Subject: bug when using foreach with references?
From: richardkmiller@gmail.com (Richard K Miller)

Is this a bug in PHP?

<?php
$items = array('apple', 'banana', 'carrot');
print_r($items);
foreach ($items as &$item) { }
print_r($items);
foreach ($items as $item) { }
print_r($items);
?>

// Output:
Array
(
      [0] => apple
      [1] => banana
      [2] => carrot
)
Array
(
      [0] => apple
      [1] => banana
      [2] => carrot
)
Array
(
      [0] => apple
      [1] => banana
      [2] => banana
)

Two bananas in the last set?! Not what I expected.
