Question

我们已经在我们的生产环境中使用PHPExcel已经超过4年了，直到上周Excel 2010和Excel一直使用PHPExcel时没有任何问题。 2103无法打开PHPExcel生成的许多xls文件之一。我们得到的错误是

错误：＆＃34; Excel在文件中找到了不可读的内容。你想恢复这个工作簿的内容吗？如果您信任此工作簿的来源，请单击“是”。＆＃34;

我们尝试修复并逐步完成我们发现的其他建议，但都没有效果。

生成许多文件后，我们至少能够始终如一地重现此问题。虽然看起来很奇怪但Excel 2010＆amp; 2013年在Windows 7和Windows上运行10无法打开由phpExcel生成的文件大小介于6914K - 6977K之间的任何文件。

我们无法找到Excel 2010/2013无法打开这些文件的任何解决方案或原因。我们错过了什么吗？提前感谢任何建议。

我们正在使用......

PHPExcel：1.8 Webserver：Apache / 2.2.15（Unix）＆amp;在Red Hat上运行的PHP 5.3.3

$objPHPExcel = new PHPExcel();

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save("reports/$filename"); 

$objPHPExcel->disconnectWorksheets();
unset($objPHPExcel);
unset($objWriter);
echo "<a href=reports/$filename>Download this file</a><br><br>";

Answer 1

尝试改变这一点：

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

对此：

$objWriter = new PHPExcel_Writer_Excel2007 ( $objPHPExcel );

将扩展程序 .xls 更改为 .xlsx

Excel 2010无法打开由PHPExcel创建的特定大小的xls文件
