Description:
------------
when doing another unserialize that creates objects in an
Serializable::unserialize implementation things break, the 'parent' isn't
unserialized correctly.
ok: PHP 5.3.3-7+squeeze14
ok: PHP 5.3.10-1ubuntu3.6
fail: PHP 5.4.4-14+deb7u2
fail: PHP 5.5.3
See phpt test script:
http://paste.kde.org/p83ce39d0/
Test script:
---------------
class Bar {}
class Foo implements Serializable {
public $test;
public function __construct($test) { $this->test = $test; }
public function serialize()
{
return $this->test;
}
public function unserialize($serialized)
{
//the following line causes problems
unserialize('O:3:"Bar":1:{s:4:"bar1";O:3:"Bar":0:{}}');
$this->test = $serialized;
}
}
$foo1 = new Foo('foo1');
$foo2 = new Foo('foo2');
$foo3 = new Foo('foo3');
$ar = array(
array(
'instance' => $foo1,
),
array(
'instance' => $foo2,
),
array(
'instance' => $foo3,
'parent' => $foo2
)
);
$ar = serialize($ar);
$ar = unserialize($ar);
print_r($ar);
Expected result:
----------------
[parent] => Foo Object ( [test] => foo2 ) )
Actual result:
--------------
[parent] => foo2
