workerman推送

服务端代码

<?php
    //websocket服务器
    //问题：
    //1.消息发送，收件方可以有多人
    //2.没有在线的发送不了，上线后发送
    //3.发送失败,返回信息
    //1.设置名称和得到当前没有接收的信息:'{"name":"index","operation":"setget"}';
    //2.发送信息,to为数组'{"from":"index","to":{"0":"shijie","1":"ninini"},"info":"xxxxxxxx","operation":"sendinfo"}';
    //基本思路:当连接完成时后，客户端发送数据，将自己链接重新命名，并查看redis中是否有自己未接收的信息，如果有就返回，每个链接重新命名后都是唯一的，当发送信息时，查看是否有当前客户端是否有链接，如果有链接就发送过去，并将status值改为ok，没有发送则为no，将二维数组存入redis中
