echo "COOKIE 为: ".$_COOKIE["PHPSESSID"];".$_COOKIE["PHPSESSID"];session的本质和cookie是差不多的，保存着http状态信息。简单来说、Session是一次浏览器和服务器的交互的会话，会话是啥呢？就是我问候你好吗？你回答说很好。就是一次会话，那么对话完成后，这次会话相当于就结束了，但为什么会出现Session会话呢？因为我们用浏览器访问网站用的是http协议，http协议是一种无状态的协议，就是说它不会储存任何东西，每一次的请求都是没有关联的，无状态的协议好处就是快速；但它也有不方便的地方，比如说我们在login.php登录了，我们肯定希望在index.php中也是登录的状态，否则我们登录还有什么意义呢？但前面说到了http协议是无状态的协议，那访问两个页面就是发起两个http请求，他们俩之间是无关联的，所以无法单纯的在index.php中读取到它在login.php中已经登陆了的；为了解决这个问题，cookie就诞生了，cookie是把少量数据存在客户端，它在一个域名下是全局的，相当于php可以在这个域名下的任何页面读取cookie信息，那只要我们访问的两个页面在同一个域名下，那就可以通过cookie获取到登录信息了；但这里就存在安全问题了，因为cookie是存在于客户端的，那用户就是可见的，并且可以随意修改的；那如何又要安全，又可以全局读取信息呢？这时候Session就出现了，其实它的本质和cookie是一样的，只不过它是存在于服务器端的。<?php
