See the following script.

The depth of the print_r functions output is growing.

<?php

class A {
  var $x = 1;
  var $b = null;
  function A() {
  }
  function setB(&$b) {
    $this->b = &$b;
  }
}

class B {
  var $x = 2;
  var $a = null;
  function B() {
  }
  function setA(&$a) {
    $this->a = &$a;
  }
}

$a = new A();
$b = new B();
$a->setB($b);
$b->setA($a);
print_r($a);
$a->x = 3;
print_r($a);
$b->x = 4;
print_r($a);

?>
