Time calculation between 2 dates

@Dave friend you are right, but your option would also be wrong if it is more than a month.

An excellent point!

This revised code handles that.

PHP Code:

$start = new DateTime("2017-03-09 09:26:00");
$end = new DateTime("2017-04-09 09:26:00");
$interval = $start->diff($end);
$hrs = $interval->days * 24 + $interval->h;
echo $hrs." hours ".$interval->format('%i')." minutes";
