On the model, in order to obtain the variables on the controller, the following code is used:

<code>public function __get($key)
{
    return get_instance()->$key;
}
</code>
Copy after login
Copy after login

But when loading the view, in order to obtain the variables on the controller, I chose to hang everything on the controller on the loader:

<code>$_ci_CI =& get_instance();
foreach (get_object_vars($_ci_CI) as $_ci_key => $_ci_var)
{
    if ( ! isset($this->$_ci_key))
    {
       $this->$_ci_key =& $_ci_CI->$_ci_key;
    }
}</code>
Copy after login
Copy after login

Why choose different methods for the same purpose? I think the method corresponding to the model is already very good
