Description:
------------
Acessing class property (which is an array) using a variable makes it read only (can not add a new element)
See code if you don't understand what I mean.
$this->$nameOfArray[$key] = $value;

Using PHP4 style, haven't tried it in PHP5 class coding style. 

I'm under mac os, using php 5.1.6, installed by following this: http://www.entropy.ch/software/macosx/php/


Reproduce code:
---------------
class test {
  var $arrWhatever;
  function test() {
    $this->arrWhatever = array();
  }
  function set($where,$who, $what) {
     $this->$where[$who] = $what;
  }
  function set2($where,$who,$what) {
     $arrTmp =& $this->$where;
     $arrTmp[$who] = $what;
  }
}

$obj = new test();

$obj->set('arrWhatever','key','value');
print_r($obj->arrWhatever);

$obj->set2('arrWhatever','key','value');
print_r($obj->arrWhatever);


Expected result:
----------------
Array
(
    [key] => value
)
Array
(
    [key] => value
)

Actual result:
--------------
Array
(
)
Array
(
    [key] => value
)
