overwrite private class members in php5?

[Norbert Wenzel <mail@xxxxxxxxxxxx>]

Hi, I've done something like this:

class MyClass {

  private $var;

  function __construct($value) {
    $this->var = $value;
  }

  public function printVar() {
    echo($this->var);
  }

}

$object = new MyClass('1');
$object->printVar(); // prints 1
$object->var = 3; // Fatal Error as expected
$object->$var = 2; // no error msg
$object->printVar(); // prints 2

Hows that possible or what's the difference between
 $object->var   and
 $object->$var ?

thanks in advance for your help!
Norbert
