# Workerman
[![Gitter](https://badges.gitter.im/walkor/Workerman.svg)](https://gitter.im/walkor/Workerman?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=body_badge)
## What is it
Workerman is a library for event-driven programming in PHP. It has a huge number of features. Each worker is able to handle thousands of connections.
## Requires
PHP 5.3 or Higher
A POSIX compatible operating system (Linux, OSX, BSD)
POSIX and PCNTL extensions for PHP
## Installation
```
composer require workerman/workerman
```
## Basic Usage
### A websocket server
test.php
```php
<?php
use Workerman\Worker;
require_once './Workerman/Autoloader.php';
// Create a Websocket server
$ws_worker = new Worker("websocket://0.0.0.0:2346");
// 4 processes
$ws_worker->count = 4;
// 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
test.php
```php
require_once './Workerman/Autoloader.php';
use Workerman\Worker;
// #### 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, $data)
{
// $_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES are available
var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);
// send data to client
$connection->send("hello world \n");
};
// run all workers
Worker::runAll();
```
### A WebServer
test.php
```php
require_once './Workerman/Autoloader.php';
use Workerman\WebServer;
use Workerman\Worker;
// WebServer
$web = new WebServer("http://0.0.0.0:80");
// 4 processes
$web->count = 4;
// Set the root of domains
$web->addRoot('www.your_domain.com', '/your/path/Web');
$web->addRoot('www.another_domain.com', '/another/path/Web');
// run all workers
Worker::runAll();
```
### A tcp server
test.php
```php
require_once './Workerman/Autoloader.php';
use Workerman\Worker;
// #### 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 new connection come
$tcp_worker->onClose = function($connection)
{
echo "Connection closed\n";
};
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";
}
}
```
test.php
```php
require_once './Workerman/Autoloader.php';
use Workerman\Worker;
// #### 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
test.php
```php
require_once './Workerman/Autoloader.php';
use Workerman\Worker;
use Workerman\Lib\Timer;
$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();
```
run with:
```php test.php start```
## Available commands
```php test.php start ```
```php test.php start -d ```
![workerman start](http://www.workerman.net/img/workerman-start.png)
```php test.php status ```
![workerman satus](http://www.workerman.net/img/workerman-status.png?a=123)
```php test.php stop ```
```php test.php restart ```
```php test.php reload ```
