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
