            $quantity = test_input($_POST["quantity"]);
            $bran = test_input($_POST["bran"]);
            $items[]=array($variety,$quantity,$bran,$rice_type);
            $json = json_encode($items);
            setcookie('cards', $json);
            print_r($items);
        }

        function delete()
        {
            setcookie( 'cards', "", time()-3600);
            header('location:cart.php');            
        }

        function cartlen()
        {

        }

    ?>

Error message is clear, isn't it? Inside a `Class` only functions are allowed, nothing else. — pavel, May 07 '15 at 06:50

You can not place the app logic inside your class like that. Classes have their rules.

If you are trying to call your codes when this class is initialized; you have to place them in the class constructor.

<?php

class CartUpdate
{

    /**
     * Initialize the Cart.
     * @return void
     */
    public function __construct() {

        if(isset($_COOKIE['cards'])) {
            $cookie = $_COOKIE['cards'];
            $cookie = stripslashes($cookie);
            $savedCardArray = json_decode($cookie, true);
            $variety=$savedCardArray['CART'][0];
            $quantity=$savedCardArray['CART'][1];
            $bran=$savedCardArray['CART'][2];
        }
        setcookie('total', $total);
    }

    }
    function add()
    {
        $variety = test_input($_POST["variety"]);  
        $rice_type = test_input($_POST["rice_type"]);
        $quantity = test_input($_POST["quantity"]);
        $bran = test_input($_POST["bran"]);
        $items[]=array($variety,$quantity,$bran,$rice_type);
        $json = json_encode($items);
        setcookie('cards', $json);
        print_r($items);
    }

    function delete()
    {
        setcookie( 'cards', "", time()-3600);
        header('location:cart.php');            
    }

    function cartlen()
    {

    }

?>
