How to do this in PHP?

Not sure if any of you will know but how do I do what <!--#echo
var="HTTP_HOST" --> does in a .shtml in .php?

$HTTP_HOST requires the register globals configuration option to be set
and this has been deprecated for some time now, although it will still
be enabled on most hosts to prevent older scripts being broken.

the $_SERVER and other arrays were introduced to avoid some security
issues and are the "proper" way of doing things.

<? echo $_SERVER["HTTP_HOST"] ?>

Yes. Some older installations of PHP set things up so the $_SERVER, $_COOKIE,
$_GET and $_POST arrays get extracted to scalar variables. However, this may
cause some security issues so newer PHP versions default to having it off,
which I believe to be a good idea. To be safe, use the method described by
Chris and myself. Otherwise $HTTP_HOST might be undefined.

What's the difference between "print" and "echo" as used in php?
