strtotime is not working proper in php for future date?

Question

When i am converting date from dmY in Ymd format. i am facing some issues for it.

example 19/08/1989 will convert into 1989/08/19 (it's correct),

19/08/2059 will convert into 1970/01/01 (it's not correct)

$re_date = date('Y-m-d', strtotime($_POST['re_date']));

Help me please. thanks in advance.

Answer 1

The maximum date allowed is Tue, 19 Jan 2038 03:14:07 UTC on 32 bit system

From the strotime docs :

Note:

The valid range of a timestamp is typically from Fri, 13 Dec 1901 20:45:54 UTC to Tue, 19 Jan 2038 03:14:07 UTC.

If you want it to work for 32 bit system then try like this using DateTime :

$date = new DateTime($_POST['re_date']);

echo $date->format('Y-m-d');

Answer 2

better trick

$str=explode('/',$_POST['re_date']);

$newdate = $str[2].'/'.$str[1].'/'.$str[0];

Answer 3

$ re_date = date（'Y / m / d'，strtotime（$ _ POST ['re_date']））;;

Answer 4

$date = $_POST['re_date'];
$date = str_replace("/", "-", $date);
$re_date = date('Y-m-d', strtotime($date));
