Channel Distributed Communication Component

(Requires Workerman version >= 3.3.0)

Source code: https://github.com/walkor/Channel

Channel is a distributed communication component designed for inter-process or inter-server communication.

Features

1. Based on the publish-subscribe model

2. Non-blocking IO

Principles

Channel consists of Channel/Server (server side) and Channel/Client (client side).

Channel/Client connects to Channel/Server via the connect interface and maintains a long connection.

Channel/Client uses the on interface to inform Channel/Server about which events it is interested in and registers event callback functions (the callbacks occur in the process where Channel/Client is located).

Channel/Client publishes an event and related data to Channel/Server through the publish interface.

Upon receiving the event and data, Channel/Server will distribute it to Channel/Clients that are interested in the event.

Channel/Client triggers the callback set by the on interface upon receiving the event and data.

Channel/Client will only receive events it is interested in and trigger the corresponding callbacks.

Installation

composer require workerman/channel

Note

Channel can only be used in the Workerman environment and cannot be used in a php-fpm environment.
