Question

I am using PhpExcel to download reports as excel in my codeigniter application. When I try to download my report its showing some characters on the browser instead of downloading the file. This has worked fine in localhost but not working in the server. I dont know whats the problem. Here is my code:

Answer 1

Try this
ob_clean();
ob_start(); # added
header('Content-type: application/vnd.ms-excel; charset=UTF-8" ); # Improved with UTF charset
header('Content-Disposition: attachment;filename="' . $filename . '.xls"');
header('Cache-Control: max-age=0');
ob_clean(); # remove this
