<?php
use Workerman\Worker;
use Workerman\Redis\Client;
use Workerman\Connection\TcpConnection;
use Workerman\Timer;
require_once __DIR__ . '/vendor/autoload.php';
 
$worker = new Worker('http://0.0.0.0:6161');
global  $offset;
$worker->onWorkerStart = function() {
    global  $offset;
    $offset=0;
};
 
$worker->onMessage = function(TcpConnection $connection, $data) {
    $redis = new Client('redis://127.0.0.1:6379');
    $redis->del(["key1","key2","key3"],function($res) use($redis){
        var_dump("del:");
        var_dump($res);
 
        $redis->sAdd('key1' , ['member1','member2','member3','member4','member5'],function($res) use($redis){
                var_dump("sAdd1:");
                var_dump($res);
 
                $redis->sAdd('key2' , ['member6','member7','member8','member9','member10'],function($res) use($redis){
                    var_dump("sAdd2:");
                    var_dump($res);
 
 
                    $redis->sAdd('key3' , ['member11','member12','member13','member14','member15'],function($res) use($redis){
                        var_dump("sAdd3:");
                        var_dump($res);
 
                        $redis->sUnion(['key1', 'key2', 'key3'], function ($r) {
                            var_dump("sUnion:");
                            var_dump($r);
                        });
 
                    });
