php 代码

<?php

$ws = new swoole_websocket_server("0.0.0.0", 9502);

// 设置配置

$ws->set(

array(

'daemonize' => false, // 是否是守护进程

'max_request' => 10000, // 最大连接数量

'dispatch_mode' => 2,

'debug_mode'=> 1,

// 心跳检测的设置，自动踢掉掉线的fd

'heartbeat_check_interval' => 5,

'heartbeat_idle_time' => 600,

)

);

//监听WebSocket连接打开事件

$ws->on('open', function ($ws, $request) {

$ws->push($request->fd, "hello, welcome to chatroom\n");

});

//监听WebSocket消息事件，其他：swoole提供了bind方法，支持uid和fd绑定

$ws->on('message', function ($ws, $frame) {

$msg = 'from'.$frame->fd.":{$frame->data}\n";

// 分批次发送

$start_fd = 0;

while(true)

{

// connection_list函数获取现在连接中的fd

$conn_list = $ws->connection_list($start_fd, 100); // 获取从fd之后一百个进行发送

var_dump($conn_list);

echo count($conn_list);

if($conn_list === false || count($conn_list) === 0)

{

echo "finish\n";

return;

}

$start_fd = end($conn_list);

foreach($conn_list as $fd)

{

$ws->push($fd, $msg);

}

});

//监听WebSocket连接关闭事件

$ws->on('close', function ($ws, $fd) {

echo "client-{$fd} is closed\n";

$ws->close($fd); // 销毁fd链接信息

});

$ws->start();

然后服务器端直接php swoole.php启动swoole就行，多个浏览器访问swoole.html页面，可以模拟聊天室，查看推送。
