How to calculate time diferences PHP? [closed]

I have this data: $t1 = ’75:00′; //Corresponds to Hours:Minutes $t2 = ’05:13′;

// I need to know the time diference in this example must return: ’69:47′

Answer

75:00 is not a valid time, but if you found yourself in a situation that you have to use that, use this code below

<?php


function convertToMinutes($time)
{

    list($hour, $minutes) = explode(":", $time);
    $hoursToMinutes = $hour * 60;
    $addMinutes = $hoursToMinutes + $minutes;
    return $addMinutes;
}

function convertToHours($time)
{
    $hours = floor($time / 60);
    $minutes = $time % 60;

    if ($time < 60) {
        return $time;
    }
    return $hours . ":" . $minutes;
}

function timeDifference($time1, $time2)
{
    if ($time1 >= $time2) {
        $diff = convertToMinutes($time1) - convertToMinutes($time2);

        return convertToHours($diff);
    }
    $diff = convertToMinutes($time2) - convertToMinutes($time1);
    return convertToHours($diff);
}

$t1 = '75:00';
$t2 = '05:13';

$answer = timeDifference($t1, $t2);

echo $answer;
