What potential issues can arise when trying to format dates in PHP for different languages or regions?

When formatting dates in PHP for different languages or regions, the main issue that can arise is the inconsistency in date formats and translations. To solve this problem, you can use the setlocale() function in PHP to set the desired locale before formatting the date.

// Set the locale to the desired language or region
setlocale(LC_TIME, 'fr_FR');

// Format the date using the strftime function
$date = strftime('%A %d %B %Y', strtotime('2022-01-01'));

echo $date;
