首先是一个普通的登陆页面实现
登录页面login.php
<!doctype html><html> <head> <title>登陆页</title> <link rel="stylesheet" href="/d/file/titlepic/bootstrap.min.css" integrity="sha384-mcw98/sfnge8fjt3gxweongsv7zt27nxfoaoapmym81iuxopkfojwj8erdknlpmo" crossorigin="anonymous"> </head> <body> <div class="container"> <div class="card col-12 mt-5"> <div class="card-body"> <h4 class="card-title"> 用户登录 </h4> <div class="col-12 mt-4 d-flex justify-content-center"> <form class="col-8" method="post" action="action.php"> <input type="hidden" name="action" value="login"> <div class="form-group"> <label for="urname">用户名</label> <input type="text" class="form-control" id="urname" name="urname" placeholder="请输入用户名"> </div> <div class="form-group"> <label for="password">密码</label> <input type="password" class="form-control" id="password" name="password" placeholder="请输入密码"> </div> <div class="form-group form-check"> <input type="checkbox" class="form-check-input" id="remember" name="remember"> <label class="form-check-label" for="remember"> 在这台电脑上记住我的登录状态 </label> </div> <button type="submit" class="btn btn-primary"> 登录 </button> </form> </div> </div> 大学自习课 </div> </div> </body></html>
登录功能实现action.php
<?php ssion_start(); switch ($_request['action']) { ca 'login': $urname = $_post['urname']; $password = $_post['password']; $remember = $_post['remember']; $ur = getur(); if ($urname != $ur['urname']) { // 登录失败 ndloginfailedrespon(); } if ($password != $ur['password']) { // 登录失败 ndloginfailedrespon(); } if ($remember) { rememberlogin($urname); } $_ssion['urname'] = $urname; header("location:index.php"); break; ca 'logout': ssion_unt(); tcookie("urname", "", time() - 1); header("location:login.php"); break; } function getur() { return array( "urname" => "cyy", "password" => "123456" ); } function ndloginfailedrespon() { $respon = "<script> alert('用户名或密码错误！'); window.location='login.php'; </script>"; echo $respon; die; } function rememberlogin($urname) { tcookie("urname", $urname, time() + 7 * 24 * 3600); }首页index.php
<?php ssion_start(); if (rememberedlogin()) { $_ssion['urname'] = $_cookie['urname']; } if (!hasloggedin()) { header("location:login.php"); die; } function hasloggedin() { return ist($_ssion['urname']) && validateurname($_ssion['urname']); } function validateurname($urname) { return $urname == "cyy"; } function rememberedlogin() { return ist($_cookie['urname']) && validateurname($_cookie['urname']); } ?> <!doctype html> <html> <head> <title>主页</title> <link rel="stylesheet" href="/d/file/titlepic/bootstrap.min.css" integrity="sha384-mcw98/sfnge8fjt3gxweongsv7zt27nxfoaoapmym81iuxopkfojwj8erdknlpmo" crossorigin="anonymous"> </head> <body> <div class="container"> <nav class="navbar navbar-light bg-light"> <a class="navbar-brand"> 使用 cookie 和 ssion 实现会话控制 </a> <a href="action.php?action=logout"> <button class="btn btn-outline-danger my-2 my-sm-0" type="button"> 注销 </button> </a> </nav> <div class="d-flex justify-content-around mt-5"> <div class="card col-5"> <div class="card-body"> <h5 class="card-title"> 会话控制实战内容一 </h5> <h6 class="card-subtitle mb-2 text-muted"> 成人高考英语作文万能句子 ssion 部分 </h6> <p class="card-text"> 实现用户认证功能，用户登录、退出与身份识别 </p> </div> </div> <div class="card col-5"> <div class="card-body"> <h5 class="card-title"> 会话控制实战内容二 </h5> <h6 class="card-subtitle mb-2 text-muted"> cookie 部分 </h6> <p class="card-text"> 实现登录记住用户功能，七天免登录认证 </p> </div> </div> </div> <div class="d-flex justify-content-around mt-4"> <div class="card col-5"> <div class="card-body"> <h5 class="card-title"> 会话控制实战内容一 </h5> <h6 class="card-subtitle mb-2 text-muted"> ssion 部分 </h6> <p class="card-text"> 实现用户认证功能，用户登录、退出与身份识别 </p> </div> </div> <div class="cdnf搬砖哪里最好ard col-5"> <div class="card-body"> <h5 class="card-title"> 会话控制实战内容二 </h5> <h6 class="card-subtitle mb-2 text-muted"> cookie 部分 </h6> <p class="card-text"> 实现登录记住用户功能，七天免登录认证 </p> </div> </div> </div> </div> </body> </html>接下来是会话控制实例：许愿墙源码

知识点补充：
【使用 cookie 实现会话控制】
用于存储用户关键信息
保存在客户端（浏览器）
通过 http 请求/响应头传输
【cookie 失效】
cookie过期
用户手动删除 cookie
服务器清除 cookie 的有效性
【使用 ssion 实现会话控制】
用于存储用户相关信息
保存在服务端
通过保存在客户端的 ssion id 来定位 ssion 内容
【ssion 失效/清除】
cookie过期（关闭浏览器）
用户手动删除 cookie
服务端删除 ssion 文件或清空 ssion 内容
