Classes, Constructors, References and Recursion

[Evert | Rooftop Solutions <evert@xxxxxxxxxxxxxxxxxxx>]

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
