试试这个：

减去时间：（小时加分钟）

function subtractTime($initialHour, $finalHour){
  return (date("H:i", strtotime("00:00") + strtotime($finalHour) - strtotime($initialHour)));
}

减去时间：（小时加上分钟和秒）

function subtractTime($initialHour, $finalHour){
  return (date("H:i:s", strtotime("00:00:00") + strtotime($finalHour) - strtotime($initialHour)));
}

求和时间：

function sumTime($initialHour, $finalHour) {
  $h = date('H', strtotime($finalHour));
  $m = date('i', strtotime($finalHour));
  $s = date('s', strtotime($finalHour));
  $tmp = $h." hour ".$m." min ".$s." second";
  $sumHour = $initialHour." + ".$tmp;
  $newTime = date('H:i:s', strtotime($sumHour));
  return $newTime;
}

看看DateTime::diff或strtotime

继承人的东西可能会有所帮助

$future = strtotime('21 July 2013');
$timefromdb = //source time you have to define
$timeleft = $future-$timefromdb;
$daysleft = round((($timeleft/24)/60)/60);

function timeToMinutes($time) {
$time = explode(':', $time);

return (($time[2]=='pm')?($time[0]+12):$time[0])*60+$time[1];
}

$diff = timeToMinutes('10:11:pm') - timeToMinutes('12:10:am');

echo $diff; //difference in minutes
