I'd probably do this with a regex plus a quick test for in-range values -- something like
(untested):
if ($number>0 && $number<24
&& preg_match('^[0-9]{1-2}(\.[0-9]{1,2})?$', $number))
do_stuff;
You could also tweak the regex to filter out out-of-range values and dispense with the range checks
-- something like (again untested):
if (preg_match('^(1?[0-9]|2[0-4])(\.[0-9]{1,2})?$', $number))
do_stuff;
Cheers!
Mike
