## What is it
Workerman is an asynchronous event-driven PHP framework with high performance to build fast and scalable network applications. 
Workerman supports HTTP, Websocket, SSL and other custom protocols. 
Workerman supports event extension.

## Requires
PHP 5.3 or Higher  
A POSIX compatible operating system (Linux, OSX, BSD)  
POSIX and PCNTL extensions required   
Event extension recommended for better performance

## Installation

```
composer require workerman/workerman
```

## Basic Usage

### A websocket server 
```php
<?php

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

// Create a Websocket server
$ws_worker = new Worker('websocket://0.0.0.0:2346');

// Emitted when new connection come
$ws_worker->onConnect = function ($connection) {
    echo "New connection\n";
};

// Emitted when data received
$ws_worker->onMessage = function ($connection, $data) {
    // Send hello $data
    $connection->send('Hello ' . $data);
};

// Emitted when connection closed
$ws_worker->onClose = function ($connection) {
    echo "Connection closed\n";
};

// Run worker
Worker::runAll();
```

### An http server
```php
use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

// #### http worker ####
$http_worker = new Worker('http://0.0.0.0:2345');

// 4 processes
$http_worker->count = 4;

// Emitted when data received
$http_worker->onMessage = function ($connection, $request) {
    //$request->get();
    //$request->post();
    //$request->header();
    //$request->cookie();
    //$request->session();
    //$request->uri();
    //$request->path();
    //$request->method();

// Send data to client
    $connection->send("Hello World");
};

// Run all workers
Worker::runAll();
```

### A tcp server
```php
use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

// #### create socket and listen 1234 port ####
$tcp_worker = new Worker('tcp://0.0.0.0:1234');

// 4 processes
$tcp_worker->count = 4;

// Emitted when new connection come
$tcp_worker->onConnect = function ($connection) {
    echo "New Connection\n";
};

// Emitted when data received
$tcp_worker->onMessage = function ($connection, $data) {
    // Send data to client
    $connection->send("Hello $data \n");
};

// Emitted when connection is closed
$tcp_worker->onClose = function ($connection) {
    echo "Connection closed\n";
};

Worker::runAll();
```

### Enable SSL
```php
<?php

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

// SSL context.
$context = array(
    'ssl' => array(
        'local_cert'  => '/your/path/of/server.pem',
        'local_pk'    => '/your/path/of/server.key',
        'verify_peer' => false,
    )
);

// Create a Websocket server with ssl context.
$ws_worker = new Worker('websocket://0.0.0.0:2346', $context);

// Enable SSL. WebSocket+SSL means that Secure WebSocket (wss://). 
// The similar approaches for Https etc.
$ws_worker->transport = 'ssl';

$ws_worker->onMessage = function ($connection, $data) {
    // Send hello $data
    $connection->send('Hello ' . $data);
};

Worker::runAll();
```

### Custom protocol
Protocols/MyTextProtocol.php
```php

namespace Protocols;

/**
 * User defined protocol
 * Format Text+"\n"
 */
class MyTextProtocol
{
    public static function input($recv_buffer)
    {
        // Find the position of the first occurrence of "\n"
        $pos = strpos($recv_buffer, "\n");

// Not a complete package. Return 0 because the length of package can not be calculated
        if ($pos === false) {
            return 0;
        }

// Return length of the package
        return $pos+1;
    }

public static function decode($recv_buffer)
    {
        return trim($recv_buffer);
    }

public static function encode($data)
    {
        return $data . "\n";
    }
}
```

```php
use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

// #### MyTextProtocol worker ####
$text_worker = new Worker('MyTextProtocol://0.0.0.0:5678');

$text_worker->onConnect = function ($connection) {
    echo "New connection\n";
};

$text_worker->onMessage = function ($connection, $data) {
    // Send data to client
    $connection->send("Hello world\n");
};

$text_worker->onClose = function ($connection) {
    echo "Connection closed\n";
};

// Run all workers
Worker::runAll();
```

### Timer
```php

use Workerman\Worker;
use Workerman\Timer;

require_once __DIR__ . '/vendor/autoload.php';

$task = new Worker();
$task->onWorkerStart = function ($task) {
    // 2.5 seconds
    $time_interval = 2.5; 
    $timer_id = Timer::add($time_interval, function () {
        echo "Timer run\n";
    });
};

// Run all workers
Worker::runAll();
```

### AsyncTcpConnection (tcp/ws/text/frame etc...)
```php

use Workerman\Worker;
use Workerman\Connection\AsyncTcpConnection;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker();
$worker->onWorkerStart = function () {
    // Websocket protocol for client.
    $ws_connection = new AsyncTcpConnection('ws://echo.websocket.org:80');
    $ws_connection->onConnect = function ($connection) {
        $connection->send('Hello');
    };
    $ws_connection->onMessage = function ($connection, $data) {
        echo "Recv: $data\n";
    };
    $ws_connection->onError = function ($connection, $code, $msg) {
        echo "Error: $msg\n";
    };
    $ws_connection->onClose = function ($connection) {
        echo "Connection closed\n";
    };
    $ws_connection->connect();
};

Worker::runAll();
```
