Requirements

| Dependency | Requirement | | -------- | -------- | | PHP | >= 5.5.9 Recommend PHP7+ | | Swoole | >= 1.7.19 No longer support PHP5 since 2.0.12 Recommend 4.2.3+ | | Laravel/Lumen | >= 5.1 Recommend 5.6+ |

Install

1.Require package via Composer(packagist).

composer require "hhxsv5/laravel-s:~3.4.0" -vvv
# Make sure that your composer.lock file is under the VCS

2.Register service provider(pick one of two).

• Laravel: in config/app.php file, Laravel 5.5+ supports package discovery automatically, you should skip this step

  'providers' => [
      //...
      Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class,
  ],
  

• Lumen: in bootstrap/app.php file

  $app->register(Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class);
  

3.Publish configuration and binaries.

Suggest that do publish after upgrade LaravelS every time

php artisan laravels publish
# Configuration: config/laravels.php
# Binary: bin/laravels bin/fswatch

4.Change config/laravels.php: listen_ip, listen_port, refer Settings.

Run

php bin/laravels {start|stop|restart|reload|info|help}

Please read the notices carefully before running, Important notices.

| Command | Description | | --------- | --------- | | start | Start LaravelS, list the processes by "ps -ef|grep laravels". Support the option "-d|--daemonize" to run as a daemon; Support the option "-e|--env" to specify the environment to run, such as --env=testing will use the configuration file .env.testing firstly, this feature requires Laravel 5.2+ | | stop | Stop LaravelS | | restart | Restart LaravelS, support the options "-d|--daemonize" and "-e|--env" | | reload | Reload all Task/Worker/Timer processes which contain your business codes, and trigger the method onReload of Custom process, CANNOT reload Master/Manger processes | | info | Display component version information | | help | Display help information |

Deploy

It is recommended to supervise the main process through Supervisord, the premise is without option -d and to set swoole.daemonize to false.

Enable WebSocket server

The Listening address of WebSocket Sever is the same as Http Server.

1.Create WebSocket Handler class, and implement interface WebSocketHandlerInterface.The instant is automatically instantiated when start, you do not need to manually create it.

namespace App\Services;
use Hhxsv5\LaravelS\Swoole\WebSocketHandlerInterface;
use Swoole\Http\Request;
use Swoole\WebSocket\Frame;
use Swoole\WebSocket\Server;
/**
 * @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(Server $server, 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(Server $server, 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(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, // Here is 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 SwooleTable 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

map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
}
upstream laravels {
    # Connect IP:Port

    location =/ws {
        # proxy_connect_timeout 60s;
        # proxy_send_timeout 60s;
        # proxy_read_timeout: Nginx will close the connection if the proxied server does not send data to Nginx in 60 seconds; At the same time, this close behavior is also affected by heartbeat setting of Swoole.

        proxy_set_header Server-Port $server_port;
        proxy_pass http://laravels;
    }
}

5.Heartbeat setting

• Heartbeat setting of Swoole

  // config/laravels.php
  'swoole' => [
      //...
      // All connections are traversed every 60 seconds. If a connection does not send any data to the server within 600 seconds, the connection will be forced to close.
      'heartbeat_idle_time'      => 600,
      'heartbeat_check_interval' => 60,
      //...
  ],
  

• Proxy read timeout of Nginx

  # Nginx will close the connection if the proxied server does not send data to Nginx in 60 seconds
  proxy_read_timeout 60s;
  

Listen events

System events

Usually, you can reset/destroy some global/static variables, or change the current Request/Response object.

• laravels.received_request After LaravelS parsed Swoole\Http\Request to Illuminate\Http\Request, before Laravel's Kernel handles this request.

  // Edit file `app/Providers/EventServiceProvider.php`, add the following code into method `boot`
  // If no variable $events, you can also call Facade \Event::listen(). 
  $events->listen('laravels.received_request', function (\Illuminate\Http\Request $req, $app) {
      $req->query->set('get_key', 'hhxsv5');// Change query of request
      $req->request->set('post_key', 'hhxsv5'); // Change post of request
  });
  

• laravels.generated_response After Laravel's Kernel handled the request, before LaravelS parses Illuminate\Http\Response to Swoole\Http\Response.

