【PHP】使用phpoffice/phpspreadsheet导入导出数据

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

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

composer require phpoffice/phpspreadsheet

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

 //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(

                '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'])
