php代码：
<?php
use Workerman\Worker;
require_once '../Autoloader.php';//注意 这里要看你的workerman里的这个文件在哪 然后在进行修改
$global_uid = 0;
// 当客户端连上来时分配uid，并保存连接，并通知所有客户端
function handle_connection($connection) {
global $text_worker, $global_uid;
// 为这个链接分配一个uid
$connection->uid = ++$global_uid;
foreach ($text_worker->connections as $conn) {
$conn->send("user[{$connection->uid}] online");
}
}
// 当客户端发送消息过来时，转发给所有人
function handle_message($connection, $data) {
global $text_worker;
foreach ($text_worker->connections as $conn) {
$conn->send("user[{$connection->uid}] said: $data");
}
}
// 当客户端断开时，广播给所有客户端
function handle_close($connection) {
global $text_worker;
foreach ($text_worker->connections as $conn) {
$conn->send("user[{$connection->uid}] logout");
}
}
$text_worker = new Worker("websocket://0.0.0.0:2347");
$text_worker->count = 1;
$text_worker->onConnect = 'handle_connection';
$text_worker->onMessage = 'handle_message';
$text_worker->onClose = 'handle_close';
