🚀 Speed up Laravel/Lumen by
Swoole, let's fly.
-
Built-in Http/WebSocket server
-
Memory resident
-
Gracefully reload
-
Automatically reload when code is modified
-
Support Laravel/Lumen both, good compatibility
-
Simple & Out of the box
| Dependency | Requirement |
|---|---|
| PHP | >= 5.5.9 |
| Swoole | >= 1.7.19 The Newer The Better No longer support PHP5 since 2.0.12 |
| Laravel/Lumen | >= 5.1 |
| Gzip[optional] | zlib, be used to compress the HTTP response, check by ldconfig -p|grep libz |
| Inotify[optional] | inotify, be used to reload all worker processes when your code is modified, check by php --ri inotify |
1.Require package via Composer(packagist).
# Run in the root path of your Laravel/Lumen project.
composer require "hhxsv5/laravel-s:~1.0" -vvv
# Make sure that your composer.lock file is under the VCS2.Register service provider.
Laravel: inconfig/app.phpfile
'providers' => [
//...
Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class,
],Lumen: inbootstrap/app.phpfile
$app->register(Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class);3.Publish configuration.
Suggest that do publish after upgrade LaravelS every time
php artisan laravels publishSpecial for Lumen: you DO NOT need to load this configuration manually in bootstrap/app.php file, LaravelS will load it automatically.
// Unnecessary to call configure()
$app->configure('laravels');4.Change config/laravels.php: listen_ip, listen_port, refer Settings.
php artisan laravels {start|stop|restart|reload|publish}
| Command | Description |
|---|---|
start |
Start LaravelS, list the processes by ps -ef|grep laravels |
stop |
Stop LaravelS |
restart |
Restart LaravelS |
reload |
Reload all worker processes(Contain your business & Laravel/Lumen codes), exclude master/manger process |
publish |
Publish configuration file laravels.php into folder config |

</VirtualHost>The Listening address of WebSocket Sever is the same as Http Server.
1.Create WebSocket Handler class, and implement interface WebSocketHandlerInterface.
namespace App\Services;
use Hhxsv5\LaravelS\Swoole\WebSocketHandlerInterface;
/**
* @see https://www.swoole.co.uk/docs/modules/swoole-websocket-server
*/
class WebSocketService implements WebSocketHandlerInterface
{
// Declare constructor without parameters
public function __construct()
{
}
public function onOpen(\swoole_websocket_server $server, \swoole_http_request $request)
{
// Laravel has finished its lifetime before triggering onOpen event, so Laravel's Request & Session are available here, Request is readable only, Session is readable & writable both.
\Log::info('New WebSocket connection', [$request->fd, request()->all(), session()->getId(), session('xxx'), session(['yyy' => time()])]);
$server->push($request->fd, 'Welcome to LaravelS');
// throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them
}
public function onMessage(\swoole_websocket_server $server, \swoole_websocket_frame $frame)
{
\Log::info('Received message', [$frame->fd, $frame->data, $frame->opcode, $frame->finish]);
$server->push($frame->fd, date('Y-m-d H:i:s'));
// throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them
}
public function onClose(\swoole_websocket_server $server, $fd, $reactorId)
{
// throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them
}
}2.Modify config/laravels.php.
// ...
'websocket' => [
'enable' => true,
'handler' => \App\Services\WebSocketService::class,
],
'swoole' => [
//...
// Must set dispatch_mode in (2, 4, 5), see https://www.swoole.co.uk/docs/modules/swoole-server/configuration
'dispatch_mode' => 2,
//...
],
// ...3.Use swoole_table to bind FD & UserId, optional, Swoole Table Demo. Also you can use the other global storage services, like Redis/Memcached/MySQL, but be careful that FD will be possible conflicting between multiple Swoole Servers.
4.Cooperate with Nginx (Recommended)
Refer WebSocket Proxy

