在php和laravel 24H中减去两次

Question

This seems like a fairly simple question, but I'm having trouble with it! In my request, I have two fields

$takeOffTime = '23:00';
$landingTime = '01:05';

I want to subtract breakout from break in to get the difference, and then take that number and subtract it from the difference between takeOffTime and landingTime.

How can I do this in 24H formt 'h:i '?

$takeOff = '23:00';
$landing = '01:10';

$t1 = strtotime($takeOff);
$t2 = strtotime($landing);

Answer 1

You can subtract two times to H:i format like this.

$takeOff = '23:00';
$landing = '01:10';

$t1 = strtotime($takeOff);
$t2 = strtotime($landing);

$diff = gmdate('H:i', $t2 - $t1);

dd($diff); // "02:10"

Answer 2

With DateTime diff you can calculate the DateInterval, then format the DateInterval with format,

$takeOff = '23:00';
$landing = '01:05';
$take_off_date = new DateTime('23:00');
$landing_date = new DateTime('01:05');
if($landing <= $takeOff){
    $landing_date->add(new DateInterval("P1D"));
}
echo ($landing_date->diff($take_off_date))->format("%H:%I");

output 02:05
