Uma implementação alternativa de socket.io no lado do servidor em PHP baseada em Workerman.

Perceber

Suporta apenas socket.io >= v1.3.0 e <= v2.x
Este projeto é apenas traduzido de socket.io por trabalhador.

Exemplos

Bate-papo simples

iniciar.php

 use Workerman  Worker ;
use PHPSocketIO  SocketIO ;
require_once __DIR__ . ' /vendor/autoload.php ' ;

// Listen port 2021 for socket . io client
$ io = new SocketIO ( 2021 );
$ io -> on ( ' connection ' , function ( $ socket ) use ( $ io ) {
    $ socket -> on ( ' chat message ' , function ( $ msg ) use ( $ io ) {
        $ io -> emit ( ' chat message ' , $ msg );
    });
});
