I18N::Collate - phpMan

NAME
    I18N::Collate - compare 8-bit scalar data according to the current
    locale

SYNOPSIS
        use I18N::Collate;
        setlocale(LC_COLLATE, 'locale-of-your-choice');
        $s1 = I18N::Collate->new("scalar_data_1");
        $s2 = I18N::Collate->new("scalar_data_2");

DESCRIPTION
      ***

      WARNING: starting from the Perl version 5.003_06
      the I18N::Collate interface for comparing 8-bit scalar data
      according to the current locale

            HAS BEEN DEPRECATED

      That is, please do not use it anymore for any new applications
      and please migrate the old applications away from it because its
      functionality was integrated into the Perl core language in the
      release 5.003_06.

      See the perllocale manual page for further information.

      ***

    This module provides you with objects that will collate according to
    your national character set, provided that the POSIX setlocale()
    function is supported on your system.

    You can compare $s1 and $s2 above with

        $s1 le $s2

    to extract the data itself, you'll need a dereference: $$s1

    This module uses POSIX::setlocale(). The basic collation conversion is
    done by strxfrm() which terminates at NUL characters being a decent C
    routine. collate_xfrm() handles embedded NUL characters gracefully.

    The available locales depend on your operating system; try whether
    "locale -a" shows them or man pages for "locale" or "nlsinfo" or the
    direct approach "ls /usr/lib/nls/loc" or "ls /usr/lib/nls" or "ls
    /usr/lib/locale". Not all the locales that your vendor supports are
    necessarily installed: please consult your operating system's
    documentation and possibly your local system administration. The locale
    names are probably something like "xx_XX.(ISO)?8859-N" or
    "xx_XX.(ISO)?8859N", for example "fr_CH.ISO8859-1" is the Swiss (CH)
    variant of French (fr), ISO Latin (8859) 1 (-1) which is the Western
    European character set.