});This feature depends on
AsyncTaskofSwoole, your need to setswoole.task_worker_numinconfig/laravels.phpfirstly. The performance of asynchronous event processing is influenced by number of Swoole task process, you need to set task_worker_num appropriately.
1.Create event class.
use Hhxsv5\LaravelS\Swoole\Task\Event;
class TestEvent extends Event
{
private $data;
public function __construct($data)
{
$this->data = $data;
}
public function getData()
{
return $this->data;
}
}2.Create listener class.
use Hhxsv5\LaravelS\Swoole\Task\Event;
use Hhxsv5\LaravelS\Swoole\Task\Listener;
class TestListener1 extends Listener
{
// Declare constructor without parameters
public function __construct()

\Log::info(__CLASS__ . ':handle start', [$event->getData()]);
sleep(2);// Simulate the slow codes
// throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them

[
// ...
'events' => [
\App\Tasks\TestEvent::class => [
\App\Tasks\TestListener1::class,

// Create instance of event and fire it, "fire" is asynchronous.
use Hhxsv5\LaravelS\Swoole\Task\Event;
$success = Event::fire(new TestEvent('event data'));
var_dump($success);// Return true if sucess, otherwise falseThis feature depends on
AsyncTaskofSwoole, your need to setswoole.task_worker_numinconfig/laravels.phpfirstly. The performance of task processing is influenced by number of Swoole task process, you need to set task_worker_num appropriately.
1.Create task class.
use Hhxsv5\LaravelS\Swoole\Task\Task;
class TestTask extends Task
{
private $data;
private $result;
public function __construct($data)
{
$this->data = $data;
}
// The logic of task handling, run in task process, CAN NOT deliver task
public function handle()
{
\Log::info(__CLASS__ . ':handle start', [$this->data]);
sleep(2);// Simulate the slow codes
// throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them
$this->result = 'the result of ' . $this->data;
}
// Optional, finish event, the logic of after task handling, run in worker process, CAN deliver task
public function finish()
{
\Log::info(__CLASS__ . ':finish start', [$this->result]);
Task::deliver(new TestTask2('task2 data')); // Deliver the other task
}
}2.Deliver task.
// Create instance of TestTask and deliver it, "deliver" is asynchronous.
use Hhxsv5\LaravelS\Swoole\Task\Task;
$task = new TestTask('task data');
// $task->delay(3);// delay 3 seconds to deliver task
$ret = Task::deliver($task);
var_dump($ret);// Return true if sucess, otherwise falseWrapper cron job base on Swoole's Millisecond Timer, replace
LinuxCrontab.
1.Create cron job class.
namespace App\Jobs\Timer;
use Hhxsv5\LaravelS\Swoole\Timer\CronJob;
class TestCronJob extends CronJob
{
protected $i = 0;
// Declare constructor without parameters
public function __construct()
{
}
public function interval()
{
return 1000;// Run every 1000ms
}
public function isImmediate()
{
return false;// Whether to trigger `run` immediately after setting up
}
public function run()
{
\Log::info(__METHOD__, ['start', $this->i, microtime(true)]);
// do something
$this->i++;
\Log::info(__METHOD__, ['end', $this->i, microtime(true)]);
if ($this->i >= 10) { // run 10 times only
\Log::info(__METHOD__, ['stop', $this->i, microtime(true)]);
$this->stop(); // stop this cron job
}
// throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them
}
}2.Bind cron job.
// Bind cron jobs in file "config/laravels.php"
[
// ...
'timer' => [
'enable' => true, // Enable Timer
'jobs' => [ // the list of cron job
// Enable LaravelScheduleJob to run `php artisan schedule:run` every 1 minute, replace Linux Crontab
//\Hhxsv5\LaravelS\Illuminate\LaravelScheduleJob::class,
\App\Jobs\Timer\TestCronJob::class,
],
],
// ...
];3.Note: it will launch multiple timers when build the server cluster, so you need to make sure that launch one timer only to avoid running repetitive task.

