What are the potential pitfalls of manually converting dates to German in PHP?

When manually converting dates to German in PHP, a potential pitfall is not accounting for different date formats and language conventions. To avoid errors and inconsistencies, it is recommended to use PHP's built-in date formatting functions with the appropriate locale settings.

// Set the locale to German
setlocale(LC_TIME, 'de_DE');

// Convert a date to German format
$date = '2022-01-15';
$germanDate = strftime('%d. %B %Y', strtotime($date));

echo $germanDate; // Output: 15. Januar 2022
