PHP会员管理实现方法

数据库设计 创建会员数据表，包含字段如id、username、password、email、register_time等。使用MySQL的SQL语句如下：

CREATE TABLE `members` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(50) NOT NULL,
  `password` varchar(255) NOT NULL,
  `email` varchar(100) NOT NULL,
  `register_time` datetime NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `username` (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

注册功能实现 创建注册表单页面register.php，处理用户提交的数据：

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $username = trim($_POST['username']);
    $password = password_hash($_POST['password'], PASSWORD_DEFAULT);
    $email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);

    $stmt = $pdo->prepare("INSERT INTO members (username, password, email, register_time) VALUES (?, ?, ?, NOW())");
    $stmt->execute([$username, $password, $email]);

    header('Location: login.php');
    exit;
}
?>

登录功能实现 创建登录页面login.php，验证用户凭证：

<?php
session_start();
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $username = $_POST['username'];
    $password = $_POST['password'];

    $stmt = $pdo->prepare("SELECT * FROM members WHERE username = ?");
    $stmt->execute([$username]);
    $user = $stmt->fetch();

    if ($user && password_verify($password, $user['password'])) {
        $_SESSION['user_id'] = $user['id'];
        header('Location: member_area.php');
        exit;
    }
}
?>

会员区域保护 在需要会员才能访问的页面顶部添加验证代码：

<?php
session_start();
if (!isset($_SESSION['user_id'])) {
    header('Location: login.php');
    exit;
}
$stmt = $pdo->prepare("SELECT * FROM members WHERE id = ?");
$stmt->execute([$_SESSION['user_id']]);
$current_user = $stmt->fetch();
?>

密码重置功能 实现密码重置流程，包括发送重置链接邮件：

function sendResetEmail($email) {
    $token = bin2hex(random_bytes(32));
    $expires = date('Y-m-d H:i:s', strtotime('+1 hour'));

    $stmt = $pdo->prepare("UPDATE members SET reset_token = ?, reset_expires = ? WHERE email = ?");
    $stmt->execute([$token, $expires, $email]);

    $resetLink = "https://example.com/reset_password.php?token=$token";
    mail($email, 'Password Reset', "Click to reset: $resetLink");
}

会员资料管理 允许会员更新个人信息：

<?php
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $newEmail = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);

    $stmt = $pdo->prepare("UPDATE members SET email = ? WHERE id = ?");
    $stmt->execute([$newEmail, $_SESSION['user_id']]);

    header('Location: profile.php?updated=1');
    exit;
}
?>