$swoole = app('swoole');
var_dump($swoole->stats());// Singleton1.Define swoole_table, support multiple.
All defined tables will be created before Swoole starting.
// in file "config/laravels.php"
[
// ...
'swoole_tables' => [
// Scene:bind UserId & FD in WebSocket
'ws' => [// The Key is table name, will add suffix "Table" to avoid naming conficts. Here defined a table named "wsTable"
'size' => 102400,// The max size
'column' => [// Define the columns
['name' => 'value', 'type' => \swoole_table::TYPE_INT, 'size' => 8],
],
],
//...Define the other tables
],
// ...
];2.Access swoole_table: all table instances will be bound on swoole_server, access by app('swoole')->xxxTable.
// Scene:bind UserId & FD in WebSocket
public function onOpen(\swoole_websocket_server $server, \swoole_http_request $request)
{
// var_dump(app('swoole') === $server);// The same instance
$userId = mt_rand(1000, 10000);
app('swoole')->wsTable->set('uid:' . $userId, ['value' => $request->fd]);// Bind map uid to fd
app('swoole')->wsTable->set('fd:' . $request->fd, ['value' => $userId]);// Bind map fd to uid
$server->push($request->fd, 'Welcome to LaravelS');
}
public function onMessage(\swoole_websocket_server $server, \swoole_websocket_frame $frame)
{
foreach (app('swoole')->wsTable as $key => $row) {
if (strpos($key, 'uid:') === 0) {
$server->push($row['value'], 'Broadcast: ' . date('Y-m-d H:i:s'));// Broadcast
}
}
}
public function onClose(\swoole_websocket_server $server, $fd, $reactorId)
{
$uid = app('swoole')->wsTable->get('fd:' . $fd);
if ($uid !== false) {
app('swoole')->wsTable->del('uid:' . $uid['value']); // Ubind uid map
}
app('swoole')->wsTable->del('fd:' . $fd);// Unbind fd map
$server->push($fd, 'Goodbye');
}For more information, please refer to Swoole Server AddListener
To make our main server support more protocols not just Http and WebSocket, we bring the feature multi-port mixed protocol of Swoole in LaravelS and name it Socket. Now, you can build TCP/UDP applications easily on top of Laravel.
- Create socket handler class, and extend
Hhxsv5\LaravelS\Swoole\Socket\{TcpSocket|UdpSocket|Http|WebSocket}.
namespace App\Sockets;
use Hhxsv5\LaravelS\Swoole\Socket\TcpSocket;
class TestTcpSocket extends TcpSocket
{
public function onConnect(\swoole_server $server, $fd, $reactorId)
{
\Log::info('New TCP connection', [$fd]);
$server->send($fd, 'Welcome to LaravelS.');
}
public function onReceive(\swoole_server $server, $fd, $reactorId, $data)
{
\Log::info('Received data', [$fd, $data]);
$server->send($fd, 'LaravelS: ' . $data);
if ($data === "quit\r\n") {
$server->send($fd, 'LaravelS: bye' . PHP_EOL);
$server->close($fd);
}
}
public function onClose(\swoole_server $server, $fd, $reactorId)
{
\Log::info('New TCP connection', [$fd]);
$server->send($fd, 'Goodbye');
}
}These Socket connections share the same worker processes with your HTTP/WebSocket connections. So it won't be a problem at all if you want to deliver tasks, use swoole_table, even Laravel components such as DB, Eloquent and so on.
At the same time, you can access swoole_server_port object directly by member property swoolePort.
public function onReceive(\swoole_server $server, $fd, $reactorId, $data)
{
$port = $this->swoolePort; //There you go
}- Register Sockets.

-
Singleton Issue-
Under FPM mode, singleton instances will be instantiated and recycled in every request, request start=>instantiate instance=>request end=>recycled instance.
-
Under Swoole Server, All singleton instances will be held in memory, different lifetime from FPM, request start=>instantiate instance=>request end=>do not recycle singleton instance. So need developer to maintain status of singleton instances in ervery request.
-
Common solutions:
-
Resetstatus of singleton instances byMiddleware. -
Re-register
ServiceProvider, addXxxServiceProviderintoregister_providersof filelaravels.php. So that reinitialize singleton instances in ervery request Refer.

-
Get all info of request from
Illuminate\Http\RequestObject, compatible with $_SERVER/$_ENV/$_GET/$_POST/$_FILES/$_COOKIE/$_REQUEST,CANNOT USE$_SESSION.
