(PHP 3, PHP 4 )

setlocale -- Set locale information


string setlocale ( mixed category, string locale [, string ...])

string setlocale ( mixed category, array locale)

Category is a named constant (or string) specifying the category of the functions affected by the locale setting:

If locale is the empty string "", the locale names will be set from the values of environment variables with the same names as the above categories, or from "LANG".

If locale is zero or "0", the locale setting is not affected, only the current setting is returned.

If locale is an array or followed by additional parameters then each array element or parameter is tried to be set as new locale until success. This is usefull if a locale is known under different names on different systems or for providing a fallback for a possibly not available locale.

Замечание: Passing multiple locales is not available before PHP 4.3.0

Setlocale returns the new current locale, or FALSE if the locale functionality is not implemented in the platform, the specified locale does not exist or the category name is invalid. An invalid category name also causes a warning message.

Замечание: The return value of setlocale() depends on the system that PHP is running. It returns exactly what the system setlocale function returns.
