Description:
------------
I don't expect the $total in the second foreach to still be a reference to the last item from the previous foreach.



Reproduce code:
---------------
<?php
  $totals = array(array('class' => 'Foo', 'value' => '1'),
                  array('class' => 'Test', 'value' => '2'),
                  array('class' => 'Bar', 'value' => '3'));

   foreach ($totals as &$total) {
   switch ($total['class']) {
     case 'Test':
        $total['value'] *= 2;
        break;
      default:
        break;
    }
  }

  foreach ($totals as $total) {
    echo $total['class'] . ' : ' . $total['value'] . "\n";
  }
?>


Expected result:
----------------
Foo : 1
Test : 4
Bar : 3


Actual result:
--------------
Foo : 1
Test : 4
Test : 4
