下面本篇文章主要给大家介绍一下PHP+swoole如何实现简单多人在线聊天群发，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。

由于本文的能力有限，有好多聊天逻辑的细节没有实现，只实现了群发，具体代码如下所示：

php代码：

$serv = new swoole_websocket_server("127.0.0.1",3999);
//服务的基本设置
$serv->set(array(
&#39;worker_num&#39; => 2,
&#39;reactor_num&#39;=>8,
&#39;task_worker_num&#39;=>1,
&#39;dispatch_mode&#39; => 2,
&#39;debug_mode&#39;=> 1,
&#39;daemonize&#39; => true,
&#39;log_file&#39; => __DIR__.&#39;/log/webs_swoole.log&#39;,
&#39;heartbeat_check_interval&#39; => 60,
&#39;heartbeat_idle_time&#39; => 600,
));
$serv->on(&#39;connect&#39;, function ($serv,$fd){
// echo "client:$fd Connect.".PHP_EOL;
});
//测试receive
$serv->on("receive",function(swoole_server $serv,$fd,$from_id,$data){
// echo "receive#{$from_id}: receive $data ".PHP_EOL;
});
$serv->on(&#39;open&#39;, function($server, $req) {
// echo "server#{$server->worker_pid}: handshake success with fd#{$req->fd}".PHP_EOL;;
// echo PHP_EOL;
});
$serv->on(&#39;message&#39;,function($server,$frame) {
// echo "message: ".$frame->data.PHP_EOL;
$msg=json_decode($frame->data,true);
switch ($msg[&#39;type&#39;]){
case &#39;login&#39;:
$server->push($frame->fd,"欢迎欢迎~");
break;
default:
break;
}
$msg[&#39;fd&#39;]=$frame->fd;
$server->task($msg);
});
$serv->on("workerstart",function($server,$workerid){
// echo "workerstart: ".$workerid.PHP_EOL;
// echo PHP_EOL;
});
$serv->on("task","on_task");
$serv->on("finish",function($serv,$task_id,$data){
return ;
});
$serv->on(&#39;close&#39;, function($server,$fd,$from_id) {
// echo "connection close: ".$fd.PHP_EOL;
// echo PHP_EOL;
});
$serv->start();
function on_task($serv,$task_id,$from_id,$data) {
switch ($data[&#39;type&#39;]){
case &#39;login&#39;:
$send_msg="说:我来了~";
break;
default:
$send_msg="说:{$data[&#39;msg&#39;][&#39;speak&#39;]}";
break;
}
foreach ($serv->connections as $conn){
if ($conn!=$data[&#39;fd&#39;]){
if (strpos($data[&#39;msg&#39;][&#39;name&#39;],"游客")===0){
$name=$data[&#39;msg&#39;][&#39;name&#39;]."_".$data[&#39;fd&#39;];
}else{
$name=$data[&#39;msg&#39;][&#39;name&#39;];
}
}else{
$name="我";
}
$serv->push($conn,$name.$send_msg);
}
return;
}
function on_finish($serv,$task_id,$data){
return true;
}
