【PHP】使用phpoffice/phpexcel导入导出数据

本例以thinkphp5.1为例

包地址：

https://packagist.org/packages/phpoffice/phpexcel

使用：

composer require phpoffice/phpexcel

控制器引入

//引入phpoffice
use PHPExcel;
use PHPExcel_IOFactory;

 

导出代码：

//execl模板下载
    public function template_download()
    {
        $objExcel = new PHPExcel();
        $objWriter = \PHPExcel_IOFactory::createWriter($objExcel, \'Excel5\');
        $objActSheet = $objExcel->getActiveSheet(0);
        $objActSheet->setTitle(\'会员批量导入模板\'); //设置excel的标题
        $objActSheet->setCellValue(\'A1\', \'用户id\');
        $objActSheet->setCellValue(\'B1\', \'昵称\');
        $objActSheet->setCellValue(\'C1\', \'手机号\');

        $baseRow = 2; //数据从N-1行开始往下输出 这里是避免头信息被覆盖
        //默认数据
        $explame_data = array(
            array(
                \'user_id\' => \'1\',
                \'nickname\' => \'小明\',
                \'phone\' => \'15012345678\',
            ),
        );

        foreach ($explame_data as $key => $value) {
            $i = $baseRow + $key;
            $objExcel->getActiveSheet()->setCellValue(\'A\' . $i, $value[\'user_id\']);
            $objExcel->getActiveSheet()->setCellValue(\'B\' . $i, $value[\'nickname\']);
            $objExcel->getActiveSheet()->setCellValue(\'C\' . $i, $value[\'phone\']);
        }


        $objExcel->setActiveSheetIndex(0);
        //4、输出
        $objExcel->setActiveSheetIndex();
        header(\'Content-Type: applicationnd.ms-excel\');
        $time = date(\'Y-m-d\');
        header("Content-Disposition: attachment;filename=会员批量导入模板" . $time . ".xls");
        header(\'Cache-Control: max-age=0\');
        $objWriter->save(\'php://output\');
    }

 

导入代码：

    public function import_batch_send()
    {
        header("content-type:text/html;charset=utf-8");

        //上传excel文件
        $file = request()->file(\'file\');
        //将文件保存到public/uploads目录下面
        $info = $file->validate([\'size\' => 1048576, \'ext\' => \'xls,xlsx\'])->move(\'./uploads\');
        if ($info) {
            //获取上传到后台的文件名
            $fileName = $info->getSaveName();
            //获取文件路径
            $filePath = Env::get(\'root_path\') . \'public\' . DIRECTORY_SEPARATOR . \'uploads\' . DIRECTORY_SEPARATOR . $fileName;
            //获取文件后缀
            $suffix = $info->getExtension();
            //判断哪种类型
            if ($suffix == "xlsx") {
                $reader = \PHPExcel_IOFactory::createReader(\'Excel2007\');
            } else {
                $reader = PHPExcel_IOFactory::createReader(\'Excel5\');
            }
        } else {
            return json([\'status\' => \'1\', \'message\' => \'文件过大或格式不正确导致上传失败-_-!\']);
        }
        //载入excel文件
        $excel = $reader->load($filePath, $encode = \'utf-8\');
        //读取第一张表
        $sheet = $excel->getSheet(0);
        //获取总行数
        $row_num = $sheet->getHighestRow();
        //获取总列数
        $col_num = $sheet->getHighestColumn();

        $import_data = []; //数组形式获取表格数据
        for ($i = 2; $i <= $row_num; $i++) {

            $import_data[$i][\'nickname\']  = $sheet->getCell("B" . $i)->getValue();
            $import_data[$i][\'phone\']  = $sheet->getCell("C" . $i)->getValue();
        }

        if (empty($import_data)) {
            return json([\'status\' => \'1\', \'message\' => \'数据解析失败\']);
        }

        //校验手机号是否重复
        $phone_array = array_column($import_data, \'phone\');
        $phone_ids = implode(\',\', $phone_array);
        $result_phone = db(\'user\')
            ->field(\'phone\')
            ->where(\'phone\', \'in\', $phone_ids)
            ->select();
        if (!empty($result_phone)) {
            $result_phone_array = array_column($result_phone, \'phone\');
            $result_phone_ids = implode(\',\', $result_phone_array);
            return json([\'status\' => \'3\', \'message\' => \'数据重复\', \'result\' => $result_phone_ids]);
        }

        //将数据保存到数据库
        $res = db(\'user\')->insertAll($import_data);
        if ($res) {
            return json([\'status\' => \'2\', \'message\' => \'导入成功\']);
        } else {
            return json([\'status\' => \'1\', \'message\' => \'提交失败，请刷新重试\']);
        }
    }
