I am creating an event planner and I have a function that consist of hour range. For example I have an event BIRTHDAY and this event is started from 13:15:00 hours to 18:30:00 hours. Now how can I count the hours inside this range?

$end = "18:30:00";

$time = strtotime($start);
$timeStop = strtotime($end);

//how can I count the hours inside?

?>

推荐答案

你可以在这种情况下使用 gmdate() :

You could use gmdate() in this case:

$time = gmdate('H:i:s', $timeStop - $time); // feed seconds
echo $time;

或者也使用 DateTime 类:

$time = new DateTime($start);
$timeStop = new DateTime($end);
$diff = $timeStop->diff($time);
echo $diff->format('%h:%i'); // hours minutes
