workman在服务器端创建websocet服务

代码如下

count = 1;

// 新增加一个属性，用来保存uid到connection的映射(uid是用户id或者客户端唯一标识)
$worker->uidConnections = array();
$worker->meet_time=array();
$worker->meet_id=array();

{
    // 有新的客户端连接时，连接数+1
    global $connection_count;
    
    ++$connection_count;
    echo "now connection_count=$connection_count\n";
};
// 进程启动后设置一个每秒运行一次的定时器
$worker->onWorkerStart = function($worker) {
    Timer::add(15, function()use($worker){
        $time_now = time();
        //按会议循环获取会议时长

                }
            }
            //计算剩余时长
            $play_sul_time=$worker->meet_id[$k]['time']-$play_total_time;

// 运行所有的worker（其实当前只定义了一个）
