Convert seconds into days, hours, minutes and seconds

Question

I would like to convert a variable $uptime which is seconds, into days, hours, minutes and seconds.

Example:

Answer 1

Based on the answer by Julian Moreno, but changed to give the response as a string (not an array), only include the time intervals required and not assume the plural.

The difference between this and the highest voted answer is:

For 259264 seconds, this code would give

3 days, 1 minute, 4 seconds

For 259264 seconds, the highest voted answer (by Glavić) would give

3 days, 0 hours, 1 minutes and 4 seconds

function secondsToTime($inputSeconds) {
    $secondsInAMinute = 60;
    $secondsInAnHour = 60 * $secondsInAMinute;
    $secondsInADay = 24 * $secondsInAnHour;

    // Extract days
    $days = floor($inputSeconds / $secondsInADay);

    // Extract hours
    $hourSeconds = $inputSeconds % $secondsInADay;
    $hours = floor($hourSeconds / $secondsInAnHour);

    // Extract minutes
    $minuteSeconds = $hourSeconds % $secondsInAnHour;
    $minutes = floor($minuteSeconds / $secondsInAMinute);

    // Extract the remaining seconds
    $remainingSeconds = $minuteSeconds % $secondsInAMinute;
    $seconds = ceil($remainingSeconds);

    // Format and return
    $timeParts = [];
    $sections = [
        'day' => (int)$days,
        'hour' => (int)$hours,
        'minute' => (int)$minutes,
        'second' => (int)$seconds,
    ];

    foreach ($sections as $name => $value){
        if ($value > 0){
            $timeParts[] = $value. ' '.$name.($value == 1 ? '' : 's');
        }
    }

    return implode(', ', $timeParts);
}

I hope this helps someone.

Answer 2

function convert($seconds){
$string = "";

$days = intval(intval($seconds) / (3600*24));
$hours = (intval($seconds) / 3600) % 24;
$minutes = (intval($seconds) / 60) % 60;
$seconds = (intval($seconds)) % 60;

if($days> 0){
    $string .= "$days days ";
}
if($hours > 0){
    $string .= "$hours hours ";
}
if($minutes > 0){
    $string .= "$minutes minutes ";
}
if ($seconds > 0){
    $string .= "$seconds seconds";
}

return $string;
}

echo convert(3744000);

Here's some code that I like to use for the purpose of getting the duration between two dates. It accepts two dates and gives you a nice sentence structured reply.

This is a slightly modified version of the code found here.

<?php

function dateDiff($time1, $time2, $precision = 6, $offset = false) {

    // If not numeric then convert texts to unix timestamps

    if (!is_int($time1)) {
            $time1 = strtotime($time1);
    }

    if (!is_int($time2)) {
            if (!$offset) {
                    $time2 = strtotime($time2);
            }
            else {
                    $time2 = strtotime($time2) - $offset;
            }
    }

    // If time1 is bigger than time2
    // Then swap time1 and time2

    if ($time1 > $time2) {
            $ttime = $time1;
            $time1 = $time2;
            $time2 = $ttime;
    }

    // Set up intervals and diffs arrays

    $intervals = array(
            'year',
            'month',
            'day',
            'hour',
            'minute',
            'second'
    );
    $diffs = array();

    // Loop thru all intervals

    foreach($intervals as $interval) {

            // Create temp time from time1 and interval

            $ttime = strtotime('+1 ' . $interval, $time1);

            // Set initial values

            $add = 1;
            $looped = 0;

            // Loop until temp time is smaller than time2

            while ($time2 >= $ttime) {

                    // Create new temp time from time1 and interval

                    $add++;
                    $ttime = strtotime("+" . $add . " " . $interval, $time1);
                    $looped++;
            }

            $time1 = strtotime("+" . $looped . " " . $interval, $time1);
            $diffs[$interval] = $looped;
    }

    $count = 0;
    $times = array();

    // Loop thru all diffs

    foreach($diffs as $interval => $value) {

            // Break if we have needed precission

            if ($count >= $precision) {
                    break;
            }

            // Add value and interval
            // if value is bigger than 0

            if ($value > 0) {

                    // Add s if value is not 1

                    if ($value != 1) {
                            $interval.= "s";
                    }

                    // Add value and interval to times array

                    $times[] = $value . " " . $interval;
                    $count++;
            }
    }

    if (!empty($times)) {

            // Return string with times

            return implode(", ", $times);
    }
    else {

            // Return 0 Seconds

    }

    return '0 Seconds';
}

Answer 4

This is a function i used in the past for substracting a date from another one related with your question, my principe was to get how many days, hours minutes and seconds has left until a product has expired :

$expirationDate = strtotime("2015-01-12 20:08:23");
$toDay = strtotime(date('Y-m-d H:i:s'));
$difference = abs($toDay - $expirationDate);
$days = floor($difference / 86400);
$hours = floor(($difference - $days * 86400) / 3600);
$minutes = floor(($difference - $days * 86400 - $hours * 3600) / 60);
$seconds = floor($difference - $days * 86400 - $hours * 3600 - $minutes * 60);

echo "{$days} days {$hours} hours {$minutes} minutes {$seconds} seconds";

Answer 5

Here it is a simple 8-lines PHP function that converts a number of seconds into a human readable string including number of months for large amounts of seconds:

PHP function seconds2human()

function seconds2human($ss) {
$s = $ss%60;
$m = floor(($ss%3600)/60);
$h = floor(($ss%86400)/3600);
$d = floor(($ss%2592000)/86400);
$M = floor($ss/2592000);

return "$M months, $d days, $h hours, $m minutes, $s seconds";
}

Answer 6

There are some very good answers here but none of them covered my needs. I built on Glavic's answer to add some extra features that I needed;

• Don't print zeros. So "5 minutes" instead of " 0 hours, 5 minutes"
• Handle plural properly instead of defaulting to the plural form.
• Limit the output to a set number of units; So "2 months, 2 days" instead of "2 months, 2 days, 1 hour, 45 minutes"

You can see a running version of the code here.

function secondsToHumanReadable(int $seconds, int $requiredParts = null)
{
    $from     = new \DateTime('@0');
    $to       = new \DateTime("@$seconds");
    $interval = $from->diff($to);
    $str      = '';

    $parts = [
        'y' => 'year',
        'm' => 'month',
        'd' => 'day',
        'h' => 'hour',
        'i' => 'minute',
        's' => 'second',
    ];

    $includedParts = 0;

    foreach ($parts as $key => $text) {
        if ($requiredParts && $includedParts >= $requiredParts) {
            break;
        }

        $currentPart = $interval->{$key};

        if (empty($currentPart)) {
            continue;
        }

        if (!empty($str)) {
            $str .= ', ';
        }

        $str .= sprintf('%d %s', $currentPart, $text);

        if ($currentPart > 1) {
            // handle plural
            $str .= 's';
        }

        $includedParts++;
    }

    return $str;
}
