本文实例讲述了thinkphp5.0框架结合swoole开发实现websocket在线聊天案例。分享给大家供大家参考,具体如下:
thinkphp使用swoole需要安装 think-swoole composer包,前提系统已经安装好了swoole pecl 拓展(相关文章:linux下源码包安装使用swoole扩展)
在tp5的项目根目录下执行composer命令安装think-swoole:
1
|
composer require topthink/think-swoole
|
安装成功:
话不多说,直接上代码:
新建websocket.php控制器:
(监听端口要确认服务器放行,宝塔环境还需要添加安全组规则)

服务器移到项目根目录开启服务:
1
|
php public /index.php websocket/start
|
(这里的路径,是因为我绑定了home模块为默认模块,tp5默认情况是:php public/index.php index/websocket/start
)
开启成功,查看端口已经被监听:
1
|
lsof -i:9501
|
演示效果如下:
服务器监听如下:
用户每刷新重连一次,fd标识都会改变。
希望本文所述对大家基于thinkphp框架的php程序设计有所帮助。