  // Edit file `app/Providers/EventServiceProvider.php`, add the following code into method `boot`
  // If no variable $events, you can also call Facade \Event::listen(). 
  $events->listen('laravels.generated_response', function (\Illuminate\Http\Request $req, \Symfony\Component\HttpFoundation\Response $rsp, $app) {
      $rsp->headers->set('header-key', 'hhxsv5');// Change header of response
  });
  

Customized asynchronous events

This feature depends on AsyncTask of Swoole, your need to set swoole.task_worker_num in config/laravels.php firstly. 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\Task;
use Hhxsv5\LaravelS\Swoole\Task\Event;
use Hhxsv5\LaravelS\Swoole\Task\Listener;
class TestListener1 extends Listener
{
    // Declare constructor without parameters
    public function __construct()
    {
    }
    public function handle(Event $event)
    {
        \Log::info(__CLASS__ . ':handle start', [$event->getData()]);
        sleep(2);// Simulate the slow codes
        // Deliver task in CronJob, but NOT support callback finish() of task.
        // Note:
        // 1.Set parameter 2 to true
        // 2.Modify task_ipc_mode to 1 or 2 in config/laravels.php, see https://www.swoole.co.uk/docs/modules/swoole-server/configuration
        $ret = Task::deliver(new TestTask('task data'), true);
        var_dump($ret);
        // throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them
    }
}

3.Bind event & listeners.

// Bind event & listeners in file "config/laravels.php", one event => many listeners
[
    // ...
    'events' => [
        \App\Tasks\TestEvent::class => [
            \App\Tasks\TestListener1::class,
            //\App\Tasks\TestListener2::class,
        ],
    ],
    // ...
];

4.Fire event.

// 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 false

Asynchronous task queue

This feature depends on AsyncTask of Swoole, your need to set swoole.task_worker_num in config/laravels.php firstly. 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 false

Millisecond cron job

Wrapper cron job base on Swoole's Millisecond Timer, replace Linux Crontab.

1.Create cron job class.

namespace App\Jobs\Timer;
use App\Tasks\TestTask;
use Swoole\Coroutine;
use Hhxsv5\LaravelS\Swoole\Task\Task;
use Hhxsv5\LaravelS\Swoole\Timer\CronJob;
class TestCronJob extends CronJob
{
    protected $i = 0;
    // !!! The `interval` and `isImmediate` of cron job can be configured in two ways(pick one of two): one is to overload the corresponding method, and the other is to pass parameters when registering cron job.
    // --- Override the corresponding method to return the configuration: begin
    public function interval()
    {
        return 1000;// Run every 1000ms
    }
    public function isImmediate()
    {
        return false;// Whether to trigger `run` immediately after setting up
    }
    // --- Override the corresponding method to return the configuration: end
    public function run()
    {
        \Log::info(__METHOD__, ['start', $this->i, microtime(true)]);
        // do something
        // sleep(1); // Swoole < 2.1
        Coroutine::sleep(1); // Swoole>=2.1 Coroutine will be automatically created for run().
        $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
            // Deliver task in CronJob, but NOT support callback finish() of task.
            // Note:
            // 1.Set parameter 2 to true
            // 2.Modify task_ipc_mode to 1 or 2 in config/laravels.php, see https://www.swoole.co.uk/docs/modules/swoole-server/configuration
            $ret = Task::deliver(new TestTask('task data'), true);
            var_dump($ret);
        }
        // throw new \Exception('an exception');// all exceptions will be ignored, then record them into Swoole log, you need to try/catch them
    }
}

2.Register cron job.

// Register 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,
            // Two ways to configure parameters:
            // [\App\Jobs\Timer\TestCronJob::class, [1000, true]], // Pass in parameters when registering
            \App\Jobs\Timer\TestCronJob::class, // Override the corresponding method to return the configuration
        ],
        'max_wait_time' => 5, // Max waiting time of reloading
    ],
    // ...
];

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.

4.LaravelS v3.4.0 starts to support the hot restart [Reload] Timer process. After LaravelS receives the SIGUSR1 signal, it waits for max_wait_time(default 5) seconds to end the process, then the Manager process will pull up the Timer process again.

Reload automatically when code is modified

• Via inotify, support Linux only.

  1.Install inotify extension.

