TP6导入、导出Excel教程

当你在使用 phpoffice/phpexcel 类库时候。composer 会给你提示一句话：

• Package phpoffice/phpexcel is abandoned, you should avoid using it. Use phpoffice/phpspreadsheet instead

中文翻译

• 软件包 phpoffice/phpexcel 被放弃了，您应该避免使用它。 使用 phpoffice/phpspreadsheet 代替phpexcel已被废弃，建议我们用phpspreadsheet。

下面就给大家说说“phpoffice/phpspreadsheet导入导出数据”教程：

包地址：

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

Composer安装：

composer require phpoffice/phpspreadsheet

引入：

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

导出：

//execl模板下载
public function template_download()
    {
        $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('导入模板');  //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);

        //设置第一栏的标题
        $objSheet->setCellValue('A1', '用户id')
            ->setCellValue('B1', '昵称')
            ->setCellValue('C1', '手机号');

        //默认数据
        $explame_data_list = array(
            array(
                'user_id' => '1',
                'nickname' => '小明',
                'phone' => '15012345678',
            ),
        );

        //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
        $baseRow = 2; //数据从N-1行开始往下输出 这里是避免头信息被覆盖
        foreach ($explame_data_list as $k => $val) {
            $i = $k + $baseRow;
            $objSheet->setCellValue('A' . $i, $val['user_id'])
                ->setCellValue('B' . $i, $val['nickname'])
                ->setCellValue('C' . $i, $val['phone']);
        }

        $this->downloadExcel($newExcel, '会员批量导入模板', 'Xls');
    }

//公共文件，用来传入xls并下载
private 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;
    }

导入：

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