problem with header

Hi

I am using Db ( mysql) to blob in some files. The loading into db is okay, but the problem is when viewing the stored data of different format. Some I could easily open it, and others gives error. I could view/open images and html but opening a .doc or .xls is a problem. It pop up message : " internet explorer cant download grade.php from localhost "
OR else sometimes it opens in plain html format with funny characters ( ascii code) .

My enviroment is :
Win Apache
Php 4.1
Mysql
Window 98
Office 97


Below is my code:
<?
include("../lib/config.inc");
include("../lib/dblib.inc");
include("../lib/lib.inc");
$query="select * from ece1011_1_1 where stdnt_rollnum=890234 ";
$result=mysql_query($query) or die("Unable to get file :".mysql_error());
$data=mysql_result($result,0,"file_data");
$type=mysql_result($result,0,"file_type");
$file =mysql_result($result,0,"file_name");
Header("Content-type: $type");
//print($data);
//echo " $type, $file<br>";
echo $data;
?>


Thanks for you guys comments and help. I need to solve this asap.

Thanks

Hey Rathur,
What header types have you saved for them in the database? That might be where the problem lies. Also, are the included files outputting anything? THey shouldnt be.

Hi mytch

The include files doesnt print anything. They contain variables defined and some functions which need to be invoked.

The type of file is fetched as in your article. ( fecthed by PHP into the form_data, form_data_type ) Is that what you meant by header type ?
for word the type loaded is application/msword .
The imagers ,text and html files can be opened easily by the script but so strange the word, xls cant.
PLease do advice .. need to solve this asap

Thanks
