carbon convert minutes to seconds laravel code example

Example 1: add seconds to datetime carbon

Try to parse() it first:
$date = Carbon::parse($dateTime)
            ->addSeconds($seconds)
            ->format('Y-m-d H:i:s');

Example 2: change minutes in to hours carbon

You can use:
----------------
$minutes = 1510;
$hours = intdiv($minutes, 60).':'. ($minutes % 60);
!!! This only works with php >= v7.xx

Previous answer:
-------------------
$minutes = 1510;
$hours = floor($minutes / 60).':'.($minutes - floor($minutes / 60) * 60);
