Waarschuwing: > The locale information is maintained per process, not per thread. If you are running PHP on a multithreaded server API , you may experience sudden changes in locale settings while a script is running, though the script itself never called . This happens due to other scripts running in different threads of the same process at the same time, changing the process-wide locale using . On Windows, locale information is maintained per thread as of PHP 7.0.5. setlocale``setlocale
