Question

I have this date format d-m-y on a string so that 01-01-12 is January, 1st of the year 2012.

Now, I want to convert this to a date object in php, to sort a set of dates, which are stored as string in an array.

Currently, I’m using strtotime and date

$keypoints[] = date('d-m-y', strtotime($date_str));

But this is sorting the resulting dates as if the format is y-m-d. The question is, how can I set the input format of the strtotime function?

Thanks in advance

Answer 1

Try this to get the date in Y-m-d format

$date_arr = explode('-', $date_str);
$keypoints[] = date("Y-m-d", mktime(0, 0, 0, $date_arr[1], $date_arr[0], $date_arr[2]));
