Description:
------------
I was trying to fill an array with objects by cloning the object as the argument in the function.

I read http://us2.php.net/manual/en/language.oop5.basic.php#language.oop5.basic.new
It mentions that passing the object to a function is a reference - but why doesn't cloning work, either?  I tried two different ways to pass a cloned object, but still got a referenced object rather than a cloned one.

Reproduce code:
---------------
class Foo {
  var $ar;
  function __construct() {
    $this->ar = array(0,0,0);
  }
}
//use clone keyword
$obj = new Foo();
$bar = array_fill(0,2,clone $obj);
print_r($bar);
$bar[1]->ar[0] = 1;
print_r($bar);

//a different way to clone
$obj = new Foo();
$bar = array_fill(0,2,$t = clone $obj);
print_r($bar);
$bar[0]->ar[0] = 1;
print_r($bar);

Expected result:
----------------
Array
(
    [0] => Foo Object
        (
            [ar] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                )
        )
    [1] => Foo Object
        (
            [ar] => Array
                (
                    [0] => 1
                    [1] => 0
                    [2] => 0
                )
        )
)

Actual result:
--------------
Array
(
    [0] => Foo Object
        (
            [ar] => Array
                (
                    [0] => 1
                    [1] => 0
                    [2] => 0
                )
        )
    [1] => Foo Object
        (
            [ar] => Array
                (
                    [0] => 1
                    [1] => 0
                    [2] => 0
                )
        )
)
