What are the advantages of using the IntlDateFormatter class over traditional date formatting methods in PHP?

When formatting dates in PHP, using the IntlDateFormatter class provides several advantages over traditional date formatting methods. This class allows for more flexibility in formatting options, supports a wider range of locales, handles different calendar systems, and provides better support for internationalization.

$date = new DateTime('2022-01-15');
$formatter = new IntlDateFormatter('en_US', IntlDateFormatter::MEDIUM, IntlDateFormatter::NONE);
echo $formatter->format($date);
