PHP导出EXCEL文件时总是自动打开，请问如何防止？
<code class="lang-php"> header("Content-Type: application/vnd.ms-excel; charset=utf-8");
header("Content-Disposition: attachment; filename=$outputFileName");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private", false);
$xlsWriter->save("php://output");
</code>

改成
<code>header('Content-Type: application/octet-stream');
</code>
