Bug description: iterating through an array plus creating a refererence to the
current element
Description:
------------
When I iterate through an array with "for" and create a reference to the
current element inside the for, then the last element of the array will be
a reference to the previous element.
If I unset the reference variable at the end of every cycle, then it works
fine.
Reproduce code:
---------------
<?php
$list = array(
array('id' => 1),
array('id' => 2)
);
for($i = 0; $i < count($list); $i++) {
$item = &$list[$i];
$item['someValue'] = 'x';
}
foreach($list as $item)
{
var_dump($item);
}
Expected result:
----------------
array(2) {
["id"]=>
int(1)
["someValue"]=>
string(1) "x"
}
array(2) {
["id"]=>
int(2)
["someValue"]=>
string(1) "x"
}
Actual result:
--------------
array(2) {
["id"]=>
int(1)
["someValue"]=>
string(1) "x"
}
array(2) {
["id"]=>
int(1)
["someValue"]=>
string(1) "x"
}
(Please note the second elements id, which is 1 instead of 2)
