Session Problem with Header

[smartic]

i'm having problem with session_start() to force the browser to download file with this function:

[PHP]
session_start();
function force_download($file){
if ((isset($file))&&(file_exists($file))) {
header("Content-type: application/force-download");
header('Content-Disposition: inline; filename="' . $file . '"');
header("Content-Transfer-Encoding: Binary");
header("Content-length: ".filesize($file));
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . $file . '"');
readfile("$file");
} else {
echo "No file selected";
}
}
force_download("EGYMIDICA 2008.pdf");
[/PHP]
when i delete the session_start() function the browser download the file with no problem how can i solve this with session?

Hi.

What is the problem?
Are you getting any errors?

As far as I can see, there is nothing wrong with that.
The only thing I can think of is that the session_start() function is generating a warning, in which case adding a @ sign in front of it may fix the problem.
