Description:
------------
When I use foreach on an array the values are wrong. It's very critical.


Reproduce code:
---------------
<?
$a=array(5,10,15);
foreach($a as $b) var_dump($b);
?>

Expected result:
----------------
int(5)
int(10)
int(15)

Actual result:
--------------
array(2) {
  [0]=>
  int(5)
  [1]=>
  int(0)
}
array(2) {
  [0]=>
  int(10)
  [1]=>
  int(1)
}
array(2) {
  [0]=>
  int(15)
  [1]=>
  int(2)
}
