Description:
------------
After using foreach($arr as $k => &$v) to modify the $arr,
iterating again using the same variable $v causes the array to
be altered unexpectedly.
Adding an unset($v) between the two foreach loops, or using a
different variable on the second foreach loop works around the
problem.
Reproduce code:
---------------
<?
$arr = array(
'one' => 1,
'two' => 2,
'three' => 3,
);
foreach($arr as $k => &$v)
if($v == 1)
$v = 'meh';
print_r($arr);
foreach($arr as $k => $v)
;
print_r($arr);
Expected result:
----------------
The code above should not cause the $arr to be modified by
running the second foreach loop.
Actual result:
--------------
The code above outputs the following:
Array ( [one] => meh [two] => 2 [three] => 3 )
Array ( [one] => meh [two] => 2 [three] => 2 )
