PHP Bug Type: Arrays related
Bug description: Incorrect array assignment
Description:
------------
If you keep reference to an element of the array before the copy operation
using = operator, you can still modify both the arrays using the reference
copied earlier.
The same doesn't happen if you keep the reference after the copy operation
and try to modify the variable using it.
Reproduce code:
---------------
<?php
$arr1 = array(1, 2);
$var = &$arr1[0];//Keeping the reference
$arr2 = $arr1;//Copy operation
$var = 10;//Will modify both the arrays, bad
print_r($arr1);
print_r($arr2);
?>
Expected result:
----------------
Array
(
[0] => 10
[1] => 2
)
Array
(
[0] => 1
[1] => 2
)
Actual result:
--------------
Array
(
[0] => 10
[1] => 2
)
Array
(
[0] => 10
[1] => 2
)
