Some problem with switch and setcookie

[Walle]

Cannot get this code working. I’m try to set cookie but only get Warning: Cannot modify header information - headers already sent by .... on line 8

<?php
if(isset($_GET['set']))
{
$l = $_GET['set'];
switch($l)
{
case $l:
setcookie("lang", "$l", time()+600, '/');
break;
}
}
?>
<a href="?set=1">1</a> | <a href="?set=2">2</a>

You've got something on line 8 of the file that's generating output. You can't set any headers after generating output.

I know that about output but it just want work for some reason. There must be something else in this case. I run similar code in a other page and include another with that link only then it work. But not with single page.

Can you see some output on this code?

Is the code you posted at the top of the script in question? If not, show lines 1-8 of the file referenced in the error message.

Actually, there should be two files and line numbers referenced; one pointing out where the header was (supposed to be) set, and the other stating where the output started. Reading the original post I can't tell which line number was left out.

I got this work now. but I relay don’t know what problem was or what I did. The biggest known change I did was change "time()+600" to "time()[phone]".
Works now without header output problem and cookies saving as it should.
