使用phpoffice/phpspreadsheet，导入导出数据

1、composer安装：

composer require phpoffice/phpspreadsheet



2、导出类Export，放在服务层：

<?php

namespace app\backend\service;

use \PhpOffice\PhpSpreadsheet\Spreadsheet;

use \PhpOffice\PhpSpreadsheet\IOFactory; //use \PHPExcel_Style_NumberFormat;    //设置列的格式==>>设置文本格式



class Export

{

    public function exportAdmin($startTime, $endTime)

    {

        $adminList = db('admin')

            ->where('create_time', 'between', [$startTime, $endTime])

            ->order(['admin_id' => 'desc'])

            ->select();

        //return $adminList;



        $newExcel = new Spreadsheet();  //创建一个新的excel文档

        $objSheet = $newExcel->getActiveSheet();  //获取当前操作sheet的对象

        $objSheet->setTitle('管理员表');  //设置当前sheet的标题



        //设置宽度为true,不然太窄了

        $newExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);

        $newExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);

        $newExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);

        $newExcel->getActiveSheet()->getColumnDimension('D')->setAutoSize(true);



        //设置第一栏的标题

        $objSheet->setCellValue('A1', 'id')

            ->setCellValue('B1', '用户名')

            ->setCellValue('C1', '密码')

            ->setCellValue('D1', '时间');



        //第二行起，每一行的值,setCellValueExplicit是用来导出文本格式的。

        //->setCellValueExplicit('C' . $k, $val['admin_password']PHPExcel_Cell_DataType::TYPE_STRING),可以用来导出数字不变格式

        foreach ($adminList as $k => $val) {

            $k = $k + 2;

            $objSheet->setCellValue('A' . $k, $val['admin_id'])

                ->setCellValue('B' . $k, $val['admin_username'])

                ->setCellValue('C' . $k, $val['admin_password'])

                ->setCellValue('D' . $k, date('Y-m-d H:i:s', $val['create_time']));

        }



        $this->downloadExcel($newExcel, '管理员表', 'Xls');

    }



    //公共文件，用来传入xls并下载

    function downloadExcel($newExcel, $filename, $format)

    {

        // $format只能为 Xlsx 或 Xls

        if ($format == 'Xlsx') {

            header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');

        } elseif ($format == 'Xls') {

            header('Content-Type: application/vnd.ms-excel');

        }



        header("Content-Disposition: attachment;filename=". $filename . date('Y-m-d') . '.' . strtolower($format));

        header('Cache-Control: max-age=0');

        $objWriter = IOFactory::createWriter($newExcel, $format);



        $objWriter->save('php://output');



        //通过php保存在本地的时候需要用到

        //$objWriter->save($dir.'/demo.xlsx');



        //以下为需要用到IE时候设置

        // If you're serving to IE 9, then the following may be needed

        //header('Cache-Control: max-age=1');

        // If you're serving to IE over SSL, then the following may be needed

        //header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past

        //header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified

        //header('Cache-Control: cache, must-revalidate'); // HTTP/1.1

        //header('Pragma: public'); // HTTP/1.0

        exit;

    }

}



3、导入类Import，放在服务层：

<?php

namespace app\backend\service;

use think\Controller;

use \PhpOffice\PhpSpreadsheet\IOFactory;



class Import extends Controller

{

    public function importAdmin()

    {

        //获取表格的大小，限制上传表格的大小5M

        $file_size = $_FILES['myfile']['size'];

        if ($file_size > 5 * 1024 * 1024) {

            $this->error('文件大小不能超过5M');

            exit();

        }



        //限制上传表格类型

        $fileExtendName = substr(strrchr($_FILES['myfile']["name"], '.'), 1);

        //application/vnd.ms-excel  为xls文件类型

        if ($fileExtendName != 'xls') {

            $this->error('必须为excel表格，且必须为xls格式！');

            exit();

