Same issue as:
http://bugs.php.net/bug.php?id=31108

Upgrade Zend Optimizer and it fixes it.

I can also confirm this is an issue.

Description:
------------
The foreach($array as $key) construct returns an array for $key, instead of just the key. This
breaks many scripts that count on $key being a scalar (and well, the key).


Reproduce code:
---------------
$test = array(2, 3, 4, 5);

foreach($test as $key){
	print_r($key);
}

Expected result:
----------------
2345

Actual result:
--------------
Array
(
    [0] => 2
    [1] => 0
)
Array
(
    [0] => 3
    [1] => 1
)
Array
(
    [0] => 4
    [1] => 2
)
Array
(
    [0] => 5
    [1] => 3
)