  2.Turn on the switch in Settings.

  3.Notice: Modify the file only in Linux to receive the file change events. It's recommended to use the latest Docker. Vagrant Solution.

• Via fswatch, support OS X/Linux/Windows.

  1.Install fswatch.

  2.Run command in your project root directory.

  # Watch current directory
  ./bin/fswatch
  # Watch app directory
  ./bin/fswatch ./app
  

Get the instance of SwooleServer in your project

/**

$swoole = app('swoole');
var_dump($swoole->stats());// Singleton

Use SwooleTable

1.Define 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 Table: all table instances will be bound on SwooleServer, access by app('swoole')->xxxTable.

use Swoole\Http\Request;
use Swoole\WebSocket\Frame;
use Swoole\WebSocket\Server;
// Scene：bind UserId & FD in WebSocket
public function onOpen(Server $server, 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(Server $server, Frame $frame)
{
    foreach (app('swoole')->wsTable as $key => $row) {
        if (strpos($key, 'uid:') === 0 && $server->exist($row['value'])) {
            $server->push($row['value'], 'Broadcast: ' . date('Y-m-d H:i:s'));// Broadcast
        }
    }
}
public function onClose(Server $server, $fd, $reactorId)
{
    $uid = app('swoole')->wsTable->get('fd:' . $fd);
    if ($uid !== false) {
        app('swoole')->wsTable->del('uid:' . $uid['value']); // Unbind uid map
    }
    app('swoole')->wsTable->del('fd:' . $fd);// Unbind fd map
    $server->push($fd, 'Goodbye');
}

Multi-port mixed protocol

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.

1. Create socket handler class, and extend Hhxsv5\LaravelS\Swoole\Socket\{TcpSocket|UdpSocket|Http|WebSocket}.

   namespace App\Sockets;
   use Hhxsv5\LaravelS\Swoole\Socket\TcpSocket;
   use Swoole\Server;
   class TestTcpSocket extends TcpSocket
   {
       public function onConnect(Server $server, $fd, $reactorId)
       {
           \Log::info('New TCP connection', [$fd]);
           $server->send($fd, 'Welcome to LaravelS.');
       }
       public function onReceive(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(Server $server, $fd, $reactorId)
       {
           \Log::info('Close TCP connection', [$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 SwooleTable, 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(Server $server, $fd, $reactorId, $data)
   {
       $port = $this->swoolePort; //There you go
   }
   

2. Register Sockets.

   // Edit `config/laravels.php`
   //...
   'sockets' => [
       [
           'host'     => '127.0.0.1',
           'port'     => 5291,
           'type'     => SWOOLE_SOCK_TCP,// Socket type: SWOOLE_SOCK_TCP/SWOOLE_SOCK_TCP6/SWOOLE_SOCK_UDP/SWOOLE_SOCK_UDP6/SWOOLE_UNIX_DGRAM/SWOOLE_UNIX_STREAM
           'settings' => [// Swoole settings：https://www.swoole.co.uk/docs/modules/swoole-server-methods#swoole_server-addlistener
               'open_eof_check' => true,
               'package_eof'    => "\r\n",
           ],
           'handler'  => \App\Sockets\TestTcpSocket::class,
       ],
   ],
   

   About the heartbeat configuration, it can only be set on the main server and cannot be configured on Socket, but the Socket inherits the heartbeat configuration of the main server.

   For TCP socket, onConnect and onClose events will be blocked when dispatch_mode of Swoole is 1/3, so if you want to unblock these two events please set dispatch_mode to 2/4/5.

   'swoole' => [
       //...
       'dispatch_mode' => 2,
       //...
   ];
   

3. Test.

• TCP: telnet 127.0.0.1 5291

• UDP: [Linux] echo "Hello LaravelS" > /dev/udp/127.0.0.1/5292

4. Register example of other protocols.

   • UDP

   'sockets' => [
       [
           'host'     => '0.0.0.0',
           'port'     => 5292,
           'type'     => SWOOLE_SOCK_UDP,
           'settings' => [
               'open_eof_check' => true,
               'package_eof'    => "\r\n",
           ],
           'handler'  => \App\Sockets\TestUdpSocket::class,
       ],
   ],
   

   • Http

   'sockets' => [
       [
           'host'     => '0.0.0.0',
           'port'     => 5293,
           'type'     => SWOOLE_SOCK_TCP,
           'settings' => [
               'open_http_protocol' => true,
           ],
           'handler'  => \App\Sockets\TestHttp::class,
       ],
   ],
   

   • WebSocket: The main server must turn on WebSocket, that is, set websocket.enable to true.

