+# Channel
+基于订阅的多进程通讯组件，用于workerman进程间通讯或者服务器集群通讯，类似redis订阅发布机制。基于workerman开发。
+
+Channel 提供两种通讯形式，分别是发布订阅的事件机制和消息队列机制。
+
+它们的主要区别是：
+- 事件机制是消息发出后，所有订阅该事件的客户端都能收到消息。
+- 消息队列机制是消息发出后，所有订阅该消息的客户端只有一个会收到消息，如果客户端忙消息会进行排队直到有客户端闲置后重新取到消息。
+- 需要注意的是 Channel 只是提供一种通讯方式，本身并不提供消息确认、重试、延迟、持久化等功能，请根据实际情况合理使用。
+
+# 手册地址
+[Channel手册](http://doc.workerman.net/components/channel.html)
+
+# 服务端
+```php
+use Workerman\Worker;
+
+//Tcp 通讯方式
+$channel_server = new Channel\Server('0.0.0.0', 2206);
+
+//Unix Domain Socket 通讯方式
+//$channel_server = new Channel\Server('unix:///tmp/workerman-channel.sock');
+
+if(!defined('GLOBAL_START'))
+{
+    Worker::runAll();
+}
+```
+
+# 客户端
+```php
+use Workerman\Worker;
+
+$worker = new Worker();
+$worker->onWorkerStart = function()
+{
+    // Channel客户端连接到Channel服务端
+    Channel\Client::connect('<Channel服务端ip>', 2206);
+
+    // 使用 Unix Domain Socket 通讯
+    //Channel\Client::connect('unix:///tmp/workerman-channel.sock');
+
+    // 要订阅的事件名称（名称可以为任意的数字和字符串组合）
+    $event_name = 'event_xxxx';
+    // 订阅某个自定义事件并注册回调，收到事件后会自动触发此回调
+    Channel\Client::on($event_name, function($event_data){
+        var_dump($event_data);
+    });
+};
+$worker->onMessage = function($connection, $data)
+{
+    // 要发布的事件名称
+    $event_name = 'event_xxxx';
+    // 事件数据（数据格式可以为数字、字符串、数组），会传递给客户端回调函数作为参数
+    $event_data = array('some data.', 'some data..');
+    // 发布某个自定义事件，订阅这个事件的客户端会收到事件数据，并触发客户端对应的事件回调
+    Channel\Client::publish($event_name, $event_data);
+};

+# phpsocket.io
+A server side alternative implementation of [socket.io](https://github.com/socketio/socket.io) in PHP based on [Workerman](https://github.com/walkor/Workerman).<br>
+
+# Notice
+Only support socket.io >= v1.3.0 and <= v2.x <br>
+This project is just translate socket.io by [workerman](https://github.com/walkor/Workerman).<br>
+More api just see [https://socket.io/docs/v2/server-api/](https://socket.io/docs/v2/server-api/)

+
+## 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 7.0 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 ($connection) {
+    echo "Connection closed\n";
+};
+
+// Run worker
+Worker::runAll();
+```
+
+### An http server
+```php
+<?php
+
+use Workerman\Worker;
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+// #### http worker ####
+$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();
+```
