ThinkPHP using Swoole requires the think-swoole Composer package to be installed, provided the Swoole PECL extension is installed on the system
Install think-swoole by executing the composer command in the project root directory of tp5:
composer require topthink/think-swoole
Say nothing but code directly:
Create a new WebSocket.php controller:
(listening ports confirm server release, pagoda environments also need to add security group rules)
<?php namespace app\home\controller; use think\swoole\Server; class WebSocket extends Server { protected $host = '0.0.0.0'; //Listen on all addresses protected $port = 9501; //Listen on port 9501 protected $serverType = 'socket'; protected $option = [ 'worker_num'=> 4, //Set the number of Worker processes started 'daemonize' => false, //Daemon (go online to true) 'backlog' => 128, //Listen Queue Length 'dispatch_mode' => 2, //Fixed mode to ensure that data from the same connection will only be processed by the same worker //Heart beat detection: traverse all connections every 60 seconds, forcing connections that do not send any data to the server to be closed for 10 minutes 'heartbeat_check_interval' => 60, 'heartbeat_idle_time' => 600 ]; //Callback function when establishing connection public function onOpen($server,$req) { $fd = $req->fd;//Client Identity $uid = $req->get['uid'];//User id passed by client $token = $req->get['token'];//Client-passed user login token //Omit token validation logic... if (!$token) { $arr = array('status'=>2,'message'=>'token Expired'); $server->push($fd, json_encode($arr)); $server->close($fd); return; } //Omit binding fd logic to user... echo "user{$uid}Connection established,Identify as{$fd}\n"; } //Callback function when receiving data public function onMessage($server,$frame) { $fd = $frame->fd; $message = $frame->data; //Omit querying user uid logic via fd... $uid = 666; $data['uid'] = $uid; $data['message'] = 'user'.$uid.'Sent:'.$message; $data['post_time'] = date("m/d H:i",time()); $arr = array('status'=>1,'message'=>'success','data'=>$data); //Push to current connected user only //$server->push($fd, json_encode($arr)); //Push to all connected users foreach($server->connections as $fd) { $server->push($fd, json_encode($arr)); } } //Callback function when connection is closed public function onClose($server,$fd) { echo "Identification{$fd}Connection closed\n"; } }

Server moved to project root to open service:
php public/index.php Websocket/start
The path here is because I have bound the home module as the default module and tp5 defaults to php public/index.php index/Websocket/start)
Open successfully, view port has been listened on:
lsof -i:9501
I believe that many phper s will encounter some problems and bottlenecks when they are advanced. They write too much business code without a sense of direction and don't know where to start to improve. I have sorted out some data about this, including but not limited to: distributed architecture, high scalability, high performance, high concurrency, server performance tuning, TP6, laravel, YII2, Redis, Swoole, Swoft, Kafka, Mysql tuningAdvanced and advanced dry goods needs such as chemicals, shell scripts, Docker, micro-services, Nginx, etc. can be shared free of charge to everyone, need Please click here
