When you assign $a[] &= $object; not only is $a[$i] a reference to
$object, but it also works the other way around.
So in your next iteration, when you call $object = new Test(); you ARE
creating a new object, unfortuately this new object is overwriting
$object, which means it's also overwriting $a[$i-1]. Since the
original instance is no longer referenced, it gets destroyed and you're
left with one object.
To get your expected behavior put unset($object); after your assign it
to your array:
for($i=0;$i<10;$i++) {
$object = new Test();
$object->iterator=$i;
$a[]=&$object;
unset($object);
}
This will de-couple the reference link between $object and $a[$i].

i must agree rodolfo, this is correct for php5
but in php4 it is buggy

I've just ran your example and found that if you write a[]=$object
(without &), it runs flawlessly.

I've experienced something similar with 'clone' when the cloned
variable is used in mysqli_bind_result, as I said in bug #28870.

Description:
------------
If using "new" in a for-loop it seems that the same instance is re-used
all the time. This is not what is expected, because in terms of OOP the
new-operator schould create a new instance every time.
Tested with 4.3.3 and 5.0RC3
Reproduce code:
---------------
<?
class Test {
var $iterator;
}
$a=array();
for($i=0;$i<10;$i++) {
$object = new Test();
$object->iterator=$i;
$a[]=&$object;
}
foreach($a as $object) {
echo $object->iterator."<br>";
}
?>
Expected result:
----------------
Output should be:
0
1
2
3
4
5
6
7
8
9
Actual result:
--------------
Output actual is:
9
9
9
9
9
9
9
9
9
9
-> The same instance is reused all the time.
