php - How is the best way to check iteration between two hours? -

i check how iteration between 2 dates interval 30 minutes.

i have example:

$one = new datetime('2012-01-20 06:00'); $two = new datetime('2012-01-20 17:30'); $first = $one->format('h:i'); $second = $two->format('h:i'); $interval = 30;

in illustration $iteration = 23, how can calculate this?

you split amount of minutes between datetimes desired interval.

$one = strtotime('2012-01-20 06:00'); $two = strtotime('2012-01-20 17:30'); $interval = 30; echo round(($two - $one) / ($interval * 60));

(i've taken shortcut , divided amount of seconds amount of seconds in 30 minutes)
