The Locale class

INTRODUCTION

	A  "Locale"  is  an  identifier  used to get language, culture, or regionally-specific behavior from an API. PHP locales are organized and
       identified the same way that the CLDR locales used by ICU (and many vendors of Unix-like operating systems, the Mac, Java,  and	so  forth)
       use. Locales are identified using RFC 4646 language tags (which use hyphen, not underscore) in addition to the more traditional underscore-
       using identifiers. Unless otherwise noted the functions in this class are tolerant of both formats.

	Examples of identifiers include:

	      oen-US (English, United States)

	      ozh-Hant-TW (Chinese, Traditional Script, Taiwan)

	      ofr-CA, fr-FR (French for Canada and France respectively)

	The Locale class (and related procedural functions) are used to interact with locale identifiers--to verify that  an  ID  is  well-formed,
       valid, etc. The extensions used by CLDR in UAX #35 (and inherited by ICU) are valid and used wherever they would be in ICU normally.

	Locales cannot be instantiated as objects. All of the functions/methods provided are static.

	The  null  or  empty  string  obtains the "root" locale. The "root" locale is equivalent to "en_US_POSIX" in CLDR. Language tags (and thus
       locale identifiers) are case insensitive. There exists a canonicalization function to make case match the specification.

       o publicstatic string Locale::getDisplayName (string  $locale, [string  $in_locale])

       o publicstatic string Locale::getDisplayRegion (string  $locale, [string  $in_locale])

       o publicstatic string Locale::getDisplayScript (string  $locale, [string  $in_locale])

       o publicstatic string Locale::getDisplayVariant (string	$locale, [string  $in_locale])

       o publicstatic string Locale::getScript (string	$locale)

       o publicstatic string Locale::lookup (array  $langtag, string  $locale, [bool  $canonicalize = false], [string  $default])

       o publicstatic array Locale::parseLocale (string  $locale)

       o publicstatic bool Locale::setDefault (string  $locale)

PREDEFINED CONSTANTS

	      o Locale::DEFAULT_LOCALE ( null) - Used as locale parameter with the methods of the various locale affected classes, such as Number-
		Formatter. This constant would make the methods to use default locale.

	These constants describe the choice of the locale for getLocalte method of different classes.

	      o Locale::ACTUAL_LOCALE ( string) -This is locale the data actually comes from.

	      o Locale::VALID_LOCALE ( string) -This is the most specific locale supported by ICU.

	These  constants define how the Locales are parsed or composed. They should be used as keys in the argument array to locale_compose(3) and
       are returned from locale_parse(3) as keys of the returned associative array.

	      o Locale::LANG_TAG ( string) -Language subtag

	      o Locale::EXTLANG_TAG ( string) -Extended language subtag

	      o Locale::SCRIPT_TAG ( string) -Script subtag

	      o Locale::REGION_TAG ( string) -Region subtag

	      o Locale::VARIANT_TAG ( string) -Variant subtag

	      o Locale::GRANDFATHERED_LANG_TAG ( string) -Grandfathered Language subtag

	      o Locale::PRIVATE_TAG ( string) -Private subtag
