PHP Strtotime -1month -2month

Question

Hi,

This was working fine yesterday with no changes to the code.

echo date("M", strtotime("-3 month", time()) );
echo date("M", strtotime("-2 month", time()) );
echo date("M", strtotime("-1 month", time()) );
echo date("M", time());

The output it was producing yesterday was as you would expect- i.e. Apr, May, Jun, Jul

Today it echoes May May Jul Jul

Any ideas?

Thanks in advance.

Answer 1

Hi,

It might be related to bug #44073

You could try with something like this :

echo date("M", strtotime("-3 month", strtotime(date("F") . "1")) ) . "\n";
echo date("M", strtotime("-2 month", strtotime(date("F") . "1")) ) . "\n";
echo date("M", strtotime("-1 month", strtotime(date("F") . "1")) ) . "\n";
echo date("M", time()) . "\n";

(Solution found in the comments section of strtotime ; direct link)

And the output :

Apr
May
Jun
Jul

Kind of "cheating" with the date format and month's name and all that...

Answer 2

Try this instead of strtotime:

mktime(0, (date("n") - 3 + 12) % 12, 1)

The idea is to take the current month number (date("n")), substract the number of months from it you want (here -3), add 12 to it and then get modulo 12.
