PHP - Sum time to current time, best practice

Question

Hi i'm trying to sum time with the current date time, this code seems to work:

$now = time();
$_day = strtotime('+1day',$now);
$_week = strtotime('+7day',$now);
$_month = strtotime('+1month',$now);
$_year = strtotime('+1year',$now);

what i'm wondering is if is there any other way , maybe better way of doing this .. can anyone show me new ways and the reasons why i should turn to another syntax? I would like to do this more accurate as possible, so if i can reflect this script it is great!

thanks

EDIT:

just to be clear i need to use unix timestamps i don't need formatted dates/datetimes

Well, there are `DateTime::add` and `DateInterval` >= PHP 5.3.0 — irrelephant, Dec 25 '12 at 12:11

If PHP version you use allows (PHP 5 >= 5.3.0) you to use DateTime and DateInterval classes, you coud use them.

example:

$dateTime=new DateTime();
$plusDay=new DateInterval('P1D');
var_dump($dateTime->add($plusDay));

$dateTime=new DateTime();
$plusWeek=new DateInterval('P1W');
var_dump($dateTime->add($plusWeek));

$dateTime=new DateTime();
$plusMonth=new DateInterval('P1M');
var_dump($dateTime->add($plusMonth));

I hope this is helpful.

If you are running `(PHP 5 >= 5.3.0)` – Chris Dec 25 '12 at 12:22
yes, correct. I didn't mentioned this explicitly in the post.. But `if php version allows..` hints that datetime and dateinterval classes aren't available in old php-versions :) – Ruslan Polutsygan Dec 25 '12 at 12:27
It wasn't meant as an insult. Tried the code out of curiosity and realised in the process that my Xampp version needs updating. Cheers :) – Chris Dec 25 '12 at 12:31
Do not worry. I was not injured :) Cheers – Ruslan Polutsygan Dec 25 '12 at 12:48
@RuslanPolutsygan sorry to be sure, what's the sintax for +1year? – itsme Dec 25 '12 at 19:55

@Badaboooooom 1 year interval - `$plusYear=new DateInterval('P1Y');` check syntax of string passed into constructor http://php.net/manual/en/dateinterval.construct.php – Ruslan Polutsygan Dec 26 '12 at 14:10

I believe that strtotime() is as simple as you're going to get in PHP. All 3 of the answers to this SO question chose to use that syntax, and all of the various tutorials I see around the web use it. strtotime() makes thinking about date arithmetic a lot easier than other approaches.

Try this solution:

date("Y-m-d", strtotime("+1 day"));
date("Y-m-d", strtotime("+7 days"));
date("Y-m-d", strtotime("+1 month"));
date("Y-m-d", strtotime("+1 year"));
