nl_langinfo — Query language and locale information

说明

nl_langinfo ( int $item ) : string|false

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 you are looking for the stand-alone (nominative form) of a month, you may not be able to use nl_langinfo(), but with PHP 5.5 you can use something like:

<?php
echo IntlDateFormatter::formatObject(
         new DateTime('2013-01-01 00:00:00 Europe/Moscow'),
         'LLLL',
         'ru_RU');
?>

Note that the format uses the ICU patterns, not the PHP date() patterns.

The value MON_(1-12) has special behavior in Russian locale: it returns declinated month names, that can be used as part of a date string, but not on their own.

For instance instead of "Январь" (the proper nominative form) it returns "Января" (form declinated for use in dates).

There seems to be no way to get the nominative form of the month name - one has to use translations instead.
