What are the best practices for handling locale settings in PHP when using functions like setlocale()?

When handling locale settings in PHP using functions like setlocale(), it is important to ensure that the desired locale is available on the server. It is also recommended to set the LC_ALL category to the desired locale to ensure consistency across all locale-sensitive functions. Additionally, it is good practice to restore the original locale settings after using setlocale() to prevent unintended side effects. 

// Check if the desired locale is available
if (setlocale(LC_ALL, 'en_US.UTF-8') === false) {
    echo 'Locale not available on this server';
    exit;
}

// Set the LC_ALL category to the desired locale
setlocale(LC_ALL, 'en_US.UTF-8');

// Your code here

// Restore the original locale settings
setlocale(LC_ALL, '0');
