Ah, I forgot to point that out in my previous note:
> "Constants may only evaluate to scalar values."
Currently, resources are "abstract datatypes based on integers".
Though this may change in the future, and is_scalar() rejects resources as non-scalar, you can
define resource constants, like
<?php define('DB', mysql_connect());?>
(think of STDIN, STDOUT and STDERR).
Resource constants will still remain resources; try var_dump().
