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

foreach ($email as $temp => $value) {
    $dat = strtotime($value['subscription_expiration']); //$value come from mysql database
//$email is an array from mysqli_query()
    $date = strtotime(date('Y-m-d'));

    $_SESSION['expiry'] = (((($dat - $date)/60)/60)/24)." Days Left";
//you will get the difference from current date in days.
}

$value come from Database. This code is in Codeigniter. $SESSION is used for storing user subscriptions. it is mandatory. I used it in my case, you can use whatever you want.

Answer 2

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 3

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 4

Interval class I have written can be used. It can be used in opposite way too.

composer require lubos/cakephp-interval

$Interval = new \Interval\Interval\Interval();

// output 2w 6h
echo $Interval->toHuman((2 * 5 * 8 + 6) * 3600);

// output 36000
echo $Interval->toSeconds('1d 2h');

Answer 5

gmdate("d H:i:s",1640467);

Result will be 19 23:41:07. When it is just one second more than normal day, it is increasing the day value for 1 day. This is why it show 19. You can explode the result for your needs and fix this.

Answer 6

an extended version of Glavić's excellent solution , having integer validation, solving the 1 s problem, and additional support for years and months, at the expense of being less computer parsing friendly in favor of being more human friendly:

<?php
function secondsToHumanReadable(/*int*/ $seconds)/*: string*/ {
    //if you dont need php5 support, just remove the is_int check and make the input argument type int.
    if(!\is_int($seconds)){
        throw new \InvalidArgumentException('Argument 1 passed to secondsToHumanReadable() must be of the type int, '.\gettype($seconds).' given');
    }
    $dtF = new \DateTime ( '@0' );
    $dtT = new \DateTime ( "@$seconds" );
    $ret = '';
    if ($seconds === 0) {
        // special case
        return '0 seconds';
    }
    $diff = $dtF->diff ( $dtT );
    foreach ( array (
            'y' => 'year',
            'm' => 'month',
            'd' => 'day',
            'h' => 'hour',
            'i' => 'minute',
            's' => 'second' 
    ) as $time => $timename ) {
        if ($diff->$time !== 0) {
            $ret .= $diff->$time . ' ' . $timename;
            if ($diff->$time !== 1 && $diff->$time !== -1 ) {
                $ret .= 's';
            }
            $ret .= ' ';
        }
    }
    return substr ( $ret, 0, - 1 );
}

var_dump(secondsToHumanReadable(1*60*60*2+1)); -> string(16) "2 hours 1 second"
