php实现会员登陆注册页有html加Session和Cookie
发布时间:2022/8/18 17:27:00 来源: 纵横数据
用户注册信息,管理员核对信息审核通过后,可实现注册的用户名和密码的成功登陆,利用session和cookie获取用户信息并且不能跳过登录页面直接进入主页面
1.Session
存储在服务器
可以存储任何内容
有默认过期时间:大约15分钟
相对比较安全
用法:
1.必须在php页面开始写:session_start();开启session
2.写Session: $_SESSION["uid"]=$uid;
3.读取Session:$_SESSION["uid"];
2.Cookie
存储在客户端
只能存储字符串
默认没有过期时间
用法:
1.设置Cookie:setcookie("name","value");
2.取值:$_COOKIE["name"];
在php里面写
目的:
获取用户信息
不能跳过登陆页面
