<ul>
<?php
$event_date = get_sub_field('event_date'); // 20150203
$event_date_format = DateTime::createFromFormat('Ymd', $event_date);
setlocale(LC_ALL, 'de_DE');
?>
<li>
<h6><?php echo $event_date_format->format('d');?>. <?php echo $event_date_format->format('F');?></h6>
<p><?php echo $event_date_format->format('H');?>:<?php echo $event_date_format->format('i');?></p>
</li>
</ul>
The output of this is
03. February
19:25
Why does setlocale not have any impact on this. I want my Month "F" to be in german like 3. Feber 19:25
Any idea what I'm doing wrong here?
UPDATE 1:
If I try using strftime()
i suddenly get a different date output. it is in german but wrong?
<ul>
<?php
$event_date = get_sub_field('event_date');
$event_date_format = DateTime::createFromFormat('Ymd', $event_date);
setlocale(LC_ALL, 'de_DE');
?>
<li>
<h6><?php echo $event_date_format->format('d');?>. <?php echo strftime('%B', $event_date);?></h6>
<p><?php echo $event_date_format->format('H');?>:<?php echo $event_date_format->format('i');?></p>
</li>
</ul>
Suddenly the output date is not 03. February
but 03. August
, even though the date should be February.
Any ideas?
UPDATE 2:
This is pretty weird. I just checked the variable $event_date
online in a unix conversion tool and the I get this …
$event_date: 20150203
Sat, 22 Aug 1970 05:16:43 GMT
The value is set inside a wordpress backend with a datepicker and clearly says 03/02/2015
回答1:
date()
and DateTime do not respect locale
use strftime()
http://php.net/manual/en/function.strftime.php

To format dates in other languages, you should use the setlocale() and strftime() functions instead of date().

Annoyingly, date
is not locale-aware. From the manual:
To format dates in other languages, you should use the setlocale() and strftime() functions instead of date.
You probably want:
setlocale(LC_TIME, 'de_DE');
echo strftime('%B');
Alternatively, checkout Carbon. It's got a consistent API that includes locale-awareness. As an example:
setlocale(LC_TIME, 'German');
echo Carbon::now()->formatLocalized('%B'); // Sonntag
