这篇文章主要为大家详细介绍了基于swoole实现多人聊天室，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了swoole创建多人多房间聊天室的具体代码，供大家参考，具体内容如下
核心的swoole代码
基本的cs(client-sercer)结构不变,这里利用的是redis的哈希和set来储存和分组;从而达到了分组,统计,定时推送等功能;最后利用onclose事件来剔除断开的连接,全部代码如下:(没做前端,就不展示了)
核心的swoole ws.php
<?php
namespace app\common;

'worker_num' => 4,
'task_worker_num' => 2,
// 'heartbeat_check_interval' => 5,
// 'heartbeat_idle_time' => 10,
]);
//监听新端口
$this->server=$this->ws->listen("127.0.0.1", 9502, SWOOLE_SOCK_TCP);
//关闭websocket模式
$this->server->set([
'open_websocket_protocol' => false,
]);
$this->ws->on("start", [$this, 'onStart']);
$this->ws->on('open',[$this,'onopen']);
$this->server->on("receive", [$this, 'onReceive']);
$this->ws->on('task',[$this,'onTask']);

$this->ws->on('message',[$this,'onmessage']);
$this->ws->on('close',[$this,'onclose']);
$this->server->on("close", [$this, 'oncloses']);
$this->ws->start();
}
//监听数据接收事件

// echo "集群是:".print_r($push_arr);
foreach ($push_arr as $v) {
