I am trying to create an elapsed time using date_purchased from a database table called order. I know I am getting the date_purchased as I can

<?php echo zen_datetime_short($order->info['date_purchased']); ?>

and get the date and time formatted as 04/20/2014 11:19:56 I'm not good with php and am just starting to learn this but from what I have researched I have tried the following

<?php
$first  = $order->info['date_purchased'];
$second = new DateTime( 'Y-m-d H:i:s' );
$diff = $first->diff( $second );
?>

Then I do 

<?php echo $diff->format( '%H:%I:%S' ); ?>

Unfortunately the page loads up until my echo and then everything that should appear below it doesn't. I preferably would only want to show minutes and seconds on my output.

Thanks for your help. I'm using php 5.3 on my server.

     $dt = date('Y-m-d H:i:s');
     echo $dt."<br>";

     $difference = strtotime($dt) - strtotime("20-04-2014 20:14:30");

    // getting the difference in minutes
     $difference_in_hours = $difference / (60*60);

     echo $difference_in_hours."<br>";

    function sECONDS_TO_DHMS($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_DHMS($difference);

用您从数据库中获取的日期时间替换第二个时间字段。

我对 zen-cart 不太熟悉，但根据文档，zen_datetime_short似乎将原始字符串作为参数。

什么（我认为）这意味着您正在尝试将字符串用作 PHPDateTime对象，这将导致您的脚本失败。您可以尝试修改脚本以将数据库中的原始时间戳转换为DateTime对象，如下所示，并查看是否有更好的结果：

$first  = new DateTime($order->info['date_purchased']);
$second = new DateTime();
$diff   = $first->diff($second);

echo $diff->format('%H:%I:%S') . "\n";
