Question

Might be I am missing something obvious.
I have a native class with set and get method.

class DBStorage extends NativeClass{
  public function get($key);
  public function set($key,value);
}

I would like to use that most of the time, but, if I turn on the system DEBUG flag.
I would like the set and get methods to be overloaded with the following:

IF DEBUG IS ON{
    class DBStorage extends NativeClass{
      public function get($key){
         var_dump($key);
         parent::get($key);
      }
      public function set($key,$value){
         var_dump($key,$value);
         parent::set($key,$value);
      }
    }
}

NativeClass is written in C. It is an extension (phpredis, but it is not relevant).
How would I accomplish this?
I am on the 5.3 branch of PHP.

just to make sure…if debug is off, DBStorage will be:

 class DBStorage extends NativeClass{}

if debug is on, it will be:

class DBStorage extends NativeClass{
      public function get($key){
         var_dump($key);
         parent::get($key);
      }
      public function set($key,$value){
         var_dump($key,$value);
         parent::set($key,$value);
      }
    }

I do try to avoid the cluttring of IFs (there are dozens of functions in the real class)

public function get($key) {
       if (DEBUG) {
           var_dump($key);
       }
       return parent::get($key);
   }

something just came to me

class nodebug extends NativeClass{
  static public function create(){
        if(DEBUG) return new DebugNativeClass;
        return new self;
  }
}

class DebugNativeClass extends nodebug{
    public function set($key,$value){
       var_dump($key,$value);
       parent::set($key,$value);
    }

    public function get($key){
       var_dump($key);
       return parent::set($key);
    }

}
