    使用說明:微信公眾號無限群發(fā)接口，使用實例:   
    $test = new SendAllMsg("你的appId","你的appSecret");
    $test->sendMsgToAll(); //調(diào)用群發(fā)方法
    注：1.使用條件：認證號或測試號
      2.群發(fā)消息內(nèi)容可為圖文、文本、音樂等,$data具體內(nèi)容參照微信開發(fā)文檔/客服接口
      3.若用戶量過萬,需修改getUserInfo()，具體參照信開發(fā)文檔/獲取關(guān)注者列表
       
    新手上路，大神們多多指點，謝謝
