Ok, but this did work using PHP 5.1.6 so you can call this a
regression. If I understand this correctly the only way to work-around
this is using some code like the following:
$b = array();
$b[] = '1';
$b[] = '2';
$b[] = '3';
$obj->b = $b;
Or in a more realistic case where other methods assign something to the
object:
$b = $obj->b;
$b[] = '3';
$obj->b = $b;
Seems not very intuitive to me.

turn on error reporting and you will find the cause.
PHP Notice: Indirect modification of overloaded property Data::$b has
no effect.

Description:
------------
I've created a small class that implements the magic __set, __get and
__isset methods. Using PHP 5.1.6 I can assign an array to a "fake"
instance variable and then add elements to it. Doing the same using PHP
5.2.1 or 5.2.2 doesn't change the contents of the array.
I've tried returning a reference from the __get method (e.g. changes
the function definition to "function &__get($key, $value) ...", but this
doesn't work either (although PHP doesn't complain about it).
If this wasn't supposed to work with PHP 5.1.6 how should I then
implement this to get the desired behaviour? If this isn't possible at
all then that means __set/__get are far less usable then before.
Reproduce code:
---------------
class Data
{
private $m_data = array();
function __set($key, $value) { $this->m_data[$key] = $value; }
function __get($key) { return $this->m_data[$key]; }
function __isset($key) { return isset($this->m_data[$key]); }
function dump() { var_dump($this->m_data); }
}
$obj = new Data();
$obj->a = "a";
$obj->b = array();
$obj->b[] = '1';
$obj->b[] = '2';
$obj->b[] = '3';
$obj->dump();
Expected result:
----------------
array(2) {
["a"]=>
string(1) "a"
["b"]=>
array(3) {
[0]=>
string(1) "1"
[1]=>
string(1) "2"
[2]=>
string(1) "3"
}
}
Actual result:
--------------
array(2) {
["a"]=>
string(1) "a"
["b"]=>
array(0) {
}
}
