Help?

Well, im making a very small PHP script, here it is-

PHP Code:

 <?php
 // ####################### SET PHP ENVIRONMENT ###########################
 error_reporting(E_ALL & ~E_NOTICE);
 
 // #################### DEFINE IMPORTANT CONSTANTS #######################
 define('NO_REGISTER_GLOBALS', 1);
 define('THIS_SCRIPT', 'biography');
 
 // ################### PRE-CACHE TEMPLATES AND DATA ######################
 // get special phrase groups
 $phrasegroups = array();
 
 // get special data templates from the datastore
 $specialtemplates = array();
 
 // pre-cache templates used by all actions
 $globaltemplates = array(
 'biography'
 );
 
 // pre-cache templates used by specific actions
 $actiontemplates = array();
 
 // ######################### REQUIRE BACK-END ############################
 require_once('./global.php');
 
 // ### ALL DONE! SPIT OUT THE HTML AND LET'S GET OUTA HERE... ###
 
 eval('$navbar = "' . fetch_template('navbar') . '";');
 eval('print_output("' . fetch_template('biography') . '");');
 
 
 ?>

Although, whenever a guest visits it, this error shows up-

Unable to add cookies, header already sent.
File: /home/****/public_html/biography.php
Line: 1

How would I get it so that guests would be able to view it?

Check for any whitespace before the <?php and remove it.
