PHP查找两个日期时间之间的差异 [英] PHP find difference between two datetimes

问题描述

我正在尝试获取两个日期时间之间的差异并将其作为 datetime 返回.我找到了使用 diff 的例子，但我似乎做对了.

I'm trying to get the difference between two datetimes and return it as a datetime. I've found examples using diff but I can't seem to get it right.

$timein = date("Y-m-d H:i:s");
$timeout = date("Y-m-d 20:00:00");
$totaltime = $timein->diff($timeout);

但是 $totaltime 将 0000-00-00 00:00:00 记录到我的数据库中.这是因为我没有格式化我的 totaltime 变量吗?

However $totaltime logs 0000-00-00 00:00:00 to my DB. Is this because I'm not formatting my totaltime variable?

推荐答案

我不确定您在寻找什么格式的差异，但这里是使用 DateTime 的方法

I'm not sure what format you're looking for in your difference but here's how to do it using DateTime

$datetime1 = new DateTime();
$datetime2 = new DateTime('2011-01-03 17:13:00');
$interval = $datetime1->diff($datetime2);
$elapsed = $interval->format('%y years %m months %a days %h hours %i minutes %s seconds');
echo $elapsed;
