首先你需要多看下文檔，定時器不建議寫在onMessage回調(diào)。

從你代碼中大致得出定時器主要做一件事：那就是心跳檢測。

如下為大概示例：

<?php
?
require_once __DIR__ . '/Workerman/Autoloader.php';
?
?
use Workerman\Worker;
use Workerman\Lib\Timer;

$worker = new Worker('tcp://0.0.0.0:1234');

$worker->onWorkerStart = function($worker) {
    // 防止開多進程
    if ($worker->id === 0) {
        Timer::add(10, function()use($worker) {
            foreach($worker->connections as $connection) {
                $connection->send('{"type":"ping"}');
            }
        });
    }
};
?
$worker->onConnect = function($connection) {
};

$worker->onMessage = function($connection, $data) {
    global $worker;
    $connection->lastMessageTime = time();
    $data = json_decode($data, true);
    $_SESSION['hotel_price'] = '';
    switch ($data['type']) {
        case 'login':
            $where['id'] = $data['id'];
            $where['token'] = $data['token'];
            $id = Db::name('business')->where($where)->value('id');
            if ($id) {
                $connection->uid = $id; //設置當前客戶端id
                $worker->uidConnections[$connection->uid] = $connection; //保存到服務器里
                $connection->send('{"type":"login","msg":"登錄成功"}');
            } else {
                $connection->timer_id = '';
                $connection->uid = $data['id'] . $data['token'];
                $worker->uidConnections[$connection->uid] = $connection; //保存到服務器里
                $connection->send('{"type":"login","msg":"登錄失敗"}');
                $connection->close();
            }
            break;
    }
};

// 如果不是在根目錄啟動，則運行runAll方法
if(!defined('GLOBAL_START')) {
    Worker::runAll();
}
