What are common pitfalls when setting up gettext for multilingual websites in PHP?

One common pitfall when setting up gettext for multilingual websites in PHP is not properly setting the locale. Make sure to set the correct locale before calling gettext functions to ensure the correct language translations are loaded.

// Set the locale
$locale = 'fr_FR'; // French locale
setlocale(LC_ALL, $locale);

// Specify the location of translation files
bindtextdomain('messages', 'path/to/translations');

// Choose domain
textdomain('messages');
