New Comment:
To the people adding comments about +-1 month here. This really isn't a
bug. Read the link Derick provided:
http://derickrethans.nl/obtaining-the-next-month-in-php.html
It doesn't matter if you are going ahead 1 month or back 1 month. The
logic is the same. It tries to find Feb.30 which doesn't exist, so
instead of walking backwards to Feb.28 it assumes you meant 2 days after
Feb.28 which is obviously in March. Like I said in the comments at that
link, for better or worse, this is the UNIX convention for time
manipulation. Most UNIX tools will behave exactly like this. In order to
do this correctly, you should be specifying a day in the month as Derick
suggests in that post.

I am having the exact same error as fortizma.
<?php
$runtm = time();
$month = strtotime( '-1 month', $runtm );
$ts = date( 'n/j/Y g:i a', $runtm );
$ts2 = date( 'n/j/Y g:i a', $month );
$last = date( 'Y-m-F', $month );
echo $ts . PHP_EOL . $ts2 . PHP_EOL . $last . PHP_EOL . PHP_EOL;

Derik, thanks for your reply, but in my last reply, I'm talking about
last month,
no next month.
Thanks in advance.

Based on the current date which is march 30, 2011.
if I try echo date('Y-m-d', strtotime('-1 months')); I would expect
2011-02-28,
but what I'm getting is 2011-03-02.
Do this occur due to 2011 is not a leap year?

This bug has been fixed in CVS.

every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.
