Bug description: array_clone - would also clone referenced objects
Description:
------------
When you pass an array of objects to a function (not by reference) and you
modfiy one of the objects in the array, the main array (the referenced
objects) will be modified. This wasn't a problem until objects got passed
by reference by default.
Reproduce code:
---------------
$class A
{
}
$a = new A();
$a->x = 10;
$arr = array($a);
function foo($arr)
{
$arr[0]->x = 1;
}
foo($arr);
print_r($arr);
Expected result:
----------------
the expected result would be 10
Actual result:
--------------
since the array is internally using references for the stored objects the
result will be 1.
to fix this I wrote a function that clones the array properly and I'm
calling the function like this:
foo(array_clone($arr));
