Classes (Explained inside)

Hi There as you can tell i am new to the community so firstly.

Hey all :D

Right to go into my problem. This is to write my own class base and core system. Read the code below to understand me further.

So all classes below will be seperate files. and will be included seperatly.

PHP Code:


			
class Base {
   public function load_class($class_name) { 
      include('core/'.$class_name.'.class.php');
      $this->$class_name = new $class_name();
      }
}

class Logging {
   public function error($msg) {
      print_r($msg);
      }

}

class Database extends Base {
   public function connect($coninfo) {
      $this->Logging->error($coninfo);
      }

}

include('core/Base.class.php');
$Base = new Base();

$Base->load_class('Logging');
$Base->load_class('Database');
$Base->Database->connect('info');

Ok it all works up untill i run the connect, when i try to use $this->Logging->error(); it produces a error

Fatal error: Call to a member function error() on a non-object

Hope i explained it ok :(. Basicly i need to be able to use the classes i setup in the Base obj.

Thank you so so much in advanced :D
