How can I store object class into a session in PHP?

Question

How can I have an object class store into PHP session and then get it in my next page as variable. Could you help?

Here is my class.inc.php

class shop {

var $shoeType;
var $color;

    public function __construct() {

        $shoeTypeService = new ShoeTypeService();
        $shoe = $shoeTypeService->getAllShoes();
        $this->shoeType = $shoe[20];
    }
}

Once you instantiate the class you can assign it to the session (assuming it's started)

$_SESSION['SomeShop'] = new Shop();

or 

$Shop = new Shop();
//stuff
$_SESSION['SomeShop'] = $Shop;

Keep in mind that wherever you access that object you will need the Shop Class included.
