I'd just try and avoid the hyphens in the variable names in the first
place if you can. Can you guarantee that everyone working on this system
will know when to encapsulate the variables in braces?
Thanks,

Agreed.
>From http://www.php.net/manual/en/language.variables.basics.php :
"Variable names follow the same rules as other labels in PHP. A
valid variable name starts with a letter or underscore, followed
by any number of letters, numbers, or underscores."
The ${var} circumvents this (somewhat), but in the case above, it
would be better to avoid the dashes and use underscores.

There are certain times I'd like to include all files in a given
directory (such as configuration stuff that is split out by type, a la
apache conf.d). Anyone have something handy that implements that?
