thinkphp5.0数据导出excel表格

第一步、创建Model类文件（名称自定）

第二步、在类中写入以下代码

<?php

namespace Admin\admin\model;

use think\Model;

class MarkModel extends Model{

    //导出预约信息
    public function outExcel1(){

        $del=@implode(",",$_POST["del"]);

        if($del!=""){

            $art = db('messga');

            $where['id'] = array('in',$del);

            $rs = $art->where($where)->order('id desc')->select();

            foreach ($rs as $v){
                $excdata[]=array(

                    'id'=>$v["id"],

                    'names'=>$v["names"],

                    'phone'=>$v["phone"],

        }else{

                );
            }

            //echo "<script>alert ('请选中要导出的数据'); history.go(-1);</script>";
