Access function from model class or controller class from helper file with Codeigniter

I know it is not a good experience. But just I want to know it is possible to access a function from model or controller class from a helper file 开发者_如何学Goin codeigniter.

cant you use something like this i believe.

$Helper =& load_class('Helper'); //Load the (Helper Loader) $this->load->helper becomes $helper
$Class = $Helper('Name of class');

But i do not see why you should do this

Can't you just create an extra model class like

class DBFile
{
   ...
}

then create your Model

class Model_SomeName extends DBFile
{
  /*So no this uses DBFile instead of CI_Database or w.e it is*/
}

Yes, that is possible, you will have to load the helper class first like this:

$this->load->helper('name of helper class');
