PHPExcel_Writer_Exception，显示消息“无法关闭zip文件php://output". [英] PHPExcel_Writer_Exception with message "Could not close zip file php://output."
问题描述
我正在使用PHPExcel将一些数据导出到excel文件中.我希望脚本在创建后立即将excel文件发送给用户.这是我的测试代码:
try{
/* Some test data */
$data = array(
array(1, 10 , 2 ,),
array(3, 'qqq', 'some string' ,),
);
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
/* Fill the excel sheet with the data */
$rowI = 0;
foreach($data as $row){
$colI = 0;
foreach($row as $v){
$colChar = PHPExcel_Cell::stringFromColumnIndex($colI++);
$cellId = $colChar.($rowI+1);
$objPHPExcel->getActiveSheet()->SetCellValue($cellId, $v);
}
$rowI++;
}
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="export.xlsx"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
}catch(Exception $e){
echo $e->__toString();
}
在我的本地服务器上(Windows 7 x64, Php 5.3.8, Apache 2.2.21)，我得到一个有效的xlsx文件.没有错误.
但是实时服务器(Linux 2.6.32-5-amd64, PHP 5.3.3-7+squeeze13, Apache 2.2.16)上有问题.该脚本允许浏览器下载包含以下内容的"export.xlsx"文件:
exception 'PHPExcel_Writer_Exception' with message 'Could not close zip file php://output.' in /var/www/someuser/data/www/somedomain.com/libs/PHPExcel/Writer/Excel2007.php:348

PHP不在安全模式下运行. "open_basedir"选项为空(已注释掉).
我在PHPExcel文件中找到了这样的代码:
if ($objZip->close() === false) {
throw new PHPExcel_Writer_Exception("Could not close zip file $pFilename.");
}
所以出现问题的原因是$objZip->close() === false，其中$objZip是ZipArchive类的实例.
问题的原因是什么，我该如何解决?谢谢.
保存到php://output时，导致此错误的最常见原因是open_basedir限制，其中不包含有效的系统临时文件夹(例如
一种可能的解决方法是将文件写入您确实拥有完全写入权限的目录中的文件系统中，然后使用readfile()在删除文件之前将该文件流式传输到php://output >
I'm using PHPExcel to export some data to user in an excel file. I would like the script to send the excel file to the user immediately after it's creation. Here is my test code:
try{
/* Some test data */
$data = array(
array(1, 10 , 2 ,),
array(3, 'qqq', 'some string' ,),
);
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
/* Fill the excel sheet with the data */
$rowI = 0;
foreach($data as $row){
$colI = 0;
foreach($row as $v){
$colChar = PHPExcel_Cell::stringFromColumnIndex($colI++);
$cellId = $colChar.($rowI+1);
$objPHPExcel->getActiveSheet()->SetCellValue($cellId, $v);
}
$rowI++;
}
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="export.xlsx"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
}catch(Exception $e){
echo $e->__toString();
}
On my local server (Windows 7 x64, Php 5.3.8, Apache 2.2.21) I get a valid xlsx file. There are no errors.
But there is problem on the live server (Linux 2.6.32-5-amd64, PHP 5.3.3-7+squeeze13, Apache 2.2.16). The script lets the browser to download the "export.xlsx" file with such content:

PHP is NOT running in Safe Mode. The "open_basedir" option is empty (it's commented out).
I have found such code in the PHPExcel files:
if ($objZip->close() === false) {
throw new PHPExcel_Writer_Exception("Could not close zip file $pFilename.");
}
So the reason of the problem is that $objZip->close() === false where $objZip is an instance of ZipArchive class.
What is the reason of the problem and how can I solve it? Thank you.
The most common cause of this error when saving to php://output is an open_basedir restriction that doesn't include a valid system's temp folder (e.g. /tmp), or permissions for the system's temp folder... suhosin can also affect this, even when the obvious permissions appear to be set correctly.
A possible workround is to write the file to the filesystem in a directory that you know you do have full privileges to write, and then use readfile() to stream that file to php://output before deleting the file
