可以试试textalk/websocket这个开源库

composer require textalk/websocket；

github：https://github.com/Textalk/websocket-php

使用方式

1、websocket服务端

$server = new WebSocket\Server();
$server->accept();
$message = $server->receive();
$server->text($message);
$server->close();

2、websocket客户端

$client = new WebSocket\Client("ws://echo.websocket.org/");
$client->text("Hello WebSocket.org!");
echo $client->receive();
$client->close();
