RE: [PHP] Re: Numerical Recipe - Scheduling Question - update...
logic/restrictions/implementation...
user selects every 'day' (mtwthf)
covered by the weekly section.. (no need for a separate selection)
user selects 1st of month
covered by the monthly section (no need for a separate selection)
user selects 'last-of-month'
user selects 'X' as the numeric interval
(if 'X' is blank, app defaults 'X' to 1)
app gets the startime in linuxsecs, based on user input, or 'default
now()'
app determines the month based on the computed secs data
app app then detemines the last date of the computed month
app uses date(-t,secs) to get date...
app gets year:month hour:min from the startime/linuxsecs
use the date, and the year:month and hour:min to get the
final eventsecs for the last-of-month

This is confusing. When and where do you need to be able to determine
when the future events/occurances are? You need to display this after
the user schedules the app/process or an admin needs to login and see
this at any given time?
Regardless it is easy with the PHP time/date functions. Once you've
collected and stored the start/stop times and interval, something
similar to:
$interval = 1 week;
$next = $start_time;
while ($next = $end_time) {
$next = strtotime(+$interval, $next);
echo date(DATE_RFC822, $next) .\n;
}

RE: [PHP] Re: Numerical Recipe - Scheduling Question
hey shawn...
strtotime (or something similar) might just work
i'll always know the interval... which can be used to compute the nexttime,
which then becomes the next starttime...
i'm assuming there's an equally simple way to find the last day of a given
month if i choose that as an interval as well..
for my initial needs.. this might work.. until i free up time to actually
craft a more generic solution, independent of the underlying language/os..
thanks
for next month.. and the start

RE: [PHP] Re: Numerical Recipe - Scheduling Question
hey shawn...
on the strtotime function... it appears to simply take intervals of a string
type..
is there a way to have it take intervals of the number of secs? or is there
another time function that takes the current date/time, and allows you to
add an interval in secs?
thanks

If you search, there are 100s of ways to do these types of things.
Check the date/time functions. There are many and many ways to use
theme. Here is one:
date('t', strtotime($year-$month-01));
for my initial needs.. this might work.. until i free up time to actually
craft a more generic solution, independent of the underlying language/os..
