        "exp_month" => "12",
        "exp_year" =>  "19",

    )
);

$create = CreateToken::create($params);
CreateToken::prettyPrint($create);

if ($create["code"] == 200) {
    $get = CreateToken::get($create["response"]->id);
    CreateToken::prettyPrint($get);
}

class CreateToken {
    private static $key = "sk_test_...................";

    static function create($params)
    {
        $url = "https://api.stripe.com/v1/tokens";

        $headers[] = "Authorization: Bearer " . self::$key;
        $headers[] = "Content-Type: application/x-www-form-urlencoded";

        return makeCurlCall($url, "POST", null, $params, $headers);
    }

    static function get($id)
    {
        $url = "https://api.stripe.com/v1/tokens/$id";

        $headers[] = "Authorization: Bearer " . self::$key;
        $headers[] = "Content-Type: application/x-www-form-urlencoded";

        return makeCurlCall($url, "GET", null, null, $headers);
    }

    static function prettyPrint($data)
