What are the advantages of using IntlDateFormatter in PHP for date localization compared to setlocale()?

When it comes to date localization in PHP, using IntlDateFormatter is preferred over setlocale() for several reasons. IntlDateFormatter provides more flexibility and control over date formatting, supports a wider range of locales, and is not affected by global settings that may impact other parts of the application. Additionally, IntlDateFormatter is part of the Internationalization extension (intl), which is more modern and robust compared to the older setlocale() function. 

// Using IntlDateFormatter for date localization
$locale = 'fr_FR'; // French locale
$date = new DateTime('2022-01-15');
$formatter = new IntlDateFormatter($locale, IntlDateFormatter::MEDIUM, IntlDateFormatter::NONE);
echo $formatter->format($date);
