PHPExcel强制下载问题

我知道这个问题可能被分为几个部分提出，但我找不到这个问题的确切答案。我使用PHPExcel生成一个Excel文件（很明显），代码可以生成文件，但当我包含用于强制下载的代码时，它会破坏文件。我最新版本的脚本如下所示：

function make_xls_spreadsheet(){

/** Error reporting */
error_reporting(E_ALL);

/* Set the save path */
define('XLSX_SAVE_PATH', 'tmp/');

/** Include path **/
set_include_path(get_include_path() . PATH_SEPARATOR . 'Classes/');

/** PHPExcel */
include 'PHPExcel.php';

/** PHPExcel_Writer_Excel2007 */
include 'PHPExcel/Writer/Excel2007.php';


/* Create a new PHPExcel Object */
$objPHPExcel = new PHPExcel();


/* Add some metadata to the file */
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw");
$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");
$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.");

/* Set active worksheet to first */
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('Segments');

/* Add some data to the worksheet */
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('B2', 'world!');
$objPHPExcel->getActiveSheet()->SetCellValue('C1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('D2', 'world!');


/* Write to server */
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);

$filename = "tony1.xlsx";

// Works fine up to here

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');

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


echo "DONE!";

$objPHPExcel->disconnectWorksheets();
unset($objPHPExcel);



}

请记住，当我删除强制代码部分时，文件会生成，并且我可以通过FTP将其下载。但是，生成和强制生成文件都会导致文件损坏。通常我可以单击“打开并修复”（Office2011 MacOSX），但显然这是不可取的

谁能帮我理解一下：

为什么会产生腐败？以及为什么我不强制下载时它工作正常

保存/强制的正确顺序是什么（使用PHP的header（）函数）

如果有更好的方法

非常感谢

****更新****这是我点击“修复”时的代码：

修复结果为tony1 03178.xml
在文件“Macintosh HD:Users:tony.diloreto:Downloads:tony1.xlsx”中检测到错误
Excel已完成文件级验证和修复。此工作簿的某些部分可能已被修复或丢弃。

这会将excel文件输出到浏览器：

readfile(XLSX_SAVE_PATH . $filename);  

然后你把它吐出来，它会成为浏览器下载的excel文件的一部分

echo "DONE!";

基本上你是在发送

[excel data]DONE!

当Excel仅期望

[excel data]

//答案实际上属于@Dagon

答案其实很简单，只需要一个简单的

exit（）呼叫

最终代码块：

function make_xls_spreadsheet(){

/** Include path **/
set_include_path(get_include_path() . PATH_SEPARATOR . 'Classes/');

/** PHPExcel */
include 'PHPExcel.php';

/** PHPExcel_Writer_Excel2007 */
include 'PHPExcel/Writer/Excel2007.php';


/* Create a new PHPExcel Object */
$objPHPExcel = new PHPExcel();

/** Determine filename **/
$filename = "tony1.xlsx";

/** Set header information **/
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="' . $filename . '"');
header('Cache-Control: max-age=0');


/* Add some metadata to the file */
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw");
$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");
$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.");

/* Set active worksheet to first */
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('Segments');

/* Add some data to the worksheet */
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('B2', 'world!');
$objPHPExcel->getActiveSheet()->SetCellValue('C1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('D2', 'world!');


header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');

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

exit();

}

尝试按如下方式修改File.php：

受保护的静态$\u useUploadTempDirectory=TRUE

在文件夹phpexcel/Classes/phpexcel/Shared中（这不是最好的方法，但对我来说很有效）。
关闭但没有雪茄。它仍然说一些内容“不可读”，必须修复。还有其他想法吗？与其将其保存到文件中，不如将其保存到
php://output
，除非您需要本地副本，否则
$objWriter->save（'php://output');谢谢-那么我需要readfile（）行吗？如果我这样做，它会变成什么？替换行
$objWriter=
之后的所有内容。。使用
$objWriter->save（'php://output');无骰子-脚本的新底部是：
头（'Content-Type:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'）；标题（'Content-Disposition:attachment；filename=“.”.$filename.'”）；标头（'Cache-Control:max age=0'）$objWriter=PHPExcel_IOFactory:：createWriter（$objPHPExcel，'Excel2007'）$objWriter->save命令php://output');      返回
fyi“没有骰子”和“接近但没有雪茄”。这是我今天回答的第二个问题，答案是
exit（）
function make_xls_spreadsheet(){

/** Include path **/
set_include_path(get_include_path() . PATH_SEPARATOR . 'Classes/');

/** PHPExcel */
include 'PHPExcel.php';

/** PHPExcel_Writer_Excel2007 */
include 'PHPExcel/Writer/Excel2007.php';


/* Create a new PHPExcel Object */
$objPHPExcel = new PHPExcel();

/** Determine filename **/
$filename = "tony1.xlsx";

/** Set header information **/
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="' . $filename . '"');
header('Cache-Control: max-age=0');


/* Add some metadata to the file */
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw");
$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");
$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document");
$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.");

/* Set active worksheet to first */
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setTitle('Segments');

/* Add some data to the worksheet */
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('B2', 'world!');
$objPHPExcel->getActiveSheet()->SetCellValue('C1', 'Hello');
$objPHPExcel->getActiveSheet()->SetCellValue('D2', 'world!');


header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');

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

exit();
