使用PHPExcel将数据导出至Excel

安装类库

从GitHub上下载PHPExcel类库
地址：https://github.com/PHPOffice/PHPExcel

解压后将Classes文件夹移动到ThinkPHP的extend目录，并将其重命名为phpexcel

在项目中需要的地方添加引用

import(\'phpexcel.PHPExcel\', EXTEND_PATH);

代码实现

<?php
namespace app\index\controller;

use think\Controller;

class Excel extends Controller
{
    // 将数据导出至Excel
    public function exportExcel()
    {
        // 引入类库
        import(\'phpexcel.PHPExcel\', EXTEND_PATH);

        // 文件名和文件类型
        $fileName = "student";
        $fileType = "xlsx";

        // 模拟获取数据
        $data = self::getData();

        $obj = new \PHPExcel();

        // 以下内容是excel文件的信息描述信息
        $obj->getProperties()->setCreator(\'\'); //设置创建者
        $obj->getProperties()->setLastModifiedBy(\'\'); //设置修改者
        $obj->getProperties()->setTitle(\'\'); //设置标题
        $obj->getProperties()->setSubject(\'\'); //设置主题
        $obj->getProperties()->setDescription(\'\'); //设置描述
        $obj->getProperties()->setKeywords(\'\');//设置关键词

        // 设置当前sheet

            }
        }

        return $studentList;

运行

浏览器访问http://127.0.0.1:8083/index/excel/exportExcel下载Excel文件

打开文件如下:

可以看到Excel中的数据和PHP数组中的数据是一致的！
