Bug description: ArrayIterator does not clone itself when referencing itself
Description:
------------
In test file array_022.phpt we see the clone being changed but this does
not change original, If you clone an ArrayIterator you also clone its
reference.
If you take such a self-wrapping ArrayIterator and clone it, the clone is
no longer self-wrapping: the clone wraps the original. HOWEVER, I *think*
the SPL_ARRAY_IS_SELF flag is being copied to the clone
Therefore, the clone starts to store/retrieve data from itself rather than
from its wrapped container - hence the difference.
Reproduce code:
---------------
<?php
class MyArrayIterator extends ArrayIterator
{
public function __construct()
{
parent::__construct($this);
$this['bar'] = 'baz';
}
}
$a = new MyArrayIterator;
$b = clone $a;
$b['baz'] = 'Foo';
var_dump($a);
var_dump($b);
?>
Expected result:
----------------
object(MyArrayIterator)#%d (2) {
["bar"]=>
string(3) "baz"
["baz"]=>
string(3) "Foo"
}
object(MyArrayIterator)#%d (2) {
["bar"]=>
string(3) "baz"
["baz"]=>
string(3) "Foo"
}
Actual result:
--------------
object(MyArrayIterator)#%d (1) {
["bar"]=>
string(3) "baz"
}
object(MyArrayIterator)#%d (2) {
["bar"]=>
string(3) "baz"
["baz"]=>
string(3) "Foo"
}
