How to add time with another time in php?

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.

The date time format I have is:

2011-11-17 05:05: year-month-day hour:minute

Minutes to add will just be a number between 0 and 59

I would like the output to be the same as the input format with the minutes added.

Could someone give me a working code example, as my attempts don't seem to be getting me anywhere?

$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 duration is a string in the form of P{y}Y{m1}M{d}DT{h}H{m2}M{s}S where the {*} parts are replaced by a number value indicating how long the duration is.

For example, P1Y2DT5S means 1 year, 2 days, and 5 seconds.

In the example above, we are providing PT5M [or 5 minutes] to the DateInterval constructor.

PHP's DateTime class has a useful modify method which takes in easy-to-understand text.

$dateTime = new DateTime['2011-11-17 05:05'];
$dateTime->modify['+5 minutes'];

You could also use string interpolation or concatenation to parameterize it:

$dateTime = new DateTime['2011-11-17 05:05'];
$minutesToAdd = 5;
$dateTime->modify["+{$minutesToAdd} minutes"];

$newtimestamp = strtotime['2011-11-17 05:05 + 16 minute'];
echo date['Y-m-d H:i:s', $newtimestamp];

result is

2011-11-17 05:21:00

Live demo is here

If you are no familiar with strtotime yet, you better head to php.net to discover it's great power :-]

You can do this with native functions easily:

strtotime['+59 minutes', strtotime['2011-11-17 05:05']];

I'd recommend the DateTime class method though, just posted by Tim.

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:

$startTime = date["Y-m-d H:i:s"];

//display the starting time
echo '> '.$startTime . "
";

//adding 2 minutes
$convertedTime = date['Y-m-d H:i:s', strtotime['+2 minutes', strtotime[$startTime]]];

//display the converted time
echo '> '.$convertedTime;

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.

$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.

A bit of a late answer, but the method I would use is:

// 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

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']

If you want to give a variable that contains the minutes.

Then I think this is a great way to achieve this.

$minutes = 10;
$maxAge = new DateTime['2011-11-17 05:05'];
$maxAge->modify["+{$minutes} minutes"];

Use strtotime["+5 minute", $date];

Example:

$date = "2017-06-16 08:40:00";
$date = strtotime[$date];
$date = strtotime["+5 minute", $date];
echo date['Y-m-d H:i:s', $date];

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.

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"]

Obviously, this is not a fully featured method. Just a quick and simple function for modifying/formatting the current date.

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"];

One more example of a function to do this: [changing the time and interval formats however you like them according to this for function.date, and this for DateInterval]:

[I've also written an alternate form of the below function.]

// Return adjusted time.

function addMinutesToTime[ $dateTime, $plusMinutes ] {

    $dateTime = DateTime::createFromFormat[ 'Y-m-d H:i', $dateTime ];
    $dateTime->add[ new DateInterval[ 'PT' . [ [integer] $plusMinutes ] . 'M' ] ];
    $newTime = $dateTime->format[ 'Y-m-d H:i' ];

    return $newTime;
}

$adjustedTime = addMinutesToTime[ '2011-11-17 05:05', 59 ];

echo '
Adjusted Time: ' . $adjustedTime . '
' . PHP_EOL . PHP_EOL;

one line mysql datetime format

$mysql_date_time = [new DateTime[]]->modify['+15 minutes']->format["Y-m-d H:i:s"];

Without using a variable:

 $yourDate->modify["15 minutes"];
 echo $yourDate->format[ "Y-m-d H:i"];

With using a variable:

 $interval= 15;
 $yourDate->modify["+{$interval } minutes"];  
 echo $yourDate->format[ "Y-m-d H:i"];
