Wrong output on strftime() and mktime()

Question

Thas my little function:

setlocale(LC_TIME, 'de_DE');
$date_array = array($blog_month,$blog_year);
var_dump($date_array); 
$title_date = strftime("%B %Y", mktime(0,0,0, $date_array[0], 0, $date_array[1]));
echo $title_date;

the var_dump gives

array(2) {
  [0]=> int(5)
  [1]=> int(2013)
}

So the array is correct. But the $title_date is always wrong. In this particular case the echo shows April 2013. I guess something is wrong with the mktime, because i checked the timestamp it gives and it is always the wrong one.

I did read the PHP documentation, and this should be work, don't know whats wrong. Any idea or suggestion?

Answer 1

The setlocale function returns false if the locale couldn't be set, and you are ignoring the return value. In this case the call must be failing (possibly because the de_DE locale isn't installed?) and strftime still formats dates in English.

On the other hand, the day 0 corresponds to the "last day of the month before". So mktime is returning April 30, not May 1 if that's what you expect. For May 1 use this:

mktime(0,0,0, $date_array[0], 1, $date_array[1])
