Happens to me on 5.0.3 as well.
Shorter code:
<?php
class A {
public function __set($key, $val) {
$this->data[$key] = $val;
}
}
$A = new A();
$A->foo['bar'] = 'oink';
$A->foo['bar1'] = 'oink1';
var_dump($undefined);
$undefined[] = 'blah';
var_dump($undefined);
?>
Outputs:
NULL
array(2) {
["bar1"]=>
string(5) "oink1"
[0]=>
string(4) "blah"
}

Description:
------------
The __set and __get don't seem to handle arrays correctly. What's even
worse, is it adds data to memory which is allocated at a later time
($boz gets foo2 and foo3 of $myObj). The code example speaks for
itself.
Reproduce code:
---------------
<?
class buggy {
private $data;
function __set($key, $val) {
$this->data[$key] = $val;
}
function __get($key) {
return $this->data[$key];
}
}
$myObj = new buggy();
$myObj->somevar['foo1'] = 'bar1';
$myObj->somevar['foo2'] = 'bar2';
$myObj->somevar['foo3'] = 'bar3';
$boz[] = 'blah';
print_r($boz);
?>
Expected result:
----------------
Array
(
[0] => blah
)
Actual result:
--------------
Array
(
[foo2] => bar2
[foo3] => bar3
[0] => blah
)
