What are the potential pitfalls of using setlocale() function in PHP for date localization?

Potential pitfalls of using setlocale() function in PHP for date localization include compatibility issues across different operating systems and versions of PHP, as well as the risk of inadvertently affecting other parts of the application's functionality due to the global nature of setlocale(). To mitigate these risks, it is recommended to use the IntlDateFormatter class in PHP, which provides a more reliable and consistent way to format dates based on locale settings. 

// Using IntlDateFormatter class for date localization
$formatter = new IntlDateFormatter('en_US', IntlDateFormatter::MEDIUM, IntlDateFormatter::NONE);
$date = new DateTime();
echo $formatter->format($date);
