php - add two hours to date variable
提问by laarsk
I want to add 3 minutes to a date/time variable I have, but I'm not sure how to do this. I made the variable from a string like this: (which is in the RFC 2822 date format btw)
我想为我拥有的日期/时间变量添加 3 分钟，但我不确定如何执行此操作。我从这样的字符串中创建了变量：（顺便说一句，它采用 RFC 2822 日期格式）
$date = 2011-10-18T19:56:00+0200
I converted that string into date using this command:
我使用以下命令将该字符串转换为日期：
$time = date_format(DateTime::createFromFormat("Y-m-d\TH:i:sO", $date), "G:i")
Now, I'd like to add 3 minutes to that variable, but I I'm not sure how. I've used the following command in my script before, but that applies to the current date/time, so I'm not sure how to use that for my time variable:
现在，我想为该变量添加 3 分钟，但我不确定如何。我之前在脚本中使用过以下命令，但这适用于当前日期/时间，所以我不确定如何将它用于我的时间变量：
$currenttime = date('G:i', strtotime('+2 hours'));
So, how can I add three minutes to the $time variable?
那么，如何在 $time 变量中添加三分钟呢？

echo $idate="2013-09-25 09:29:44";
$effectiveDate = strtotime("+40 minutes", strtotime($idate));
echo date("Y-m-d h:i:s",$effectiveDate);

Since you're using the DateTime object already, stick with it:
由于您已经在使用 DateTime 对象，请坚持使用它：
$time = DateTime::createFromFormat("Y-m-d\TH:i:sO", $date);
$three_minutes = $time->add(new DateInterval('P2H'));
^^--two (2) hours (H)

The format starts with the letter P, for "period." Each duration period is represented by an integer value followed by a period designator. If the duration contains time elements, that portion of the specification is preceded by the letter T.
格式以字母 P 开头，表示“句点”。每个持续时间段由一个整数值表示，后跟一个时间段指示符。如果持续时间包含时间元素，则规范的该部分前面有字母 T。

That being said my solution to a similar problem is this:
话虽如此，我对类似问题的解决方案是这样的：
// pretend that $date is what you got from mysql
// which is like 2013-02-12 23:08:17
echo "<br>";
echo $date;
$time = DateTime::createFromFormat("Y-m-d H:i:s", $date);
echo "<br>";
echo $time->format('H-i-s');
$time->add(new DateInterval('PT2H'));
echo "<br>";
echo $time->format('H-i-s');
// Outputs:
// 2013-02-12 23:08:17
// 23-08-17
// 01-08-17
The thing is to add Pwhen using DateIntervalclass, and Tbefore time entries. For your case you need to go with PT3Mfor 3 minute addition. I was trying to add 2 hours and what I did was $time->add(new DateInterval('PT2H'));.
问题是P在使用DateInterval类时和T时间条目之前添加。对于您的情况，您需要PT3M添加 3 分钟。我试图增加 2 小时，而我所做的是$time->add(new DateInterval('PT2H'));.
If you would look at the interval specs:
如果您查看间隔规格：
Y years
M months
D days
W weeks. These get converted into days, so can not be combined with D.
H hours
M minutes
S seconds
Mfor monthsand Mfor minutes. That is why there is a Tin front of time.
M为months和M为minutes。这就是为什么有一个T前面的时间。
At least that's what I want to believe... 'O_O
至少这就是我想相信的......'O_O

//set the date and time
$start = '2017-01-01 14:00:00';
//display the converted time you want to add for ex. 1 hour and 20 minutes
echo date('Y-m-d H:i:s',strtotime('+1 hour +20 minutes',strtotime($start)));
