Answer 1

I've had several issues handling time in php.

The best way I've ever found it was this (and that way even if your calculation goes through 24 hours will not generate problems).

<?php

function time_to_sec($time) {
list($h, $m, $s) = explode (":", $time);
$seconds = 0;
$seconds += (intval($h) * 3600);
$seconds += (intval($m) * 60);
$seconds += (intval($s));
return $seconds;
}
function sec_to_time($sec) {
return sprintf('%02d:%02d:%02d', floor($sec / 3600), floor($sec / 60 % 60), floor($sec % 60));
}

$time1 = time_to_sec("00:02:00");
$time2 =  time_to_sec("00:15:00");
$time3 = time_to_sec("00:08:00");

$total = $time1 + $time2 + $time3;
var_dump(sec_to_time($total));
?>

I hope I have helped.

You can use like this way. it will work.

$arr = [
    '00:02:00',
    '00:15:00',
    '00:08:00'
    ];
   $hour =0;$min=0;$sec=0;
   foreach($arr as $a){
      $time = explode(':',$a);
      $sec +=$time[2];
      $min +=$time[1];
      $hour += $time[0];
   }
   echo sprintf('%02d',$hour).':'.sprintf('%02d',$min).':'.sprintf('%02d',$sec);

Thanks,

Try this one.This should do what you are looking for:

<?php
/**
 * @param array $times
 * @return string
 */
function sumOfDiffrentTime($times = array())
{
    $minutes = '';
    $seconds = '';
    // loop through all the times array
    foreach ($times as $time) {
        list($hour, $minute, $second) = explode(':', $time);
        $minutes += $hour * 60;
        $minutes += $minute;
        $seconds += (intval($second));
    }
    $hours = floor($minutes / 60);
    $minutes -= $hours * 60;

    // returns the  formatted time
    return sprintf('%02d:%02d:%02d', $hours, $minutes, $seconds);
}

$times = array();

$times[] = "00:02:00";
$times[] = "00:15:00";
$times[] = "00:08:00";

// pass your $times array to the function
echo sumOfDiffrentTime($times);

Change from h into H.

h => 12-hour format of an hour with leading zeros

H => 24-hour format of an hour with leading zeros

Try

echo date('H:i:s', strtotime('00:02:00') + strtotime('00:15:00') + strtotime('00:08:00'));
