PHP version: 5.2.12
PHP Bug Type: Class/Object related
Bug description: array of objects: copying passes reference instead of copy
Description:
------------
PHP 5 does not copy object from array[ndx] to a new array entry, instead
it seems to pass a reference to the original.
Reproduce code:
---------------
function fetchData()
{
// return array of objects
}
$arr = fetchData();
$newNdx = count($arr);
$arr[$newNdx] = $arr[0]; // create copy of first object
$arr[$newNdx]->description = 'Change description';
Expected result:
----------------
The result is that $arr[0]->description will also have changed when we
modified $arr[$newNdx]->description, therefor not copying, but more like
creating a reference to the original.
This happens only in PHP 5, not 4.
