So why not do > that? Perhaps a switch block would serve your needs better? I took your advice and put this up--any thoughts or advice would be appreciated. Is the switch setup below the sort of thing you were talking about? I altered it slightly overall to set a specific header file, instead of a graphic, which is more useful. <? // header generation script // define path to includes & header folder where // include files live $includepath = '/home/user/public_html/inc'; (( would be in a global include file, just here for clarity )) // see what host is invoked switch ($_SERVER['HTTP_HOST']) // check hostname { case 'domain.com': // define host $Header = '/inc/main.header.inc'; // define header file break; // next case 'www.domain.com': $Header = '/inc/main.header.inc'; break; case 'host1.domain.com': $Header = '/inc/host1.header.inc'; break; case 'host2.domain.com': $Header = '/inc/host2.header.inc'; break; case 'host3.domain.com': $Header = '/inc/host3.header.inc'; break; case 'host4.domain.com': $Header = '/inc/host4.header.inc'; break; case 'host5.domain.com': $Header = '/inc/host5.header.inc'; break; // etc., etc. default: $Header = '/inc/illegalhost.header.inc'; // define header } // call the include header file for that host if (file_exists("$includepath/$Header")) { // include valid? include stripslashes("$includepath/$Header"); // yup, include } else { echo "FAILURE MESSAGE OF SOME SORT"; // nope exit; } ?> (rest of page) I figure I can get a regexp in there somehow so I don't need two entries for the main domain.com and it's www c name, either... need to add that. I'm also sort of paranoid about unchecked includes in PHP and getting compromised--is doing a check like I am here for the include file's existence worthwhile or even useful to protect against possible problems? thanks, Joe
