Object Context Question in object->object->variable

[Sancar Saran <sancar.saran@xxxxxxxxxx>]

Hello list.

I'm trying to implement someting on OO way. 

I got 2 classes

class a {
  var $config = array();
  var $b = '';

  function  __construct {
   $this->b = new b($this->config);
 }

}

class b {
  var $config = array();
  function foo() {
    switch($this->config['bar']) {

   }
  }
}


some where in class a



and when I call 

$bar = new a();

$bar->b->foo();

I got 

Fatal error: Using $this when not in object context in

Could you givme some clue what is wrong ?


I'm using Ubuntu and PHP 5.2.0-8+etch13 

Regards

Sancar
