Description:
------------
foreach seems to increment the pointer used by current() once even if foreach 
loops multiple times. Seems to me that it should not increment it at all or 
increment it multiple times. Not once and that's it.

Test script:
---------------
<?php
$a = array(1, 2, 3, 4, 5);
foreach ($a as $key => $elem) {
    echo "$key = $elem"; echo ' = ';
    var_dump(current($a));
}
?>

Expected result:
----------------
0 = 1 = int(1)

1 = 2 = int(1)

2 = 3 = int(1)

3 = 4 = int(1)

4 = 5 = int(1)

Actual result:
--------------
0 = 1 = int(2)

1 = 2 = int(2)

2 = 3 = int(2)

3 = 4 = int(2)

4 = 5 = int(2)
