我有四个字段，使用这些字段显示它们之间的经过时间。 这是我的php代码：
// Days elapsed from the moment of the creation to the date of the visit
$date1 = $ticket->date_at;
$date2 = $ticket->visit_date;
$diff = abs(strtotime($date2) - strtotime($date1));
// Specific time elapsed between the dates, (days, months and years)
$years = floor($diff / (365*60*60*24));
$months = floor(($diff - $years * 365*60*60*24) / (30*60*60*24));
$days = floor(($diff - $years * 365*60*60*24 - $months*30*60*60*24)/ (60*60*24));
// Hours elapsed
$horallamada = strtotime($ticket->time_at);
$horavis = strtotime($ticket->visit_hour_in);
$horasal = strtotime($ticket->visit_hour_out);
$hdiff = $horallamada - $horasal;
$hvisdiff = $horallamada - $horavis;
$hsolution = $horavis - $horasal;
// printing of the time elapsed to answer the ticket
printf("<p>This ticket was answered in ");
echo gmdate("H:i", abs($hvisdiff)); printf(" hours.</p>");
// printing of the time elapsed to solve the ticket
printf("<p>This ticket was solved in ");
echo gmdate("H:i", abs($hsolution)); printf(" hours.</p>");
// total time elapsed calculation
printf("This ticket was closed in %d years, %d months, %d days and \n", $years, $months, $days);
echo gmdate("H:i", abs($hdiff)); printf(" hours after the date of creation.");
$hvisdiff，$hsolution和$hdiff将返回差异为“ 02:36”，即02 小时 和36分钟 分钟 。
如何让它像这样显示？

我尝试了以下this教程，但是，它不起作用。我该如何实现？
