dump data, and save as a file

Hi everyone, I want to dump some data from mysql into a file, and use php to force the browser to pop a download file window. This seems a simple procedure, but I am having trouble to make it work with IE. The following is what I did: ******************************** ob_start(); $query = "SELECT * FROM table"; $result=mysql_query($query); while($row=mysql_fetch_array($result)) { echo $row['data']; } header("Cache-control: private"); header("Content-Type: application/txt"); header("Content-Disposition: attachment; filename=test.txt); //Note: I also tried: header("Content-Disposition: inline; filename=test.txt); ob_end_flush(); ********************************* It seems OK with Netscape, but with IE, all I got is all data displayed on the screen even with ob_start(). I also tried "echo" the data after "header()", I have the same result. I have spent a long time on this, and searched for information on www.php.net, but can not find an answer. Your help is highly appreciated. Thanks in advance. Ruth
