index.phph文件

  1. <?php
  2. //开启会话
  3. session_start();
  4. var_dump( $_SESSION['name']);
  5. if(isset($_SESSION['name']) && $_SESSION['name']==='admin'){
  6.     echo '用户：'.$_SESSION['name'].'已登录';
  7.     echo '<a href="dispatch.php?action=logout">请登录</a>a>';
  9. }else{
  10. //    未登录
  11.     echo '没有登录';
  12. echo '<a href="login.php">请登录</a>';
  13. }

login.php

  1. <?php
  2. // 防止用户重复登录
  3. if (isset($_SESSION['name'])) {
  4.     echo '不要重复登录';
  5.     require __DIR__.'/index.php';
  6. }
  7. ?>
  8. <!doctype html>
  9. <html lang="en">
  10. <head>
  11.     <meta charset="UTF-8">
  13.     <title>用户登录</title>
  14. </head>
  16. <form  method="POST" action="check.php">
  17.     <label for="name">手机号：</label><br>
  18. <input type="phone" name="phone" id="phone"><br>
  19.     <label for="password">密码：</label><br>
  20.     <input type="password" name="password" id="password"><br>
  21.     <button>提交</button>
  22. </form>
  23. </body>
  24. </html>

check.php

  1. <?php
  2. session_start();
  3. //链接数据库
  4. require __DIR__ .'/connect.php';
  5. // 1.判断用户的请求类型是否正确?
  6. if ($_SERVER['REQUEST_METHOD'] === 'POST') {
  7.     // 2.获取表单数据
  9.     $phone = $_POST['phone'];
  12.     $password = sha1($_POST['password']);
  14.     // 3. 用用户表user.dbf进行验证
  15.     $sql = 'SELECT * FROM `user` WHERE `phone` = :phone';
  17.     $stmt = $pdo->prepare($sql);
  20.     $stmt->execute();
  21.     $user = $stmt->fetch(PDO::FETCH_ASSOC);
  24.     // 4. 判断验证的结果
  25.     if (false === $user) {
  26.         // 验证失败,返回上一下页面
  27.         echo '<script>alert("验证失败");history.back();</script>';
  28.         die;
  29.     }
  30. echo $user['phone'];
  31.     // 验证成功，将用户的信息写到session
  32.     $_SESSION['name'] = $user['name'];
  34.     echo '<script>alert("登录成功");location.assign("index.php");</script>';
  35.     exit;
  36. } else {
  37.     die('请求类型错误');
  38. }

这里验证总是失败一直找不到原因

logout.php

  1. <?php
  3. // 必须在用户已经登录的情况下再退出
  4. if (isset($_SESSION['name'])) {
  5.     session_destroy();
  6.     echo '退出成功';
  8. } else {
  9.     // 要求用户先登录
  10.     echo '<script>alert("请先登录");location.assign("login.php");</script>';
  11. }