   'sockets' => [
       [
           'host'     => '0.0.0.0',
           'port'     => 5294,
           'type'     => SWOOLE_SOCK_TCP,
           'settings' => [
               'open_http_protocol'      => true,
               'open_websocket_protocol' => true,
           ],
           'handler'  => \App\Sockets\TestWebSocket::class,
       ],
   ],
   

Coroutine

Swoole Coroutine

• Warning: There are a large number of singletons and static properties in Laravel/Lumen, which are unsafe in coroutine. It is NOT recommended to enable coroutine, but coroutine can be used in custom processes and cron job.

• Enable Coroutine, default disable.

  // Edit `config/laravels.php`
  [
      //...
      'swoole' => [
          //...
          'enable_coroutine' => true
       ],
  ]
  

• Coroutine Client: require Swoole>=2.0.

• Runtime Coroutine: require Swoole>=4.1.0, and enable it.

  // Edit `config/laravels.php`
  [
      //...
      'enable_coroutine_runtime' => true
      //...
  ]
  

Custom process

Support developers to create special work processes for monitoring, reporting, or other special tasks. Refer addProcess.

1. Create Proccess class, implements CustomProcessInterface.

   namespace App\Processes;
   use App\Tasks\TestTask;
   use Hhxsv5\LaravelS\Swoole\Process\CustomProcessInterface;
   use Hhxsv5\LaravelS\Swoole\Task\Task;
   use Swoole\Coroutine;
   use Swoole\Http\Server;
   use Swoole\Process;
   class TestProcess implements CustomProcessInterface
   {
       public static function getName()
       {
           // The name of process
           return 'test';
       }
       public static function isRedirectStdinStdout()
       {
           // Whether redirect stdin/stdout
           return false;
       }
       public static function getPipeType()
       {
           // The type of pipeline: 0 no pipeline, 1 SOCK_STREAM, 2 SOCK_DGRAM
           return 0;
       }
       public static function callback(Server $swoole, Process $process)
       {
           // The callback method cannot exit. Once exited, Manager process will automatically create the process 
           \Log::info(__METHOD__, [posix_getpid(), $swoole->stats()]);
           while (true) {
               \Log::info('Do something');
               // sleep(1); // Swoole < 2.1
               Coroutine::sleep(1); // Swoole>=2.1 Coroutine will be automatically created for callback().
                // Deliver task in custom process, but NOT support callback finish() of task.
               // Note:
               // 1.Set parameter 2 to true
               // 2.Modify task_ipc_mode to 1 or 2 in config/laravels.php, see https://www.swoole.co.uk/docs/modules/swoole-server/configuration
               $ret = Task::deliver(new TestTask('task data'), true);
               var_dump($ret);
               // The upper layer will capture the exception thrown in the callback and record it to the Swoole log. If the number of exceptions reaches 10, the process will exit and the Manager process will re-create the process. Therefore, developers are encouraged to try/catch to avoid creating the process too frequently.
               // throw new \Exception('an exception');
           }
       }
       // Requirements: LaravelS >= v3.4.0 & callback() must be async non-blocking program.
       public static function onReload(Server $swoole, Process $process)
       {
           // Stop the process...
           // Then end process
           $process->exit(0);
       }
   }
   

2. Register TestProcess.

   // Edit `config/laravels.php`
   // ...
   'processes' => [
       \App\Processes\TestProcess::class,
   ],
   

3. Note: The TestProcess::callback() method cannot quit. If the number of quit reaches 10, the Manager process will re-create the process.

