使用 PHPExcel 下载 xls 文件时出现损坏

在我当前的项目中，我使用 PHPExcel 1.7.8 将数据导出到 Excel。按照建议，我在项目中成功配置了它，并成功生成了 xls 文件并存储了它，但是当我尝试下载 xls 文件时，我损坏了 xls 文件，而没有收到任何错误消息。我有相同的以下代码。

/** Error reporting */
if (PHP_SAPI == 'cli')
     die('This example should only be run from a Web Browser');

/** Include PHPExcel */
require_once '../Classes/PHPExcel.php';

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Set document properties
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw")
      ->setLastModifiedBy("Maarten Balliauw")
      ->setTitle("PHPExcel Test Document")
      ->setSubject("PHPExcel Test Document")
      ->setDescription("Test document for PHPExcel, generated using PHP classes.")
      ->setKeywords("office PHPExcel php")
      ->setCategory("Test result file");

// Add some data
$objPHPExcel->setActiveSheetIndex(0)
         ->setCellValue('A1', 'Hello')
         ->setCellValue('B1', 'world!')
         ->setCellValue('C1', 'Hello')
         ->setCellValue('D1', 'world!');

// Miscellaneous glyphs, UTF-8
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A2', 'Miscellaneous glyphs')
            ->setCellValue('B2', 'This is test text by me');

// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Simple');


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

// Redirect output to a client’s web browser (Excel5)
header("Content-Type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=\"filename.xls\"");
header("Cache-Control: max-age=0");

// Save Excel 2007 file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save(str_replace('.php', '.xls', __FILE__));
$objWriter->save("php://output");
exit;

谢谢。

你能试试这个吗？就在你之前

header("Content-Type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=\"filename.xls\"");
header("Cache-Control: max-age=0");

put ob_end_clean();.

您的输出缓冲区可能有问题。
