Error on serialize of ArrayObject
[2012-07-27 11:04 UTC] t dot weber at interexa dot de
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));

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[2012-08-05 12:56 UTC] lior dot k at zend dot com
