cookie and header

[Anon]

Hi,

I set a cookie like this :

setcookie("memberid", $memberid, time() + 3600 24 730);

But I get the following error message : "Cannot add header information - headers already sent by..."

My cookie is not set !

What can I do ?

P.S. : I'm using the following code at the beginning of my page, I think the problem could be because of it :

<?
// session created ? if not, create one
if ($PHPSESSID)
session_start($PHPSESSID);
else
session_start();
?>

Thanks for helping.

header() must be called before any text is sent, but session functions do not send text, so that is not the problem. It is likely that you have HTML whitespace before cookie().
