Perhaps it could be mentioned that if you use prepends or includes, 
it might be wise to put in a check to see if the headers have 
already been sent. Otherwise with error notification turned down low,   
you might miss the fact that the headers you are trying to send 
are not going out. Something like:

if (headers_sent($filename, $linenum)) {
   trigger_error( "Problem: Headers already sent in $filename on line
$linenum ");
   exit;
} 

header( 'whatever...

And further it could be pointed out that it is a 
*bad* practice (worse than usual) to use PHP versions 
before 4.3.4, if you plan to use headers_sent.

see:
 http://bugs.php.net/bug.php?id=25701 

(if you move up to PHP 5 and you could use headers_list 
http://us2.php.net/headers_list to see what's going on --  
or will go on -- with headers)
