What is the best practice for converting a date to German format in PHP?

When converting a date to German format in PHP, the best practice is to use the `date()` function along with the `setlocale()` function to set the locale to German. This will ensure that the date is displayed in the correct format according to German standards.

setlocale(LC_TIME, 'de_DE');
$date = date('d.m.Y', strtotime($your_date_variable));
echo $date;
