请问php中两个时间如何相减?
有一个已知时间格式为2012-11-22 12:05:07 我想用现在时间格式为:2012-11-23 16:13:08减去第一个时间,即用2012-11-23 16:13:08减去2012-11-22 12:05:07得出已用时间1天4小时8分1秒。
------解决方案--------------------
$time = time()-strtotime('2012-11-22 12:00:00');
$yourday = (int)($time/(3600*24));
$yourhour = (int)(($time%(3600*24))/(3600));
$yourmin = (int)($time%(3600)/60);
echo $yourday.'天'.$yourhour.'小时'.$yourmin.'分';
//1天4小时34分
------解决方案--------------------
$datetime1 = new DateTime('2012-11-23 16:13:08');<br /> $datetime2 = new DateTime('2012-11-22 12:05:07');<br /> $interval = $datetime1->diff($datetime2);<br /> echo $interval->format('%d天%H小时%i分%s秒');<br />
