Headers

[we_win]

I am getting this warning
Cannot add header information - headers already sent

I am very well aware of the cause.
I have also figured out that "<br>" gets added in from some file that is probably auto prepended before i sent the headers. So thats causing the problem

I am lookin for a quick n dirty fix. is there any way where i could clear the contents (i.e output) before i send any headers ????

I really donot want to waste my time in looking for the file that gets appended automatically, that would have to make me to go through all the HTML templates and look out for one that gets appended.

what i want to do is to clear the output before i send any headers

Heres the code sample
<? header("Content-type: application/vnd.ms-excel");

$max_rows = 36;
$wo_number = $asn_info[0]["wo_no"];
$parameter = $PHP_SELF."?wo_number=".$wo_number;
?>

It seems like "<br>" gets inserted from some auto appended file
before i send the headers.....

i wud really appreciate ur help !!!!
thanks

and the header() line is the first line in your script? if not, this is what can happen:
<?
if(something) { }
else {
?>
<? header(...);
}
?>

The space between your first ?> and your second <? is the line break which would go into output stream before your header call.
I have seen a lot of these types of problems.
Directly on your question, I don't think there is a way to discard the buffer without sending. And even if it was, it would be unreliable, since you would have no way to ensure that previous stuff is still in the buffer, rather than already transmitted to the browser.
