$worker = new Worker('websocket://0.0.0.0:1234');和$inner_text_worker = new Worker('Text://0.0.0.0:5678');監(jiān)聽的是不同的端口，但是是同一個(gè)進(jìn)程，同一個(gè)進(jìn)程間全局變量是可以互相訪問的，例如uid到連接對(duì)象的映射($worker->uidConnections)

$worker->onWorkerStart = function($worker)
{
    $inner_text_worker = new Worker('Text://0.0.0.0:5678');
     $inner_text_worker->onMessage = function($connection, $buffer)use($worker)
     {
        global $worker;
        $data = json_decode($buffer, true);
        $uid = $data;
        $buffer = $data;
        $ret = sendMessageByUid($uid, $buffer);
        // $connection->send($ret ? 'ok' : 'fail');
        $connection->send($worker->data);//但發(fā)覺只能是第一次獲取到數(shù)據(jù)，后面都是空的了。
     };
     $inner_text_worker->listen();
};
$worker->onConnect = function($connection)
{
    echo "new connection from ip " . $connection->getRemoteIp() . "\n";
};
$worker->uidConnections = array();
$worker->onMessage = function($connection, $data)use($worker)
{
     if(!isset($connection->uid))
     {
        $connection->uid = $data;
        $worker->uidConnections = $connection;
        return;
     }
     $worker->data = $data;//添加一個(gè)屬性
};

而且 $inner_text_worker = new Worker('Text://0.0.0.0:5678');第一次發(fā)送數(shù)據(jù)到$worker = new Worker('Text://0.0.0.0:1234');的時(shí)候$worker->data也是為空的，這樣也不符合要求。

還有如果是多設(shè)備的情況，會(huì)不會(huì)有部分設(shè)備不能接收到數(shù)據(jù)呢？謝謝！

不會(huì)

那么$inner_text_worker如何能及時(shí)的收到$worker->onMessage里面發(fā)過來的數(shù)據(jù)呢？

$inner_text_worker不會(huì)收到$worker->onMessage發(fā)來的數(shù)據(jù)，但是$worker->onMessage收到的數(shù)據(jù)可以轉(zhuǎn)發(fā)給$inner_text_worker的連接。同樣的，反過來也可以。
這個(gè)例子實(shí)際上就是$inner_text_worker->onMessage收到的數(shù)據(jù)轉(zhuǎn)發(fā)給了$worker的連接，也就是轉(zhuǎn)發(fā)給了websocket的連接。

還請(qǐng)老大在代碼上指點(diǎn)一二，謝謝。
