How to sum N number of time (HH:MM Format)?
this should do what you are looking for:
$times
is the array of times and you can add how many time you want
$times = array();
$times[] = "12:59";
$times[] = "0:58";
$times[] = "0:02";
// pass the array to the function
echo AddPlayTime($times);
function AddPlayTime($times) {
$minutes = 0; //declare minutes either it gives Notice: Undefined variable
// loop throught all the times
foreach ($times as $time) {
list($hour, $minute) = explode(':', $time);
$minutes += $hour * 60;
$minutes += $minute;
}
$hours = floor($minutes / 60);
$minutes -= $hours * 60;
// returns the time already formatted
return sprintf('%02d:%02d', $hours, $minutes);
}
EDIT
I edited the code with the right names of the variables. It is more correct now.
hope this helps :-)
Here is an function that will sum all your time values in format HH:MM
:
function sum_time() {
$i = 0;
foreach (func_get_args() as $time) {
sscanf($time, '%d:%d', $hour, $min);
$i += $hour * 60 + $min;
}
if ($h = floor($i / 60)) {
$i %= 60;
}
return sprintf('%02d:%02d', $h, $i);
}
// use example
echo sum_time('01:05', '00:02', '05:59'); # 07:06
