从数组php codeigniter创建一个对象用于登录系统

Question

i have a simple question, i'm creating a simple login system, and i want to assign user info into model class after success login,

example model

class user extends CI_Model {
    public $id=FALSE,$name,$role;

    public function __construct(){
        parent::__construct();

    //load user information
        if($this->session->userdata('user')){
            $u=$this->session->userdata('user');
            $this->id=$u->id;
            $this->role=$u->role;
            $this->name=$u->name;
        }

    }
    function login(){......}

but this just dont look right to me !! its ugly and not dry..

so should i use magic _set,_get ? or can i do something like $this=$this->session->userdata('user');

objective for me is since this model is on my Autoload, i want to be able to get user info from any other model/controller using simple $id=$user->id Or if($user->id)echo"hello".$user->name;

now if i do.

    private $data;

    public function __construct(){
        parent::__construct();
        $this->data = (object) $this->session->userdata('user');
    }
    public function __get($name) {
    if(isset($this->data->$name)){
        return $this->data->$name;
        }
    }

this will create an error "Call to a member function userdata() on a non-object"

i thinks thats because __get capture the $this->session ! so how can i fix this ?!
