会员管理系统设计思路

会员管理系统通常需要实现用户注册、登录、信息管理、权限控制等功能。以下是一个基础的PHP实现方案：

数据库设计

创建会员数据表members，建议包含以下字段：

CREATE TABLE members (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) NOT NULL UNIQUE,
    password VARCHAR(255) NOT NULL,
    email VARCHAR(100) NOT NULL UNIQUE,
    reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    last_login DATETIME,
    status TINYINT DEFAULT 1,
    user_level INT DEFAULT 1
);

会员注册功能

处理用户注册的表单提交：

// 注册处理逻辑
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    $username = trim($_POST['username']);
    $password = password_hash($_POST['password'], PASSWORD_DEFAULT);
    $email = trim($_POST['email']);

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

    header("Location: login.php");
    exit;
}

会员登录功能

实现用户登录验证：

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'];
        $_SESSION['username'] = $user['username'];

        // 更新最后登录时间
        $update = $pdo->prepare("UPDATE members SET last_login = NOW() WHERE id = ?");
        $update->execute([$user['id']]);

        header("Location: dashboard.php");
        exit;
    } else {
        $error = "用户名或密码错误";
    }
}

会员信息管理

显示和编辑会员信息：

// 获取当前用户信息
$stmt = $pdo->prepare("SELECT * FROM members WHERE id = ?");
$stmt->execute([$_SESSION['user_id']]);
$user = $stmt->fetch();

// 更新信息处理
if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['update_profile'])) {
    $email = trim($_POST['email']);

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

    header("Location: profile.php");
    exit;
}
