其实很简单难的就是后面的路很漫长慢慢琢磨

1.官网下载PHPEXel
下载地址：https://github.com/PHPOffice/PHPExcel
下载后只要Classes，复制Classes到tp5的extend下，并改名为PHPExcel，如下图所示

2.直接使用
建立Excel控制器，如下图所示，内容如下所示（例如：我要导出admin表中的内容，代码如下），导出如下图二所示。

代码如下：

<?php

namespace app\index\controller;
use think\Controller;
class Excel extends Controller
{
    public function outExcelRecharge() {

        $data       = db('admin')->order('id desc')->select();

        $field = array(
            'A' => array('id', '唯一标识符'),
            'B' => array('username', '账号'),
            'C' => array('name', '姓名'),
            'D' => array('phone', '电话'),
            'E' => array('time', '注册时间'),
        );
        $this->phpExcelList($field, $data, '后台用户_' . date('Y-m-d'));
    }

    /**
     * 直接导出需要生产的内容
     * @param $field
     * @param $list
     * @param string $title
     * @throws \PHPExcel_Exception
     * @throws \PHPExcel_Writer_Exception
     */
    public function phpExcelList($field, $list, $title='文件')
    {
        import('PHPExcel.PHPExcel');
        $objPHPExcel = new \PHPExcel();
        $objWriter = new \PHPExcel_Writer_Excel5($objPHPExcel); //设置保存版本格式
        foreach ($list as $key => $value) {
            foreach ($field as $k => $v) {
                if ($key == 0) {
                    $objPHPExcel->getActiveSheet()->setCellValue($k . '1', $v[1]);
                }
                $i = $key + 2; //表格是从2开始的
                $objPHPExcel->getActiveSheet()->setCellValue($k . $i, $value[$v[0]]);
            }
        }
        header("Pragma: public");
        header("Expires: 0");
        header("Cache-Control:must-revalidate, post-check=0, pre-check=0");
        header("Content-Type:application/force-download");
        header("Content-Type:application/vnd.ms-execl");
        header("Content-Type:application/octet-stream");
        header("Content-Type:application/download");;
        header('Content-Disposition:attachment;filename='.$title.'.xls');
        header("Content-Transfer-Encoding:binary");
        $objWriter->save('php://output');
    }

}

效果如下：
