Cannot modify header information - Headers already sent

Can anyone tell me what is wrong with this code?

<?php
if (isset($_COOKIE['referralcookie']['refid'])) {
$url = $row_rsCookieReferral['cookiereferral_hoplink'];

header("Location: $url");
}
?>




['referralcookie']['refid'] is a cookie I have set and
rsCookieReferral is a recordset I have on my page

My main issue is that I am getting this error:

Warning: Cannot modify header information - headers already sent by (output started at /home/XXXMY_USERNAMEXXX/public_html/index.php:69) in /home/ezcogtem/public_html/index.php on line 73

Moved to PHP forum .

Look around here:
http://www.php.net/manual/en/function.session-start.php

Their is a command to have it so you can add spaces after session start, but I forgot...

Hi half21back and welcome to TSDN

The error :

is telling you your script has written output to the browser before you have issued your redirect - this is not allowed, thus the error. You can either find the write to the browser, this could be a php function ie echo, print() or could be as simple as whitespace in the html code around your php script. Take a look at line 73. If you cannot find the problem post the whole of index.php into this thread.

Thank you guys,

Here is the updated code:

[PHP]
<?php
if (isset($_COOKIE['referralcookie']['refid'])) {
$url=$row_rsCookieReferral['cookiereferral_hoplink'];
header("Location: $url");
}
?>
[/PHP]

My page now works correctly. I believe it had to do with the white space as mentioned.
