I have some short dates in my POST variables.

If I do this:

$i = 0;
foreach ($data->week as $week) {
    $date = $_POST['date'.($i+1)];
    echo $date;
    ...
    $i++;
 }

it returns the correct short dates e.g. 09.12. and 12.12.

If I do this

echo date('d.m.Y', strtotime($date));

it's returning 09.12.2013 (correct) and 09.12.2013 (incorrect, should be 12.12.2013).

Andy ideas?

Answer 1

Your usage for strtotime isn't correct. With such call it will apply time value for current date. It's like:

var_dump(date('d.m.Y H:i:s', strtotime('12.12')));//09.12.2013 12:12:00
var_dump(date('d.m.Y H:i:s', strtotime('11.12')));//09.12.2013 11:12:00

Instead you should use DateTime API with it's createFromFormat() method.

Answer 2

Is something stopping you from using the DateTime class ? ;)

Do something like this

<?php
$dt = '12.12';
$ctime = DateTime::createFromFormat('d.m', $dt);
echo $ndate= $ctime->format('d.m.Y'); // "prints" 12.12.2013
