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.

Returns the new current locale, or false if the locale functionality is not implemented on your platform, the specified locale does not exist or the category name is invalid.
An invalid category name also causes a warning message. Category/locale names can be found in and . Different systems have different naming schemes for locales. RFC 1766ISO 639