Other features

Configuring the event callback function of Swoole

Supported events:

| Event | Interface | When happened | | -------- | -------- | -------- | | WorkerStart | Hhxsv5\LaravelS\Swoole\Events\WorkerStartInterface | Occurs when the Worker/Task process starts, and the Laravel initialization has been completed. | | WorkerStop | Hhxsv5\LaravelS\Swoole\Events\WorkerStopInterface | Occurs when the Worker/Task process exits normally. | | WorkerError | Hhxsv5\LaravelS\Swoole\Events\WorkerErrorInterface | Occurs when an exception or fatal error occurs in the Worker/Task process. |

1.Create an event class to implement the corresponding interface.

namespace App\Events;
use Hhxsv5\LaravelS\Swoole\Events\WorkerStartInterface;
use Swoole\Http\Server;
class WorkerStartEvent implements WorkerStartInterface
{
    public function __construct()
    {
    }
    public function handle(Server $server, $workerId)
    {
        // Initialize a database connection pool
        // DatabaseConnectionPool::init();
    }
}

2.Configuration.

// Edit `config/laravels.php`
'event_handlers' => [
    'WorkerStart' => \App\Events\WorkerStartEvent::class,
],

Important notices

• 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.

  • If Session/Authentication/JWT is used in your project, please uncomment the cleaners in laravels.php as appropriate.

  • Common solutions:

    1. Write a XxxCleaner class to clean up the singleton object state. This class implements the interface Hhxsv5\LaravelS\Illuminate\Cleaners\CleanerInterface and then registers it in cleaners of laravels.php.

    2. Reset status of singleton instances by Middleware.

    3. Re-register ServiceProvider, add XxxServiceProvider into register_providers of file laravels.php. So that reinitialize singleton instances in ervery request Refer.

• Known issues

• Should get all request information from Illuminate\Http\Request Object, $_ENV is readable, $_SERVER is partially readable, CANNOT USE $_GET/$_POST/$_FILES/$_COOKIE/$_REQUEST/$_SESSION/$GLOBALS.

  public function form(\Illuminate\Http\Request $request)
  {
      $name = $request->input('name');
      $all = $request->all();
      $sessionId = $request->cookie('sessionId');
      $photo = $request->file('photo');
      // Call getContent() to get the raw POST body, instead of file_get_contents('php://input')
      $rawContent = $request->getContent();
      //...
  }
  

• Respond by Illuminate\Http\Response Object, compatible with echo/vardump()/print_r()，CANNOT USE functions dd()/exit()/die()/header()/setcookie()/http_response_code().

  public function json()
  {
      return response()->json(['time' => time()])->header('header1', 'value1')->withCookie('c1', 'v1');
  }
  

• The various singleton connections will be memory resident, recommend to enable persistent connection.

1. Database connection, it will reconnect automatically immediately after disconnect.

   // config/database.php
   //...
   'connections' => [
       'my_conn' => [
           'driver'    => 'mysql',
           'host'      => env('DB_MY_CONN_HOST', 'localhost'),
           'port'      => env('DB_MY_CONN_PORT', 3306),
           'database'  => env('DB_MY_CONN_DATABASE', 'forge'),
           'username'  => env('DB_MY_CONN_USERNAME', 'forge'),
           'password'  => env('DB_MY_CONN_PASSWORD', ''),
           'charset'   => 'utf8mb4',
           'collation' => 'utf8mb4_unicode_ci',
           'prefix'    => '',
           'strict'    => false,
           'options'   => [
               // Enable persistent connection
               \PDO::ATTR_PERSISTENT => true,
           ],
       ],
       //...
   ],
   //...
   

2. Redis connection, it won't reconnect automatically immediately after disconnect, and will throw an exception about lost connection, reconnect next time. You need to make sure that SELECT DB correctly before operating Redis every time.

   // config/database.php
   'redis' => [
           'default' => [
               'host'       => env('REDIS_HOST', 'localhost'),
               'password'   => env('REDIS_PASSWORD', null),
               'port'       => env('REDIS_PORT', 6379),
               'database'   => 0,
               'persistent' => true, // Enable persistent connection
           ],
       ],
   //...
   

• global, static variables which you declared are need to destroy(reset) manually.

• Infinitely appending element into static/global variable will lead to memory leak.

  // Some class
  class Test
  {
      public static $array = [];
      public static $string = '';
  }
  
  // Controller
  public function test(Request $req)
  {
      // Memory leak
      Test::$array[] = $req->input('param1');
      Test::$string .= $req->input('param2');
  }
  

• Linux kernel parameter adjustment

• Pressure test
