green bean question on singleton php5

[julian <correojulian33-php@xxxxxxxx>]

Hi,

I am implementing this

class dbaccess{
  static $db=null;
  static $othervar=33;
	
  private  function dbaccess(){
    dbaccess::$db= new mysqli("localhost",USER,PASSWD,DB);
    if(mysqli_connect_errno()){
      echo "no way";
    }
  }
	
public static function GetDb(){
  if(dbaccess::$db==null){
  dbaccess::$db= new dbaccess();
  }
  return  dbaccess::$db;
	
  }
}


$db=dbaccess::GetDE();

$db->query(..................);

will fail...with Call to undefined method dbaccess::query()

apparently $db is of type dbaccess... and thus has not does not have 
query implemented....


any hhelp appreciated.....
