Bug description: Overloading bug
Description:
------------
Overloading results in unexpectable behaviour when using two arrays in
overloaded object.
Reproduce code:
---------------
// basic overloading usage
class Test {
private
$vars = array(),
$vars2 = array();
function __get($name)
{
return $this->vars[$name];
}
function __set($name, $value)
{
$this->vars[$name] = $value;
}
// initialize new variable
function add($name, $value)
{
$this->vars[$name] = $value;
// this second array is not used anymore - but it causes error
$this->vars2[$name] = $value;
}
}
$obj = new Test();
$obj->add('order', array(0, 1, 2));
// first test
$obj->order[2] = $obj->order[1];
print_r($obj);
// second test
$obj->order[0] = 99;
print_r($obj);
Expected result:
----------------
// first test
Test Object
(
[vars:private] => Array
(
[order] => Array
(
[0] => 0
[1] => 1
[2] => 1
)
)
[vars2:private] => Array
(
[order] => Array
(
[0] => 0
[1] => 1
[2] => 2
)
)
// second test
Test Object
(
[vars:private] => Array
(
[order] => Array
(
[0] => 99
[1] => 1
[2] => 1
)
)
[vars2:private] => Array
(
[order] => Array
(
[0] => 0
[1] => 1
[2] => 2
)
)
Actual result:
--------------
// first test
Test Object
(
[vars:private] => Array
(
[order] => Array
(
[0] => 0
[1] => 1
[2] => 2
)
)
[vars2:private] => Array
(
[order] => Array
(
[0] => 0
[1] => 1
[2] => 2
)
)
)
// second test
Test Object
(
[vars:private] => Array
(
[order] => Array
(
[0] => 99
[1] => 1
[2] => 2
)
)
[vars2:private] => Array
(
[order] => Array
(
[0] => 99
[1] => 1
[2] => 2
)
)
)
