Hello, I have an excel file that I am generating. If I copy over the generated file and then open it in excel, it works fine, if I try to let the user download it using the headers below, when I then open it excel complains that it is an unrecognizable format and the info is garbled...any ideas??? Thanks! header('Pragma: public'); header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past header('Last-Modified: '.gmdate('D, d M Y H:i:s') . ' GMT'); header('Cache-Control: no-store, no-cache, must-revalidate'); // HTTP/1.1 header('Cache-Control: pre-check=0, post-check=0, max-age=0'); // HTTP/1.1 header ("Pragma: no-cache"); header("Expires: 0"); header('Content-Transfer-Encoding: none'); header('Content-Type: application/vnd.ms-excel;'); // This should work for IE & Opera header("Content-type: application/x-msexcel"); // This should work for the rest header('Content-Disposition: attachment; filename="myfile.xls"'); readfile("/tmp/myfile.xls");
