What are some common issues with using the setlocale() function in PHP for language localization?

One common issue with using the setlocale() function in PHP for language localization is that it may not work as expected on different server environments due to differences in available locales or configurations. To solve this issue, you can use a fallback mechanism by checking if the desired locale is set and if not, fallback to a default locale. 

$locale = 'fr_FR'; // Desired locale
if (setlocale(LC_ALL, $locale) === false) {
    $locale = 'en_US'; // Fallback locale
    setlocale(LC_ALL, $locale);
}
