Description:
------------
I'm not sure if it's the right behavior, but seems that PHP doing it wrong, see the test script.

Test script:
---------------
$v = array();
$data = array('v1' => '0');
foreach($data as $k => &$v)
	;

foreach(array('v2' => '1') as $k => $v)
	;

var_dump($data);



Expected result:
----------------
array(1) {
  ["v1"]=>
  &string(1) "0"
}


Actual result:
--------------
array(1) {
  ["v1"]=>
  &string(1) "1"
}