        }



        if (is_uploaded_file($_FILES['myfile']['tmp_name'])) {

            // 有Xls和Xlsx格式两种

            $objReader = IOFactory::createReader('Xls');



            $filename = $_FILES['myfile']['tmp_name'];

            $objPHPExcel = $objReader->load($filename);  //$filename可以是上传的表格，或者是指定的表格

            $sheet = $objPHPExcel->getSheet(0);   //excel中的第一张sheet

            $highestRow = $sheet->getHighestRow();       // 取得总行数

            // $highestColumn = $sheet->getHighestColumn();   // 取得总列数



            //定义$usersExits，循环表格的时候，找出已存在的用户。

            $usersExits = [];

            //循环读取excel表格，整合成数组。如果是不指定key的二维，就用$data[i][j]表示。

            for ($j = 2; $j <= $highestRow; $j++) {

                $data[$j - 2] = [

                    'admin_username' => $objPHPExcel->getActiveSheet()->getCell("A" . $j)->getValue(),

                    'admin_password' => $objPHPExcel->getActiveSheet()->getCell("B" . $j)->getValue(),

                    'create_time' => time()

                ];

                //看下用户名是否存在。将存在的用户名保存在数组里。

                $userExist = db('admin')->where('admin_username', $data[$j - 2]['admin_username'])->find();

                if ($userExist) {

                    array_push($usersExits, $data[$j - 2]['admin_username']);

                }

            }

            //halt($usersExits);



            //如果有已存在的用户名，就不插入数据库了。

            if ($usersExits != []) {

                //把数组变成字符串，向前端输出。

                $c = implode(" / ", $usersExits);

                $this->error('Excel中以下用户名已存在:' . $c, "/backend/admin/create", '', 20);

                exit();

            }



            //halt($data);

            //插入数据库

            $res = db('admin')->insertAll($data);

            if ($res) {

                $this->success('上传成功！', '/backend/admin', '', 1);

            }

        }

    }

}

4、导出类Export，放在服务层：

/**

* [importoptions 读取数据]

*/

public function importoptions()

{

      if($this->request->isPost()){

      //获取参数

            $params = $this->request->param();



            $inputFileName = '';

            //上传文件

            $file = request()->file('file');

            $info = $file->validate(['ext' => 'xls,xlsx'])->move('./uploads/xslx/');

            if($info){

            // 成功上传后 获取上传信息

                  $inputFileName =  './uploads/xslx/' . $info->getSaveName();

             } else {

                $this->error('文件上传失败：'.$file->getError());

            }



          //验证文件

          if(!file_exists($inputFileName)){

                $this->error('文件异常');

          }



          //获取excel文件

          $inputFileType = \PhpOffice\PhpSpreadsheet\IOFactory::identify($inputFileName);

          $reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader($inputFileType);

          $spreadsheet = $reader->load($inputFileName);

         $data = $spreadsheet->getActiveSheet()->toArray();

         if(!empty($data)){

            unset($data[0]);

         }



        //获取所有题目编号

        $number = \Db::name('wechat_guess_options')->column('number');

        $add_data = [];

        if(!empty($data)){

             foreach ($data as $key => $value) {

                 if(in_array($value[0], $number)){

                     continue;

                  }

                   //去除重复编号记录

                 $add_data[$key]['number'] = $value[0];

                 $add_data[$key]['name']   = $value[1];

       }



     //重新索引

     $add_data = array_values($add_data);

     if(empty($add_data)){

     $this->error('导入数据已经存在');

  }



   //写入数据

  $res = \Db::name('wechat_guess_options')->insertAll($add_data);

  if($res){

      $this->success('导入成功');

  } else {

      $this->error('导入失败');

   }

 }

}



5、导出类Export，放在服务层：

public function exportSignup()

      //查询数据

      $data = $this->model_signup->field('id,name,mobile,address,ip,create_time,thumb')->order('create_time desc')->select();
