Question about using session on OOP

[eldan88]

Hey,

 

 I am creating a session class for one of my ecommerce application. Below is the class I have created. I was wondering how would I go about creating a message for the session being expierd and a message if the session was not found? Also does this class look correct? Thanks

class Session {

public $mycart; 
public $store_name; 
public $discount_session; 


function __construct() {
	session_start(); 
	$this->store_name();

}

function store_name() {
	if(isset($_SESSION['store_name'])) {
	$this->store_name = $_SESSION['store_name'];
	}
 
	
}

function my_cart() {
	if(isset($_SESSION['my_cart'])) {
	$this->mycart = $_SESSION['store_name'];
	}

}


function discount_session() {
	if(isset($_SESSION['discount_session'])) {
	$this->discount_session = $_SESSION['discount_session'];
	}

}
	
	
	}
	
$session = new Session;
