Since this is reported as a bug so often, it might make sense to update the
documentation to warn developers about this unexpected/unintuitive behavior.
Regardless of whether you think it's a bug or not, it's clearly something that
many developers stumble over, so it should be prominently documented.

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.
Already reported atleast *5* times.

Description:
------------
strtotime("- x month") will not work properly when
around a month change. The following code example was
run on 31.march. I have seen the previous bug reports
that indicate that month is really an alias for 30.5
days. However, this causes problems when you need to
correctly iterate (dynamically) with the month keyword.
It should iterate correctly when its specified as month,
if not my opinion is that implementations should use
strtotime("- ".$num*"30.5"." days");
Reproduce code:
---------------
for( $c=0;$c<12;$c++ )
echo date("F",strtotime("-".$c." month"))."<br>";
Expected result:
----------------
March
February
Januar
December
November
October
Actual result:
--------------
March
January
December
December
October
October
