$_SERVER is, thankfully, _mostly_ populated by the web server, not the
client. HTTP_HOST certainly falls into this category. The only thing
you probably shouldn't do is rely on it always being there, so have
some catch-all set of headers / css if it's not set (mind you, if that
happens you've got a bigger problem on your hands! but it'd stop your
site breaking).

Why are you creating lots of arrays and then using in_array to check
them? Just seems a little pointless in this instance as it gives you
no real benefit - comparing a one element array against a variable is
just... well.. comparing a variable with a variable! So why not do
that? Perhaps a switch block would serve your needs better?
switch ($_SERVER['HTTP_HOST'])
{
case 'name1.host.com':
$header = ..
break;
}
etc - then you can combine multiple hosts into one section and have a
default set at the bottom.
Best regards,
Richard Davey
