A warning about Cookies

[HSN]

Hello,

I'm developing a script in PHP and when I use a setcookie function I see the following warning:

Warning: Cannot add header information - headers already sent by (output started at C:\apache\htdocs\chapter_6_training\test.php:3) in C:\apache\htdocs\chapter_6_training\test.php on line 8


I used:

setcookie ('mycookie',$myname);

of even if I use a header(), it gives me the same warning!

like header ("Location: ........");

----
Please help me!

turn on output buffering.
i.e. put
ob_start();
at the beginning of your script

Nothing changed!

Still:

Warning: Cannot modify header information - headers already sent by (output started at.....

Make sure you don't have an empty line or a space before <?php right at the top of the script, if that doesn't work post the first 10 lines of the script (if it's long) else all of it.

if ($un && $ps )
{
require_once ('mysql_connect.php');

$query = " SELECT user_id FROM users WHERE (username = '$un' AND password = PASSWORD ('$ps') ) ";
$result = @mysql_query ($query);

$num = mysql_num_rows($result);

if ( $num )
{
setcookie ('first_name', $row[1] );
setcookie ('user_id', $row[0]);
echo "ok!";
exit ();
}
else
{
$message = '<p>Your username and password do not match our records.</p>';
}
mysql_close();
}



This is just a part of my incomplete script. In this if statement I used a setcookie.
I also removed the empty lines before <?php but...
this time it's not giving my warnings anymore, it does not display the login.php page!!
