[SOLVED] Why does this code give "header already sent" error??

[JJohnsenDK]

Hey

 

Here is the code

 

<?php
include('mysql_connect.php');
$query = mysql_query("SELECT counter FROM `counter` WHERE `counterId` = '1' LIMIT 1");
$sitewide=mysql_fetch_array($query);
if(!isset($_COOKIE[counter])){
	$sitewide['counter']++;
	mysql_query("UPDATE `counter` SET `counter` = '$sitewide[counter]' WHERE `counterId` = '1' LIMIT 1");
	setcookie('counter', 'snuffalufagus', 2+time()); 
}
?>

 

it starts at line 1 and ends at line 10 in a script.

 

It comes up with this error:

Warning: Cannot modify header information - headers already sent by (output started at C:\Programmer\xampp\xampp\htdocs\katrinelund\mysql_connect.php:15) in C:\Programmer\xampp\xampp\htdocs\katrinelund\index.php on line 8

 

I tried leaving out the tabs spaces, but that didnt help.

 

Any help is would be nice

Canu show ur index.php code.

OR:

 

put this ayt very top of ur index.php page.

<?php

ob_start();

?>

[bsprogs]

If I remember correctly, header information must be sent before ANY html is written to the page.

 

Check this file:

C:\Programmer\xampp\xampp\htdocs\katrinelund\mysql_connect.php

 

and see what line 15 says.

Thanks guys that worked

 

Can you also tell me how the setcookie() function works?

 

I making a counter, as you properly can see and i want it to kill the cookie after 10 mins, so the homepage gets a new hit from the user after 10 min.

 

How do i do that?
