PHP添加时间 [英] PHP add time to date

问题描述

我有一个php时间 09:00，我想将其设置为日期时间。

I have a php time "09:00" that I want to set as the time for a date.

$date="2016-08-21 00:00:00.000000";
$time="09:00";

所以理想地：

$datetime=$date+$time;//<----------what is the function for this
echo $datetime;

给出 2016-08-21 09：00：00.000000

gives "2016-08-21 09:00:00.000000"

或

$date="2016-08-21 00:00:00.000000";
$time="17:30";

然后

$datetime=$date+$time;//<----------what is the function for this
echo $datetime;

给出 2016-08-21 17：30：00.000000。
一个看似简单的要求，我找不到解决方案。

gives "2016-08-21 17:30:00.000000". A seemingly simple requirement I cannot find a solution to.

推荐答案

正在添加答案的马克这就是我所拥有的但是似乎很笨拙-我希望有更好的方法：

Pending Mark adding an answer this was what I had but it seems clumsy - I hoped there was a better way:

 $timebits = explode(":", $timepart);
 $now->setTime($timebits[0], $timebits[1], $timebits[2]);
