Summary: Error on serialize of ArrayObject
Status: Open
Type: Bug
Package: SPL related
Operating System: Cent OS
PHP Version: 5.3.15

The problem is that the unserialize of ArrayIterator (and also maybe ArrayObject or other SPL
classes) can not dereference object references.
A simpler Testcase:
<?php
$x = new ArrayObject();
$t = array($x, $x->getIterator());
$s = serialize($t);
$e = unserialize($s);
Fatal error: Uncaught exception 'UnexpectedValueException' with message 'Error at
offset 13 of 26 bytes' in /tmp/test2.php:5
Stack trace:
#0 [internal function]: ArrayIterator->unserialize('x:i:16777216;r:...')
#1 /tmp/test2.php(5): unserialize('a:2:{i:0;C:11:"...')
#2 {main}
thrown in /tmp/test2.php on line 5
If the order in the array is reversed it works, as now the ArrayObject is only a reference in the
array.
Same behaviour with PHP 5.4.5

Description:
------------
Serialize and direct unserialize of Objects does not work if return value of
ArrayObject::getIterator is contained in parent class (see Test script)
Test script:
---------------
class ObjA
{
private $_varA;
public function __construct(Iterator $source)
{
$this->_varA = $source;
}
}
class ObjB extends ObjA
{
private $_varB;
public function __construct(ArrayObject $keys)
{
$this->_varB = $keys;
parent::__construct($keys->getIterator());
}
}
$obj = new ObjB(new ArrayObject());
unserialize(serialize($obj));
