Answer 1

you can do like this:

$start1 = date_create('05:16');
$end1 = date_create('08:48');
$diff1=date_diff($end1,$start1);
$time1=$diff1->format("%h:%i");
echo $time1; //3 Hours 32 mintues

$start2 = date_create('05:16');
$end2 = date_create('08:48');
$diff2=date_diff($end2,$start2);
$time2=$diff2->format("%h:%i");
echo $time2; //1 Hours 32 mintues

$secs = strtotime($time1)-strtotime("00:00:00");
$hours = date("H",strtotime($time2)+$secs);
$minutes = date("i",strtotime($time2)+$secs);
$final_time=$hours." Hours ".$minutes." Minutes";
echo $final_time;
