How can the issue of changing locale settings in a multi-threaded environment like IIS be effectively managed when using PHP for internationalization?

In a multi-threaded environment like IIS, changing locale settings for internationalization in PHP can cause conflicts between threads. To effectively manage this issue, it is recommended to set the locale settings within each thread independently to avoid interference. This can be achieved by using the setlocale function within the PHP script to set the desired locale for each thread.

// Set locale settings for each thread independently
setlocale(LC_ALL, 'en_US.UTF-8');
