quick cookie error question

[pinehead18]

Warning: Cannot modify header information - headers already sent by (output started at /home/p/www/cookie.php:2) in /home/p/www/cookie.php on line 4

How is that possible when the only code i have on this page is..

[php[
<?php

    setcookie("user","pinehead",time()+5897755); 

?>

<?PHP

echo $_COOKIE['user'];
?>

[/code]

What does this mean and how do i fix it?

Thank you

dont double post, and like i said

<?php 

    setcookie("user","pinehead",time()+5897755); 

?>       

<?PHP    

        echo $_COOKIE['user']; 
?>

works fine, why do you have 2 <?php ?> tags?
