I am using $currenttime = time(); to get the time.

How to I subtract one month, 2 months, 3 months, etc. from the current time?

Thanks,

Also you could just make variables from using the date() command and then just use - to subtract the month part and echo the total

www.php.net/date

Wow, this is really complicated. Is there a simply way to subtract a month from time()?

Ok i made something simple for you, not sure what your using it for but what you described this might work

you can look at www.php.net/date to change the format of the month day and year. here it is in action
http://www.worcesterwideweb.com/work/months.php

PHP Code:

<?php
//the number of months to subtract
$subtractmonths = '3';
$fulldate = date("m.d.y");
$currentyear =  date("y");
$currentmonth = date("m");
$currentday =  date("d");

$subtract = date("m")-$subtractmonths;
echo "today's date is $fulldate<br>";
echo "$subtractmonths months(s) ago it was $subtract.$currentday.$currentyear";

?>

This one doesn't work when the month is near the end of the year. This version adds 3 months. Here is the result, with the code below:

today's date is 12.28.05
3 months(s) from now it will be 15.28.05

<?php
//the number of months to subtract
$addmonths = '3';
$fulldate = date("m.d.y");
$currentyear = date("y");
$currentmonth = date("m");
$currentday = date("d");

$add = date("m")+$addmonths;
echo "today's date is $fulldate<br>";
echo "$addmonths months(s) from now it will be $add.$currentday.$currentyear";

?>

FYI - I think I found something simple. This code will add one month to the current date, and it does adjust correctly:

$date_next_month = date ("m-d-Y", mktime (0,0,0,date("m")+1,date("d"),date("Y")));

Yeah, i made a slight mistake. this is what you should use. that way you can control it with a variable


http://www.worcesterwideweb.com/work/months.php

PHP Code:

<?php
// how many months to subtract
$monthssubtract = "13";
//get timestamp for past/future date I want
$pf_time = strtotime("-$monthssubtract months");
//format the date using the timestamp generated
$actual_date = date("F j, Y");
$pf_date = date("F j, Y", $pf_time);
echo "Today is $actual_date<br>";
echo "$monthssubtract months ago it was $pf_date";

?>

nice solution capetek,

I thought it was something like
date()-(60*60* 60 *24*31)
being that we are going by seconds, 60*60 is 1 minute, *60 is 1hr, *24 is one day, *31 is one month
