Keloran, your bug report is confusing with respect to day/month order. I am
assuming you mean m/d when you say 02/01 and 03/01 but your script says d/m/Y.
Please provide an actual script with a timestamp baked in. Like this:
echo date("d/m/Y H:i:s\n",1328126500);
echo date("d/m/Y\n", strtotime("yesterday last year",1328126500));
That outputs:
01/02/2012 12:01:40
31/01/2011
which looks completely correct to me.
Austin, yours is not a bug. When you add a month to Jan.30 it goes to Feb.30
which doesn't exist. So it adjusts it to Mar.1. strtotime follows the standard
UNIX date addition behaviour in this. From your Linux command line try this:
% date
Mon Jan 30 17:49:22 EST 2012
% date --date='+1 month' +'Next month is %B'
Next month is March
You can find this behaviour documented here:

strings.html#SEC125

To add to this...
date('n', strtotime('+ 1 month', time()));
That should be 2 and it is returning a 3. Now it is 3:30 PM EST when i noticed
this, so by using a preset timestamp you can reproduce this.
date('n', strtotime('+ 1 month', '1327954976'));
Will return 3 instead of 2 as well.
I am guessing this will never be fixed, and if not, maybe say "hey, we cant fix
this one" -OR "this is more work to fix than it is worth" instead of ignoring
the problem?
https://bugs.php.net/bug.php?id=27793 that is from 2004!!!
Not to mention there is a note at the bottom of it that it was posted at least
5
other times.

Description:
------------
If you do the test, you should get if today is
02/01/2012
the result should be
03/01/2011
but instead you get
02/01/2011
Test script:
---------------
echo date("d/m/Y", strtotime("yesterday last year"));
Expected result:
----------------
03/01/2011
Actual result:
--------------
02/01/2011
