(almost) all the tricks are in the comments of the help page for a
function, on php.net
but all functions accept only a given (and usually documented) set of
parameter(type)s, so you'll probably have to prepare the var, or even
call the function in a loop, outputting to yet another descriptively
named array that'll be used as "wanted list" later in the code.
