php实现微信公众号无限群发

利用微信客服接口进行各类消息的无限群发

sendAllMsg.php

<?php
 /*
 Author:yf
 使用说明:微信公众号无限群发接口，使用实例: 
 $test = new SendAllMsg("你的appId","你的appSecret");
 $test->sendMsgToAll(); //调用群发方法
 注：1.使用条件：认证号或测试号
 2.群发消息内容可为图文、文本、音乐等,$data具体内容参照微信开发文档/客服接口
 3.若用户量过万,需修改getUserInfo()，具体参照信开发文档/获取关注者列表
 
 新手上路，大神们多多指点，谢谢
