [data] => hi
   [node] => test2 Object
       (
           [data] => yoyo
           [root] => *RECURSION*
       )
)
I know there are some difficulties using references in constructors, but 
I think this should be right..
I'm using PHP/4.3.11. Can anyone tell me what is wrong with this code or 
why PHP behaves this way?

regards,
Evert
