Just compare the output of print_r($arr) and foreach(...)...  !!!   Please, 
explain, or my understanding of the php is gonna ruin.
Thanx, Mark.

<?
 $as = array();
 $a10 = "10";
 $a20 = "20";

 $a = &$a10;
 $arr[] = &$a;
 $a = &$a20;
 $arr[] = &$a;

 print_r($arr);
 foreach($arr as $a)
 {
  echo $a;
 }
?>
