PHP Bug Type:     Arrays related
Bug description:  foreach not manipulating last element when passed by reference

Description:
------------
This was reported in 2006 in the foreach user comment
http://uk.php.net/manual/en/control-structures.foreach.php#60806, but using
php5 using references in a foreach loop, manipulating the last element in
an array seems to have no effect, the reference is referred to as $v.

Reproduce code:
---------------
// fails to work as expected
$ar = array(1,2,3,4);

foreach ($ar as &$v){
    $v *= 2;
}
foreach($ar as $v){
    echo $v . '<br>';
}

// works correctly
$ar = array(1,2,3,4);

foreach ($ar as &$o){
    $o *= 2;
}
foreach($ar as $o){
    echo $o . '<br>';
}

Expected result:
----------------
2
4
6
8

Actual result:
--------------
2
4
6
6
