workerman使用udp協(xié)議的話，客戶端如何測試發(fā)送數(shù)據(jù)呢？

這是服務端：

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

$global_uid = 0;

// 當客戶端連上來時分配uid，并保存連接，并通知所有客戶端
function handle_connection($connection)
{
    global $text_worker, $global_uid;
    // 為這個鏈接分配一個uid
    $connection->uid = ++$global_uid;
}

// 當客戶端發(fā)送消息過來時，轉(zhuǎn)發(fā)給所有人
function handle_message($connection, $data)
{
    global $text_worker;
    foreach($text_worker->connections as $conn)
    {
        $conn->send("user said: $data");
    }
}

// 當客戶端斷開時，廣播給所有客戶端
function handle_close($connection)
{
    global $text_worker;
    foreach($text_worker->connections as $conn)
    {
        $conn->send("user logout");
    }
}

// 創(chuàng)建一個文本協(xié)議的Worker監(jiān)聽2347接口
$text_worker = new Worker("udp://0.0.0.0:2348");

// 只啟動1個進程，這樣方便客戶端之間傳輸數(shù)據(jù)
$text_worker->count = 1;

$text_worker->onConnect = 'handle_connection';
$text_worker->onMessage = 'handle_message';
$text_worker->onClose = 'handle_close';

Worker::runAll();
