Adding minutes to date time in PHP
提问by Luke B
I'm really stuck with adding X minutes to a datetime, after doing lots of google'ing and PHP manual reading, I don't seem to be getting anywhere.
我真的坚持将 X 分钟添加到日期时间，在进行了大量的 google'ing 和 PHP 手册阅读之后，我似乎没有任何进展。
The date time format I have is:
我的日期时间格式是：
2011-11-17 05:05: year-month-day hour:minute
2011-11-17 05:05： year-month-day hour:minute
Minutes to add will just be a number between 0 and 59
要添加的分钟数只是 0 到 59 之间的数字
I would like the output to be the same as the input format with the minutes added.
我希望输出与添加分钟的输入格式相同。
Could someone give me a working code example, as my attempts don't seem to be getting me anywhere?
有人可以给我一个有效的代码示例，因为我的尝试似乎并没有让我在任何地方？

$minutes_to_add = 5;
$time = new DateTime('2011-11-17 05:05');
$time->add(new DateInterval('PT' . $minutes_to_add . 'M'));
$stamp = $time->format('Y-m-d H:i');
The ISO 8601 standard for durationis a string in the form of P{y}Y{m1}M{d}DT{h}H{m2}M{s}Swhere the {*}parts are replaced by a number value indicating how long the duration is.
持续时间的ISO 8601 标准是一个字符串，P{y}Y{m1}M{d}DT{h}H{m2}M{s}S其中的{*}部分被一个数字值替换，该值指示持续时间的长度。
For example, P1Y2DT5Smeans 1 year, 2 days, and 5 seconds.
例如，P1Y2DT5S表示 1 年 2 天和 5 秒。
In the example above, we are providing PT5M(or 5 minutes) to the DateIntervalconstructor.
在上面的示例中，我们为构造函数提供PT5M（或 5 分钟）DateInterval。

PHP's DateTime classhas a useful modifymethod which takes in easy-to-understand text.
PHP 的 DateTime 类有一个有用的修改方法，它接收易于理解的文本。
$dateTime = new DateTime('2011-11-17 05:05');
$dateTime->modify('+5 minutes');
You could also use string interpolation or concatenation to parameterize it:
您还可以使用字符串插值或串联来参数化它：
$dateTime = new DateTime('2011-11-17 05:05');
$minutesToAdd = 5;
$dateTime->modify("+{$minutesToAdd} minutes");

You can do this with native functions easily:
您可以使用本机函数轻松做到这一点：
strtotime('+59 minutes', strtotime('2011-11-17 05:05'));
I'd recommend the DateTime class method though, just posted by Tim.
不过，我建议使用 DateTime 类方法，它刚刚由 Tim 发布。

I thought this would help some when dealing with time zones too. My modified solution is based off of @Tim Cooper's solution, the correct answer above.
我认为这在处理时区时也会有所帮助。我修改后的解决方案基于@Tim Cooper 的解决方案，即上面的正确答案。
$minutes_to_add = 10;
$time = new DateTime();
**$time->setTimezone(new DateTimeZone('America/Toronto'));**
$time->add(new DateInterval('PT' . $minutes_to_add . 'M'));
$timestamp = $time->format("Y/m/d G:i:s");
The bold line, line 3, is the addition. I hope this helps some folks as well.
粗线，第 3 行，是加法。我希望这也能帮助一些人。

A bit of a late answer, but the method I would use is:
有点晚的答案，但我会使用的方法是：
// Create a new \DateTime instance
$date = DateTime::createFromFormat('Y-m-d H:i:s', '2015-10-26 10:00:00');
// Modify the date
$date->modify('+5 minutes');
// Output
echo $date->format('Y-m-d H:i:s');
Or in PHP >= 5.4
或者在 PHP >= 5.4
echo (DateTime::createFromFormat('Y-m-d H:i:s', '2015-10-26 10:00:00'))->modify('+5 minutes')->format('Y-m-d H:i:s')
回答by Beaudinn Greve
If you want to give a variable that contains the minutes.
如果你想给出一个包含分钟的变量。
Then I think this is a great way to achieve this.
然后我认为这是实现这一目标的好方法。
$minutes = 10;
$maxAge = new DateTime('2011-11-17 05:05');
$maxAge->modify("+{$minutes} minutes");
回答by DeathRs
Use strtotime("+5 minute", $date);
用 strtotime("+5 minute", $date);
Example:例子：
$date = "2017-06-16 08:40:00";
$date = strtotime($date);
$date = strtotime("+5 minute", $date);
echo date('Y-m-d H:i:s', $date);

I don't know why the approach set as solution didn't work for me. So I'm posting here what worked for me in hope it can help anybody:
我不知道为什么设置为解决方案的方法对我不起作用。所以我在这里发布对我有用的东西，希望它可以帮助任何人：
$startTime = date("Y-m-d H:i:s");
//display the starting time
echo '> '.$startTime . "<br>";
//adding 2 minutes
$convertedTime = date('Y-m-d H:i:s', strtotime('+2 minutes', strtotime($startTime)));
//display the converted time
echo '> '.$convertedTime;
回答by Robert Schwindaman
As noted by Brad and Nemoden in their answers above, strtotime() is a great function. Personally, I found the standard DateTime Object to be overly complicated for many use cases. I just wanted to add 5 minutes to the current time, for example.
正如 Brad 和 Nemoden 在上面的回答中指出的那样， strtotime() 是一个很棒的函数。就个人而言，我发现标准 DateTime 对象对于许多用例来说过于复杂。例如，我只想为当前时间增加 5 分钟。
I wrote a function that returns a date as a string with some optional parameters:
1.) time:String | ex: "+5 minutes" (default = current time)
2.) format:String | ex: "Y-m-d H:i:s" (default = "Y-m-d H:i:s O")
我编写了一个函数，该函数将日期作为带有一些可选参数的字符串返回：
1.) time:String | 例如：“+5 分钟”（默认值 = 当前时间）
2.) 格式：字符串 | 例如：“Ymd H:i:s”（默认值 =“Ymd H:i:s O”）
Obviously, this is not a fully featured method. Just a quick and simple function for modifying/formatting the current date.
显然，这不是一个功能齐全的方法。只是一个用于修改/格式化当前日期的快速简单的功能。
function get_date($time=null, $format='Y-m-d H:i:s O')
{
if(empty($time))return date($format);
return date($format, strtotime($time));
}
// Example #1: Return current date in default format
$date = get_date();
// Example #2: Add 5 minutes to the current date
$date = get_date("+5 minutes");
// Example #3: Subtract 30 days from the current date & format as 'Y-m-d H:i:s'
$date = get_date("-30 days", "Y-m-d H:i:s");
