# nl_langinfo

(PHP 4 >= 4.1.0, PHP 5)

nl_langinfo -- Query language and locale information

## Description

string nl_langinfo ( int item )

nl_langinfo() is used to access individual elements of the locale categories. Unlike localeconv(), which returns all of the elements, nl_langinfo() allows you to select any specific element.

If `item` is not valid, `FALSE` will be returned.

`item` may be an integer value of the element or the constant name of the element. The following is a list of constant names for `item` that may be used and their description. Some of these constants may not be defined or hold no value for certain locales.
