如何利用PHP和Unity3D结合Workerman实现游戏物品交易系统

// 引入Workerman库
require_once __DIR__ . '/workerman/Autoloader.php';

// 创建一个Workerman实例
$worker = new Worker('tcp://127.0.0.1:1234');

// 设置进程数
$worker->count = 4;

// 当有客户端连接时触发的回调函数
$worker->onConnect = function($connection){
    echo "New connection
";
};

// 当接收到客户端消息时触发的回调函数
$worker->onMessage = function($connection, $data){
    echo "Received message: " . $data . "
";
};

// 启动服务器
Worker::runAll();

// 当接收到客户端消息时触发的回调函数
$worker->onMessage = function($connection, $data){
    // 解析客户端发来的JSON数据
    $message = json_decode($data, true);

    // 获取玩家请求的操作类型
    $action = $message['action'];

    // 根据操作类型执行相应的逻辑
    switch($action){
        case 'request_trade':
            $result = handleTradeRequest($message);
            $connection->send(json_encode($result));
            break;
        case 'confirm_trade':
            $result = handleTradeConfirmation($message);
            $connection->send(json_encode($result));
            break;
        default:
            $connection->send(json_encode(['error' => 'Invalid action']));
            break;
    }
};

// 处理物品交易请求
function handleTradeRequest($message){
    // 根据客户端发来的数据进行物品交易请求的处理逻辑

    // 返回交易结果
    return ['result' => 'success'];
}

// 处理物品交易确认
function handleTradeConfirmation($message){
    // 根据客户端发来的数据进行物品交易确认的处理逻辑

    // 返回确认结果
    return ['result' => 'success'];
}
