$currmonth = date("m");
for ($i = 1; $i <= 11; $i++) {
$m[$i] = date("m/d/y"), mktime(0,0,0,$currmonth-$i, 1, 2009));
}
Something like that. mktime() is remarkably flexible. If you start on
month 3 and you subtract 5, you get month = -2. So that would be
-2/1/2009, which mktime will translate to 11/1/2008.
This is totally off the top of my head, but you get the idea. Works with
days and years too. Sometimes it's useful when going backwards and not
sure how many days the previous month had (without doing another call to
find out).
