Question

PHPExcel＆＃39; simple exmple正在我本地的机器设置上正常工作。它正在下载.xlsx文件，MS-Excel程序很高兴打开它。

现在我将此代码复制到我的WordPress插件，以允许从 WordPress管理员部分下载Excel

if ( file_exists(CHECKIN_PLUGIN_DIR . '/lib/PHPExcel.php') ) {
    ob_end_clean();
    ob_start();

/** Include PHPExcel */
require (CHECKIN_PLUGIN_DIR . "/lib/PHPExcel.php");
require (CHECKIN_PLUGIN_DIR . "/lib/PHPExcel/Writer/Excel2007.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('B2', 'world!')
            ->setCellValue('C1', 'Hello')
            ->setCellValue('D2', 'world!');

// Miscellaneous glyphs, UTF-8
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A4', 'Miscellaneous glyphs')
            ->setCellValue('A5', 'éàèùâêîôûëïüÿäöüç');

// 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);

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

// Save Excel 2007 file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
//$objWriter->save("/home/user/ExcelTests/test01.xlsx");
$objWriter->save('php://output');  

exit;
}
?>
<div class="wrap">
....

但是excel无法打开下载的文件，它显示Different format than specified by the file extension....并且打开时会显示一堆六角字符

PKU~AG�D�X�[Content_Types].xml��MN�0��"�%nY ��vAa �(0��ؖg�w{&i�@�nbE�{��y��d۸l m�����X�(���)���F��;@1_�����c)j�x/%��E��y� �QĿi!��K�

当我更改代码以将其保存为硬盘中的文件时，可以毫无问题地打开它。

if ( file_exists(CHECKIN_PLUGIN_DIR . '/lib/PHPExcel.php') ) {
    ob_end_clean();
    ob_start();

/** Include PHPExcel */
require (CHECKIN_PLUGIN_DIR . "/lib/PHPExcel.php");
require (CHECKIN_PLUGIN_DIR . "/lib/PHPExcel/Writer/Excel2007.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('B2', 'world!')
            ->setCellValue('C1', 'Hello')
            ->setCellValue('D2', 'world!');

// Miscellaneous glyphs, UTF-8
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A4', 'Miscellaneous glyphs')
            ->setCellValue('A5', 'éàèùâêîôûëïüÿäöüç');

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

// Save Excel 2007 file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save("/home/user/ExcelTests/test01.xlsx");
//$objWriter->save('php://output');

exit;
}
?>
<div class="wrap">

同样适用于Excel5格式。

但是通过浏览器下载的CSV没有问题。

任何帮助？

更新

vi浏览器下载的文件为here

保存到filesyestem的文件为here

在Hexa编辑器中查看时，在下载文件中的PK之前找到了额外的换行符0A

我尝试使用trim

删除该换行符

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

// Save Excel 2007 file
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');

$ob_content = ob_get_contents();
ob_end_clean();
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="export.xlsx"');
header('Cache-Control: max-age=0');
echo trim($ob_content);
exit;

但即使在0A文件开头就有了。{/ p>

Answer 1

我在我的项目中使用此代码，这很有效：

$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);   

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

$objWriter->save('php://output');

Answer 2

这几乎可以肯定意味着您正在输出xls文件内容之外的其他内容，例如空格或BOM表头。在文本编辑器中打开文件，并在最开始（PK字符之前）或文件结尾处查找任何空格字符，如制表符，空格，换行符等，或者查找文件中任何明显的PHP错误消息本身。

通过浏览器下载的PHP Excel文件未由MS-Excel / OpenOffice打开
