Calculate difference between 2 times in hours in PHP

Question

I have two times - For eg- the current time - 08:24 and date is 02/01/2013 in dd/mm/yyyy format and I have another time at 13:46 and date is 31/12/2012 . So, how can I cal

Answer 1

Another way is to use PHP's date-related classes. The example below uses DateTime::diff() to get a DateInterval object ($interval). It then uses the interval's properties to arrive at the total number of hours in the interval.

$a = DateTime::createFromFormat('H:i d/m/Y', '08:24 02/01/2013');
$b = DateTime::createFromFormat('H:i d/m/Y', '13:46 31/12/2012');

$interval = $a->diff($b);
$hours    = ($interval->days * 24) + $interval->h
          + ($interval->i / 60) + ($interval->s / 3600);

var_dump($hours); // float(42.633333333333)

Answer 2

I got a simple solution, Try this one -

echo getTimeDiff("10:30","11:10");

function getTimeDiff($dtime,$atime)
    {
        $nextDay = $dtime>$atime?1:0;
        $dep = explode(':',$dtime);
        $arr = explode(':',$atime);
        $diff = abs(mktime($dep[0],$dep[1],0,date('n'),date('j'),date('y'))-mktime($arr[0],$arr[1],0,date('n'),date('j')+$nextDay,date('y')));
        $hours = floor($diff/(60*60));
        $mins = floor(($diff-($hours*60*60))/(60));
        $secs = floor(($diff-(($hours*60*60)+($mins*60))));
        if(strlen($hours)<2){$hours="0".$hours;}
        if(strlen($mins)<2){$mins="0".$mins;}
        if(strlen($secs)<2){$secs="0".$secs;}
        return $hours.':'.$mins.':'.$secs;
    }

Answer 3

If you have the dates as timestamps (use strtotime if needed), then just subtract them, optionally take the absolute value, then divide to 3600 (number of seconds in an hour). Easy ^_^

Answer 4

Convert them both to timestamp values, and then subtract to get the difference in seconds.

$ts1 = strtotime(str_replace('/', '-', '02/01/2013 08:24'));
$ts2 = strtotime(str_replace('/', '-', '31/12/2012 13:46'));
$diff = abs($ts1 - $ts2) / 3600;

Answer 5

I found this is simplest way to find time difference, it always works for me

$timestamp1 = strtotime(date('Y-m-d H:i'));
$timestamp2 = strtotime("2020-04-05 18:00");

  $diff = abs($timestamp2 - $timestamp1)/(60*60);
echo $diff;

Answer 6

Just putting this here, for anyone who needs to find the difference between two dates/timestamps in Hours, Minutes 'AND' Seconds!!

$futureDate_raw = '12/13/2018'; // This is your finish date.
$fdate = strtotime($futureDate_raw);

$hours   = (($fdate - time()) / 3600;
$mins    = (($fdate - time()) % 3600) / 60;
$seconds = ((($fdate- time()) % 3600) % 60);
