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.
In case this was a PHP problem, snapshots of the sources are packaged
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.

More to the point, "next" is specifically equated to "2" (or "+2") in
the documentation referenced by the strtotime() manual page, so your
expectation for "next month" is simply wrong.
However, "this" is also specifically equated to a "zero-valued
displacement ... preferred in date strings like `this thursday'" (which
doesn't sound very "fuzzy" to me), so the behaviour of "this month" in
your example is, at the least, questionable. On this basis, I'm
re-opening this bug (with a revised summary) so a developer who knows
their way round strtotime() can take another look.

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.
And this is expected behaviour. (this, next, etc. are FUZZY, rtfm)

Description:
------------
strtotime adds an extra month when using the phrase
"this month" or "next month". Using '+1 months' or '+0
months' works fine, though.
And, no, I'm not adding a month to 'Jan. 30'.
Reproduce code:
---------------
echo date('Y-m-d', strtotime('last month'));
echo date('Y-m-d', strtotime('this month'));
echo date('Y-m-d', strtotime('next month'));
echo date('Y-m-d', strtotime('-1 months'));
echo date('Y-m-d', strtotime('+0 months'));
echo date('Y-m-d', strtotime('+1 months'));
Expected result:
----------------
2003-11-09
2003-12-09
2004-01-09
2003-11-09
2003-12-09
2004-01-09
Actual result:
--------------
2003-11-09
2004-01-09
2004-02-09
2003-11-09
2003-12-09
2004-01-09
