Time difference between php timestamps in hours

I have a php timestamp 1331875634

generated using a php function time()

.

I have a current timestamp generated using the same function.

<?php
$time1 = "1331875634";
$time2 = time();

echo $differencem; //time difference in minutes
echo $differenceh; //time difference in hours
?>

I want to know the difference between these two in minutes. Minutes can be divided by 60 to do this in hours.

You get the difference in seconds if you subtract them, so divide by 60 to get minutes and another 60 to get hours.

I created this code to take the standard PHP UNIX TIMESTAMP, calculate the time difference, and return the standard time or custom time format. This is great for timing a project and calculating the time it takes to get results.



function timerFormat($start_time, $end_time, $std_format = false)
{       
$total_time = $end_time - $start_time;
$days       = floor($total_time /86400);        
$hours      = floor($total_time /3600);     
$minutes    = intval(($total_time/60) % 60);        
$seconds    = intval($total_time % 60);     
$results = "";
if($std_format == false)
{
  if($days > 0) $results .= $days . (($days > 1)?" days ":" day ");     
  if($hours > 0) $results .= $hours . (($hours > 1)?" hours ":" hour ");        
  if($minutes > 0) $results .= $minutes . (($minutes > 1)?" minutes ":" minute ");
  if($seconds > 0) $results .= $seconds . (($seconds > 1)?" seconds ":" second ");
}
else
{
  if($days > 0) $results = $days . (($days > 1)?" days ":" day ");
  $results = sprintf("%s%02d:%02d:%02d",$results,$hours,$minutes,$seconds);
}
return $results;
}

Example:

$begin_routine_time = time();
echo(timerFormat($begin_routine_time, $time()));

$datetime1 = new DateTime(date('Y-m-d H:i:s', 1331875634));
$datetime2 = new DateTime(date('Y-m-d H:i:s'));
$oDiff = $datetime1->diff($datetime2);
echo $oDiff->y.' Years <br/>';
echo $oDiff->m.' Months <br/>';
echo $oDiff->d.' Days <br/>';
echo $oDiff->h.' Hours <br/>';
echo $oDiff->i.' Minutes <br/>';
echo $oDiff->s.' Seconds <br/>';

Somehow I needed to convert seconds to time like 1 day 03:34:13 days: minuts: secondes

I wrote this function

function sECONDS_TO_HMS($seconds)
  {

     $days = floor($seconds/86400);
     $hrs = floor($seconds/3600);
     $mins = intval(($seconds / 60) % 60); 
     $sec = intval($seconds % 60);

        if($days>0){
          //echo $days;exit;
          $hrs = str_pad($hrs,2,'0',STR_PAD_LEFT);
          $hours=$hrs-($days*24);
          $return_days = $days." Days ";
          $hrs = str_pad($hours,2,'0',STR_PAD_LEFT);
     }else{
      $return_days="";
      $hrs = str_pad($hrs,2,'0',STR_PAD_LEFT);
     }

     $mins = str_pad($mins,2,'0',STR_PAD_LEFT);
     $sec = str_pad($sec,2,'0',STR_PAD_LEFT);

     return $return_days.$hrs.":".$mins.":".$sec;
  }

echo sECONDS_TO_HMS(65); // 00:01:05
echo sECONDS_TO_HMS(76325); //21:12:05
echo sECONDS_TO_HMS(345872); // 4 Days 00:04:32

I think this might be helpful for you.
