[PHP-DEV] Object reference

[Andrew Sitnikov]

Hello php-dev,

PHP4.3.0RC1

Source
----------------------------
<?
    $globalref_foo = array();
    $globalref_bar = null;

        class Foo {
                function Foo()
                {
                        global $globalref_foo;
                        $globalref_foo[] = &$this;
                }
        }

        class Bar {
                function Bar()
                {
                        global $globalref_bar;
                        $globalref_bar = &$this;
                }
        }

        $o1 = &new Foo();
        $o2 = &new Bar();

        var_dump($globalref_foo);
        var_dump($globalref_bar);
        var_dump($o1);
        var_dump($o2);
?>

Output:
----------------------------
array(1) {
  [0]=>
  &object(foo)(0) {
  }
}
NULL
object(foo)(0) {
}
object(bar)(0) {
}

Question:
----------------------------
 Why $globalref_bar===NULL  after  $o2 = &new Bar(); ?


Why
