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
