下面由workerman php教程栏目给大家介绍workerman结合laravel开发在线聊天应用的方法，希望对需要的朋友有所帮助！

workerman combines laravel to develop online chat application

项目背景：

最近由于公司的业务需求，需要用到聊天功能。而且有比较多的个性化需求需要定制。之前使用别人的聊天组件是基于微擎的。如果要移植到普通的H5在逻辑修改还有定制上存在比较多的困难。为此只能克服困难，自己搭建一个吧

什么是Workerman？

Workerman是一款开源高性能异步PHP socket即时通讯框架。支持高并发，超高稳定性，被广泛的用于手机app、移动通讯，微信小程序，手游服务端、网络游戏、PHP聊天室、硬件通讯、智能家居、车联网、物联网等领域的开发。 

支持TCP长连接，支持Websocket、HTTP等协议，支持自定义协议。拥有异步Mysql、异步Redis、异步Http、MQTT物联网客户端、异步消息队列等众多高性能组件。

开始实战吧！

1.第一步我们先把workerman里需要用到的扩展composer下来吧

"workerman/gateway-worker": "^3.0",
"workerman/gatewayclient": "^3.0",
"workerman/workerman": "^3.5",

2.第二步我们到官方网站把demo全部下载下来，然后放到我们项目中的目录图片中我就把整个项目都放在了HTTP/Controller/Workerman中。

3.第三步我们需要把把以下3个文件的引用部分修改为以下。

不然会报路径错误

start_businessworker，start_gateway，start_register
require_once __DIR__ . '/../../../../../vendor/autoload.php';

4.修改完成后我们就可以在liunx直接运行对应的启动文件

php start.php start -d
如果你是在window下就双击start_for_win.bat运行

5.运行成功后，你就应该可以看到以下的界面到此我们搭建基于workerman的通信环境就已经完成。

接下来我们就可以根据自己的项目需求进行开发。

在此向大家重点说明。

我们所有的聊天是逻辑都在目录中的Events.php进行修改。

下面我给大家贴一下我编写的部分代码。

Event.php
