PHP 5.1 suggestion:

include ( string filename )
include_once ( string filename )
require ( string filename )
require_once( string filename )

If you include/require file codding with UTF-8, you include/require to inside output data chr(239).chr(187).chr(191) (3-byte UFT-8 header from incluging/requiring file).
It is no good. It will be good to add two paramerters:

include ( string filename, int start [, int length] )
include_once ( string filename, int start [, int length] )
require ( string filename, int start [, int length] )
require_once( string filename, int start [, int length] )

expamle for UTF-8:

include ( 'file-utf-8.php', 3 )
include_once ( 'file-utf-8.php', 3 )
require ( 'file-utf-8.php', 3 )
require_once( 'file-utf-8.php', 3 )
