2，演示示例 demo.php

require 'Cookies.class.php';
$type = isset($_GET['type'])? strtolower($_GET['type']) : '';
if(!in_array($type, array('set','get','update','clear'))){
exit('type not exists');
}
$obj = new Cookies('member', 10); // obj
switch($type){
case 'set': // 设置

echo 'set cookies';
break;
case 'get': // 读取
$result = $obj->get('me');
