Bug description:problem with array, foreach and reference
Description:
------------
The code is very simple and speaks for itself.
Test script:
---------------
<?php
$data = array(array('name' => 'Lucas', 'surname' =>
'Barrena'));
foreach($data as &$row) {} #here, with reference
#unset($row); #this line, fix everything
$copy = $data;
print_r($copy);
#set, method A
$data = array(array('name' => 'Lcs'));
#method A-1: works
#without foreach
#method A-2: fails
foreach($data as $row) {}
#method B, fails
#$data[0]['name'] = 'Lcs';
#without foreach
print '<br>';
print_r($copy); #now copy it's different with methods fails
Expected result:
----------------
$copy should not be different.
