I'm having problems when I tried using a navigation script. The script works fine, except for one thing. When I put index.php?page=news, im given the news page. The problem is that when I try setting a cookie im given :
Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/index.php:8) in /var/www/html/myplace/login.php on line 93
Is there a way i could fix this without using iframes?

In PHP, you must set cookies, change the header type, etc. before anything is sent to the browser. There are two ways to get around this.
One, move the setcookie function in your script so it above everything (<html>, doctype, etc.) so that it will be set before the page is loaded and the header error won't appear.
Two, if you must have the cookie where it is, you can use a little work around.
Above everything (<html>, doctype, everything), put:
Then right at the end of your page put:

<?php ob_start() ?>
Then right at the end of your page put:
<?php ob_end_flush() ?>
