我来详细介绍PHP实现防沉迷系统的几种方案：

基础实名认证 + 时间控制

数据库设计

CREATE TABLE users (
    id INT PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(50) NOT NULL,
    id_card VARCHAR(18) NOT NULL,  -- 身份证号
    real_name VARCHAR(50) NOT NULL,
    birthday DATE NOT NULL,        -- 出生日期
    status TINYINT DEFAULT 1,      -- 1:正常 0:冻结
    created_at TIMESTAMP
);
CREATE TABLE play_records (
    id INT PRIMARY KEY AUTO_INCREMENT,
    user_id INT NOT NULL,
    play_date DATE NOT NULL,
    start_time DATETIME,
    end_time DATETIME,
    duration INT DEFAULT 0,        -- 累计时长(分钟)
    FOREIGN KEY (user_id) REFERENCES users(id)
);

核心防沉迷逻辑

年龄验证类

        $birthDate = new DateTime("$birthYear-$birthMonth-$birthDay");
        $now = new DateTime();
        $age = $now->diff($birthDate)->y;

}

调用示例

// 使用示例
$db = new mysqli('localhost', 'username', 'password', 'database');
$anti = new AntiAddiction($db);
// 检查游戏状态
$result = $anti->checkPlayStatus(1);
if ($result['can_play']) {
    echo "可以开始游戏，剩余时间：" . $result['remaining_time'] . "分钟";
    $anti->startPlay(1);
} else {
    echo $result['msg'];
    exit;
}
// 游戏结束
$anti->endPlay(1);

API接口设计

<?php
// api.php
header('Content-Type: application/json');
$action = $_GET['action'] ?? '';
$userId = (int)($_POST['user_id'] ?? 0);
$anti = new AntiAddiction($db);
switch ($action) {
    case 'check':
        $result = $anti->checkPlayStatus($userId);
        break;
    case 'start':
        $result = $anti->startPlay($userId);
        break;
    case 'end':
        $result = $anti->endPlay($userId);
        break;
    default:
        $result = ['code' => 400, 'msg' => 'Invalid action'];
}
echo json_encode($result);

高级功能补充

跨平台时长累计

// 使用session或redis存储跨端数据
class CrossPlatformCounter {
    private $redis;
    public function addTime($userId, $platform, $duration) {
        $key = "user:{$userId}:playtime:".date('Y-m-d');
        $this->redis->incrBy($key, $duration);
        $this->redis->expire($key, 24*3600);
    }
    public function getTotalTime($userId) {
        // 从各个平台汇总
        return $this->redis->get("user:{$userId}:playtime:".date('Y-m-d'));
    }
}

定时任务清理

// cron.php - 每天凌晨执行
$sql = "DELETE FROM play_records WHERE play_date < DATE_SUB(NOW(), INTERVAL 7 DAY)";
$db->query($sql);

前端配合

// 前端定时检查
setInterval(async () => {
    const response = await fetch('/api.php?action=check', {
        method: 'POST',
        body: new URLSearchParams({ user_id: userId })
    });
    const data = await response.json();
    if (!data.can_play) {
        alert(data.msg);
        // 强制退出游戏
        location.href = '/logout.php';
    }
}, 60000); // 每分钟检查一次
