Description:
------------
foreach mechanism changed. foreach returns now the array not the key. This changed from 4.3.9 to 4.3.10


5.0.x retuns too as $key the sub arrays

Reproduce code:
---------------
<pre>
<?php
$demo_array = array('one', 'two', 'three');

print_r(array_keys($demo_array));
echo "\n\n";
foreach(array_keys($demo_array) as $key)
{
    echo $key."<br>";
}

?>

Expected result:
----------------
Array
(
    [0] => 0
    [1] => 1
    [2] => 2
)


0
1
2

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