Convert seconds into days, hours, minutes and seco

Question

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

Example:

$uptime = 1640467;

Result should be:

18 days 23 hours 41 minutes

Answer 1

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);

Answer 2

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;
}

Answer 3

The simplest approach would be to create a method that returns a DateInterval from the DateTime::diff of the relative time in $seconds from the current time $now which you can then chain and format. For example:-

public function toDateInterval($seconds) {
    return date_create('@' . (($now = time()) + $seconds))->diff(date_create('@' . $now));
}

Now chain your method call to DateInterval::format

echo $this->toDateInterval(1640467)->format('%a days %h hours %i minutes'));

Result:

18 days 23 hours 41 minutes

Answer 4

This is the function rewritten to include days. I also changed the variable names to make the code easier to understand...

/** 
 * Convert number of seconds into hours, minutes and seconds 
 * and return an array containing those values 
 * 
 * @param integer $inputSeconds Number of seconds to parse 
 * @return array 
 */ 

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);

    // return the final array
    $obj = array(
        'd' => (int) $days,
        'h' => (int) $hours,
        'm' => (int) $minutes,
        's' => (int) $seconds,
    );
    return $obj;
}

Answer 5

Although it is quite old question - one may find these useful (not written to be fast):

function d_h_m_s__string1($seconds)
{
    $ret = '';
    $divs = array(86400, 3600, 60, 1);

    for ($d = 0; $d < 4; $d++)
    {
        $q = (int)($seconds / $divs[$d]);
        $r = $seconds % $divs[$d];
        $ret .= sprintf("%d%s", $q, substr('dhms', $d, 1));
        $seconds = $r;
    }

    return $ret;
}

function d_h_m_s__string2($seconds)
{
    if ($seconds == 0) return '0s';

    $can_print = false; // to skip 0d, 0d0m ....
    $ret = '';
    $divs = array(86400, 3600, 60, 1);

    for ($d = 0; $d < 4; $d++)
    {
        $q = (int)($seconds / $divs[$d]);
        $r = $seconds % $divs[$d];
        if ($q != 0) $can_print = true;
        if ($can_print) $ret .= sprintf("%d%s", $q, substr('dhms', $d, 1));
        $seconds = $r;
    }

    return $ret;
}

function d_h_m_s__array($seconds)
{
    $ret = array();

    $divs = array(86400, 3600, 60, 1);

    for ($d = 0; $d < 4; $d++)
    {
        $q = $seconds / $divs[$d];
        $r = $seconds % $divs[$d];
        $ret[substr('dhms', $d, 1)] = $q;

        $seconds = $r;
    }

    return $ret;
}

echo d_h_m_s__string1(0*86400+21*3600+57*60+13) . "\n";
echo d_h_m_s__string2(0*86400+21*3600+57*60+13) . "\n";

$ret = d_h_m_s__array(9*86400+21*3600+57*60+13);
printf("%dd%dh%dm%ds\n", $ret['d'], $ret['h'], $ret['m'], $ret['s']);

result:

0d21h57m13s
21h57m13s
9d21h57m13s

Answer 6

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";
