<?php

    //1.创建cookie
    //创建cookie,如下设置，cookie的过期时间为会话结束时
    setcookie("name","gaoxiong");
    //创建一个包括过期时间的cookie
    setcookie("age",24,time()+(7*24*60*60));

    //设置cookie，获取cookie会慢一拍

    //2.读取cookie
    if (isset($_COOKIE[‘name‘])) {
        echo $_COOKIE[‘name‘];
    };

    //3.删除cookie
    setcookie("name",‘‘);
    setcookie("name","gaoxiong",time()-1);
