Many details of the chat logic are not implemented, only group messaging is implemented.

php code: 

$serv = new swoole_websocket_server("127.0.0.1",3999);

//服务的基本设置
$serv->set(array(
		'worker_num' => 2,
		'reactor_num'=>8,
		'task_worker_num'=>1,
		'dispatch_mode' => 2,
		'debug_mode'=> 1,
		'daemonize' => true,
		'log_file' => __DIR__.'/log/webs_swoole.log',
		'heartbeat_check_interval' => 60,
		'heartbeat_idle_time' => 600,
));

$serv->on('connect', function ($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;
});

$serv->on('open', function($server, $req) {
// 	echo "server#{$server->worker_pid}: handshake success with fd#{$req->fd}".PHP_EOL;;
// 	echo PHP_EOL;
});

$serv->on('message',function($server,$frame) {
// 	echo "message: ".$frame->data.PHP_EOL;
	$msg=json_decode($frame->data,true);
	switch ($msg['type']){
		case 'login':
			$server->push($frame->fd,"欢迎欢迎~");
			break;
		default:
			break;
	}
	$msg['fd']=$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 ;
});
$serv->on('close', function($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['type']){
		case 'login':
			$send_msg="说:我来了~";
			break;
		default:
			$send_msg="说:{$data['msg']['speak']}";
			break;
	}
	foreach ($serv->connections as $conn){
		if ($conn!=$data['fd']){
			if (strpos($data['msg']['name'],"游客")===0){
				$name=$data['msg']['name']."_".$data['fd'];
			}else{
				$name=$data['msg']['name'];
			}
		}else{
			$name="我";
		}
		$serv->push($conn,$name.$send_msg);
	}
	return;
}

function on_finish($serv,$task_id,$data){
	return true;
}

The above introduces the use of swoole in PHP to implement a simple multi-person online chat group, including various aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
