You can probably do this with some kind of list comprehension, but I
recommend against it, if this has come from a web form. You do NOT
want end users having the power to set variables. Keep it in a
separate object (such as 'form') such that you must always be explicit
about fetching form data. PHP has learned the risks; here's a decent
summary:
