[php] PHP strtotime +1 month adding an extra month

I have a simple variable that adds one month to today:

$endOfCycle = date("Y-m", strtotime("+1 month"));

Today is January 2013, so I would expect to get back 2013-02 but I'm getting 2013-03 instead. I can't figure out why it's jumping to March.

 $endOfCycle = date("Y-m", mktime(0, 0, 0, date("m", time())+1 , 15, date("m", time())));

Maybe because its 2013-01-29 so +1 month would be 2013-02-29 which doesn't exist so it would be 2013-03-01

You could try

date('m/d/y h:i a',(strtotime('next month',strtotime(date('m/01/y')))));

from the comments on http://php.net/manual/en/function.strtotime.php

today is 29th of January, +1 month means 29th of Fabruary, but because February consists of 28 days this year, it overlaps to the next day which is March 1st

instead try

strtotime('next month')

try this:

$endOfCycle = date("Y-m", time()+2592000);

this adds 30 days, not exactly a month tough.

You can use this code to get the next month:

$ts = mktime(0, 0, 0, date("n") + 1, 1);
echo date("Y-m-d H:i:s", $ts);
echo date("n", $ts);

Assuming today is 2013-01-31 01:23:45 the above will return:

2013-02-01 00:00:00
2

This should be

$endOfCycle=date('Y-m-d', strtotime("+30 days"));

strtotime

expects to be given a string containing a US English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.

while

date

Returns a string formatted according to the given format string using the given integer timestamp or the current time if no timestamp is given.
