PHP Bug Type: Zend Engine 2 problem
Bug description: __clone is referencing object held inside a class instead of copying
Description:
------------
When a class holds an object of another class inside and the outside class
is cloned, the inside class seems to be referenced instead of cloned along
with the outside class
If you'll see below, you'll notice that the Test class is cloned properly,
the variable registered doesn't show up in $test but does in $test2
However, the array added to the list inside the Test2 class shows up in
both, when it should only be in $test2
New php5 snap as of 1/30/2004 apache2 module - mysql only extra extension
loaded
Reproduce code:
---------------
class Test
{
private $object;
private $list = array();
public function __construct()
{
$this->object = new Test2();
}
public function registerVar($var)
{
$this->list[] = $var;
$key = end(array_keys($this->list));
$this->object->setList($key);
return;
}
}
class Test2
{
public $list = array('globals' => array());
public function setList($id)
{
$id = (int) $id;
$this->list[$id] = array();
return;
}
}
$test = new test();
$test2 = $test->__clone();
$test2->registerVar('hello');
print_r($test);
print_r($test2);
Expected result:
----------------
Test Object
(
[object:private] => Test2 Object
(
[list] => Array
(
[globals] => Array
(
)
)
)
[list:private] => Array
(
)
)
Test Object
(
[object:private] => Test2 Object
(
[list] => Array
(
[globals] => Array
(
)
[0] => Array
(
)
)
)
[list:private] => Array
(
[0] => hello
)
)
Actual result:
--------------
Test Object
(
[object:private] => Test2 Object
(
[list] => Array
(
[globals] => Array
(
)
[0] => Array
(
)
)
)
[list:private] => Array
(
)
)
Test Object
(
[object:private] => Test2 Object
(
[list] => Array
(
[globals] => Array
(
)
[0] => Array
(
)
)
)
[list:private] => Array
(
[0] => hello
)
)
