php封装excel下载类，使用phpspreadsheet

1、下载composer包

在composer.json的require中加入，引入包文件

"phpoffice/phpspreadsheet": "^1.3",

2、封装类文件到项目中

   '反馈' . date('His') . '.xlsx','columnName' => $columnNames,'columnData' => $columnData];
     */
    public static function exportData($rowList=[])
    {

//        var_dump($rowList);die;

        set_time_limit(0);
        // Create new Spreadsheet object
        $spreadsheet = new Spreadsheet();

        // Set document properties
        $spreadsheet->getProperties()->setCreator('Maarten Balliauw')
            ->setLastModifiedBy('Maarten Balliauw')
            ->setTitle('Office 2007 XLSX Test Document')
            ->setSubject('Office 2007 XLSX Test Document')
            ->setDescription('Test document for Office 2007 XLSX, generated using PHP classes.')
            ->setKeywords('office 2007 openxml php')
            ->setCategory('Test result file');

        //
//        $spreadsheet->setActiveSheetIndex(0);
        $activeSheet = $spreadsheet->setActiveSheetIndex(0);
        foreach ($rowList['columnName'] as $key => $value)
        {
            $activeSheet->setCellValueByColumnAndRow($key + 1, 1, $value);
        }

        $col = 0;

        foreach ($rowList['columnData'] as $row => $item)
        {
            foreach ($item as $col => $value)
            {
                Yii::info($value['val']);
                $activeSheet->getCellByColumnAndRow($col + 1, $row + 2)->setValueExplicit($value['val'], DataType::TYPE_STRING);
                //$activeSheet->setCellValueByColumnAndRow($col + 1, $row + 2, "".$value['val']);
            }
        }

        $spreadsheet->getActiveSheet()->setTitle('数据');

        // Set active sheet index to the first sheet, so Excel opens this as the first sheet
        $spreadsheet->setActiveSheetIndex(0);

        $filename = $rowList['title'];
        // Redirect output to a client’s web browser (Xls)
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename=' . $filename);
        header('Cache-Control: max-age=0');
        // 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

        $writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
        $writer->save('php://output');
        exit;
    }
}

3、使用（参数可以参考封装类的提示）

$rowList = [
    'title' =>   '反馈' . date('His') . '.xlsx',
    'columnName' => $columnNames,
    'columnData' => $columnData
];

ExportHelper::exportData($rowList);  //记得引入命名空间

 

这样子，直接调用封装的类后，之后php将数据下载成excel就简单啦
