Hi,

DatePeriod name is a bit confusing no ?

dateperiod in php has an interval (btw many results should be fetched).

Example:

$start = new \DateTime('2012-02-25 00:00:00');
$end  = new \DateTime('2012-04-01 00:00:00');
$interval = new \DateInterval('P1D');
$datePeriod = new \DatePeriod($start, $interval, $end);

$count = $bitter
    ->bitDatePeriod('active', 'active_period_example', $datePeriod)
    ->count('active_period_example')
;

$count should return an array with results by day.

Actual feature of period should imo be renamed, sorry, i've no term at this moment :s

Or may be having an other argument wich accept a \DateInterval and make the work :) Easier.

Just crappy to have $start, $end, $interval instead of a $datePeriod object.

count method does a redis BITCOUNT on the key. Also, you can call in method to know if an id is in the key.

In Bitter, you have default keys which are by year, by month, by week, by day, by hour. So you can call count and in methods on them. Example: count on July month, on 2012 year, on yesterday.

But in 1.0 you can't do that on a custom date period like count on date period from 2010-02-25 13:00:00 to 2012-12-24 10:00:00. Now in 1.1 you can with bitDatePeriod.

Your feature is more like an detail of a given date period. Example: I want to know how many user where active each day of December, or each month of 2012, or each hour of yesterday. I think it's a good idea to implement it too. :+1:

That's what i said ;) A DatePeriod in php does not represent ONLY from date -> to date, a DatePeriod has an interval too.

• bitDatePeriod needs to be renamed into bitDateRange as it looks confusing ATM
• A new method needs to be introduced, something like countByPeriodWithInterval(\DateTime $from, \DateTime $to, \DateInterval $interval). This method should return an array or any iterable object collection.
