Add 60 days to date

[kproctor]

Hi, 

 

I have been looking all day for code to add $x to $date.I have been able to find examples to get me part way. But I am not able to get the answer I need. 

 

 

Here is a snipped of code I've been working with. 

 

<?php

 

echo "<br>";

 

//function remainingTerm($trmStartDate, $LNTerm){

 

date_default_timezone_set('America/New_York');

 

// date format yyyy-mm-dd

//http://stackoverflow.com/questions/10448119/how-to-calculate-the-difference-of-datetime-field-and-now-in-php

$LNTerm = 60;

$trmStartDate = 2016-09-01;

 

$startDate=date_create($trmStartDate);

 

$matDate = strtotime('"+'.$LNTerm. 'months"', strtotime($trmStartDate));

 

//$matDate = date_create($matDate);

 

//$maturityDate=date_create("2022-12-12");

$diff=date_diff($startDate,$matDate);

//echo $diff->format('%R%a days');

 

echo "<br>";

 

echo $matDate->format('Y-m-d');

 

 

//return $daysToMaturity;

//}

?>

Hi, thank you for the reply. how do I change the number of days to a variable. I've tried this. 

 

$date->add(new DateInterval("'P".$LNTerm."M'"));

To help clariy I am trying to add X days to some days in the past. (this date will be greater than today). I want to take this date and subtract it from today to determine how many days until that date.

$LNTerm = 60;

$LNUnit = 'D';


$dt = new DateTime('2017-02-01');

$di = new DateInterval("P$LNTerm$LNUnit");

$dt->add($di);

echo $dt->format('Y-m-d');                            //--> 2017-04-02

$days_until = $dt->diff(new DateTime())->days;

echo "<br>$days_until";                               //--> 19
