Question

I’ve some data which formatted like: 04.09.1953

I want to convert this format to: 1953-09-04

Is there any way or php function to do this?

Answer 1

just use strtotime() to get a timestamp and then date() to convert that timestamp to the format you need:

$timestamp = strtotime("04.09.1953");
echo date("Y-m-d", $timestamp);

EDIT:
If you’re having some “exotic” format as input, you might need to use explode(), list() and mktime() to build the timestamp on your own:

list($y,$m,$d) = explode(".","04.09.1953");
$timestamp = mktime(0,0,0,$m,$d,$y);
echo date("Y-m-d", $timestamp);
