Add years to todays date in php

I'm getting a weird date ('01/01/1970 00:00:00) when I run the following code in php:

$now = date('d/m/Y H:i:s', time());
$exp = date('d/m/Y H:i:s', strtotime($now .'+100 years'));

You're apparently falling into one or both the following problems:

  1. a simple formatting issue (this is wrong for sure) where, since you're using / as separator, strtotime interprets days as months and vice-versa; as you can read in the documentation page for strtotime (Notes paragraph):

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed

This can be easily fixed by changing your first line from:

$now = date('d\m\Y H:i:s', time());

to:

$now = date('d-m-Y H:i:s', time());
  1. the Year 2038 Problem. You can read about this too, in the same documentation page (same paragraph, right above the previous quote):

The valid range of a timestamp is typically from Fri, 13 Dec 1901 20:45:54 UTC to Tue, 19 Jan 2038 03:14:07 UTC. (These are the dates that correspond to the minimum and maximum values for a 32-bit signed integer)

If that's your case, you better use DateTime objects (as others suggested here), which do not suffer this limitation. Here's a line which should work:

$exp = date_format(date_create("+100 years"), 'd/m/Y H:i:s');

What is happening in your code is that:

  • since you're passing a non-existing date (and maybe because of a 32-bit environment too), strtotime returns false
  • when passing false to the second argument of the date function, which expects an int, false is cast to 0, which makes date return the Epoch Time.

It because you're giving the wrong date format for this function strtotime($now .'+100 years') and it returns false.

try that:

echo date('d/m/Y H:i:s', strtotime("+100 year"));

Try following one.

$now = date('d/m/Y H:i:s', strtotime('+100 years'));

Output => 26/06/2117 18:58:07

$year = date('Y-m-d H:i:s', strtotime('+5 years'));
echo $year;
?>

I would try something like this

$date = new DateTime();
$exp = $date->modify('+100 years')->format('d/m/Y H:i:s');
