Description:
------------
That code works:

public function __construct() {
$this->data = new stdClass();
}
public function & __get($property) {
if (isset($this->data->$property)) {
return $this->data->$property;
}
return null;
}
public function __set($property,$value) {
$this->data->$property = $value;
}
}
function chgTxt(& $txt) {
$txt = '-----';
}
$o = new A();
$o->int = 1;
$o->int++;
echo $o->int,'<br />';//result: 2 - reference in A::get() works fine
$o->txt = 'string';
chgTxt($o->txt);
