Description:
------------
When using the ++ operator on a property that is overloaded, the value inside the class is incremented *BEFORE* the call to the __set() method.

Reproduce code:
---------------
class overloaded
{
  private $values;
  function __construct()
  {
    $this->values = array('a' => 0);
  }
  function __set($name, $value)
  {
    print "<br>set $name = $value ($name was ".$this->values[$name].")";
    $this->values[$name] = $value;
  }
  function __get($name)
  {
    print "<br>get $name (returns ".$this->values[$name].")";
    return $this->values[$name];
  }
}
$test = new overloaded();
$test->a++;     // __get(), then __set()

Expected result:
----------------
get a (returns 0)
set a = 1 (a was 0)

Actual result:
--------------
get a (returns 0)
set a = 1 (a was 1)

Andi, is it supposed to work so or not?
I.e. is it a docu problem or a bug?

Fixed in CVS HEAD and PHP_5_0
