当我使用PHPExcel生成Excel报告时，我会收到以下错误：
"'test.xls'的文件格式和扩展名不匹配。该文件可能已损坏或不安全。除非你信任它的来源，否则不要打开它。你想打开它吗？"
这是我的设置——PHP 5.4/PHPExcel 1.7.9/Windows 7
当我单击"确定"打开不安全的excel文件时，它要么是空的，要么是胡言乱语。
HTML代码：它允许用户从下拉列表中选择报告，然后如果他们想要预览报告、生成excel文件或创建PDF文件，则可以选择按钮。但在这种情况下，我正在努力让excel文件生成。

这是PHP文件：PHPExcel代码在其中执行。我构建了if-else语句来指示用户选择了哪个报告并仅运行该报告。

一周前，报告可以使用上面的代码生成，但最近由于某种原因，它给了我一个错误，即文件可能已损坏或不安全。我的PHPExcel类文件在我的项目文件夹中，因此可以引用路径。我不确定如何修复这个错误。
如果有人能在这个问题上有所作为，我将不胜感激
谢谢。
请使用
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
而不是
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
我试过了，效果很好。感谢您的
