php excel 下载文件

Question

开发人员
我正在使用 Yii1，我想使用 PHPExcel 扩展生成报告，但我的文件尚未准备好下载，而是显示在控制台中。我还设置了标题，但文件还没有准备好下载。我找不到确切的答案。请解决我的问题

public function GenerateReport($dataProvider)
{

    $phpExcelPath = Yii::getPathOfAlias('ext.phpexcel.Classes');
    include($phpExcelPath . DIRECTORY_SEPARATOR . 'PHPExcel.php');

    $objPHPExcel = new PHPExcel();
    $fileName = 'report-'.uniqid().'.xlsx';
    $objPHPExcel->getProperties()->setCreator("Palash Gupta");
    $objPHPExcel->getProperties()->setTitle($fileName);
    $objPHPExcel->getProperties()->setSubject("Placement Student List");
    $objPHPExcel->getProperties()->setDescription("Placement Student List");
    $objPHPExcel->setActiveSheetIndex(0);

    $rowCount = 1;
    $objPHPExcel->getActiveSheet()->SetCellValue('A' . $rowCount, 'Name');
    $objPHPExcel->getActiveSheet()->SetCellValue('B' . $rowCount, 'Course');

    $rowCount = 2;
    foreach ($dataProvider->getData() as $data)
    {
        $objPHPExcel->getActiveSheet()->SetCellValue('A' . $rowCount, $data['sd_fname']);
        $objPHPExcel->getActiveSheet()->SetCellValue('B' . $rowCount, $data['fk_mc_id']);
        $rowCount++;
    }

    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
    header('Content-Disposition: attachment;filename="'.$fileName.'"');

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    $objWriter->save('php://output');

}

Answer 1

试试这个：

// Redirect output to a client’s web browser (Excel2007)
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
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
