将文件名更改为所需的路径，

$name = '/path/to/folder/xyz.xlsx';
$objWriter->save($name);

对我有效...

$objWriter->save($filename);

....将$filename的值更改为您要保存文件的位置的文件路径，例如

$filename = '/path/to/folder/test.xlsx';
$objWriter->save($filename);

如果您在php文件中包含以下标题，您的用户将弹出一个下载选项：

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=$filename");
header("Content-Transfer-Encoding: binary ");

使用PHPExcel下载Excel：

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');

对于使用Excel5 Writer创建的.xls文件：

header('Content-Type: application/vnd.ms-excel'); //mime type

或
对于使用Excel2007 Writer创建的.xlsx文件：

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); //mime type

header('Content-Disposition: attachment;filename="you-file-name.xlsx"'); //tell browser what's the file name
header('Cache-Control: max-age=0'); //no cache 
ob_end_clean();
$objWriter->save('php://output'`enter code here`);
exit();
