I seem to get the following error on this page...
Warning: Cannot modify header information - headers already sent by (output started at /home/trancien/public_html/index.php:12) in /home/trancien/public_html/index.php on line 110

Here's my code. What am I doing wrong?
The lines it refers to are where the login success post script is, specifically the 4 lines with "setcookie"

it also will speed up your PHP scripts as the internal writes go to a buffer instead of being outputed to the browser every X bytes. In fact... Output buffering was the difference between a PHP script on my computer running in 0.3 seconds compaired to 0.05 seconds or something rediculous like that anyway
