本文实例讲述了PHP实现的Cookies操作类及其用法,分享给大家供大家参考。具体分析如下:
一、功能:
1.保存,读取,更新,清除cookies数据。 2.可设置前缀。 3.强制超时控制。 4.cookies数据可以是字符串,数组,对象等。
二、用法:
Cookies.class.php类文件如下:
<?php
/** Cookies class 保存,读取,更新,清除cookies数据。可设置前缀。强制超时。数据可以是字符串,数组,对象等。
* Date: 2013-12-22
* Author: fdipzone
* Ver: 1.0
*
* Func:
* public set 设置cookie
* public get 读取cookie
* public update 更新cookie
* public clear 清除cookie
* public setPrefix 设置前缀
* public setExpire 设置过期时间
* private authcode 加密/解密
* private pack 将数据打包
* private unpack 将数据解包
* private getName 获取cookie name,增加prefix处理
