Hello, the generated xls file opens in MS Excel 2013 with the warning "The file format does not match the file permission...", as if you click "Yes" and everything opens fine, but I would like it without any warnings.
Code snippet:

header("Content-Type: application/vnd.ms-excel; charset=windows-1251");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Content-Disposition: attachment; filename=filename.xls);

echo<<<HTML
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=windows-1251" />
</head>
<body>
<table border="1" cellspacing="0" cellpadding="0">
/* вагон строк */
</table>
</body>
</html>
HTML
die();

If you want without warnings - generate a real valid xls-file.
In your case, all of a sudden , the file permission doesn't really match the content.
