+# BCP 47
+
+**PHP helpers to validate and normalize [IETF BCP 47 language tag](https://en.wikipedia.org/wiki/IETF_language_tag).**~~

+
+---
+
+
+## Utility functions
+
+```php
+$isValid = Toobo\Bcp47::isValidTag('i-klingon');  // true
+$isValid = Toobo\Bcp47::isValidTag('xy');         // false
+
+$filtered = Toobo\Bcp47::filterTag('EN-us');      // "en-US"
+$filtered = Toobo\Bcp47::filterTag('fr-latn-fx'); // "fr-FR"
+
+$isRTL = Toobo\Bcp47::isRtl('he');                // true
+$isRTL = Toobo\Bcp47::isRtl('en-us');             // false
+
+var_export(Toobo\Bcp47::splitTag('En-ca-Newfound'));
+array (
+  'language' => 'en',
+  'extLang' => '',
+  'script' => '',
+  'region' => 'CA',
+  'variant' => 'newfound',
+  'extension' => '',
+  'privateUse' => '',
+)
+```
+
+
+
+## The `Bcp47Tag` class
+
+The `Toobo\Bcp47Tag` offers an API similar to the utility functions, but it ensure it encapsulate
+a valid tag, in fact it throws when instantiated with an invalid tag.
+
+The class is `Stringable` and `JsonSerializable`, and it also implements the `Bcp47Code` interface
+defined by the [**`wikimedia/bcp-47-code`**](https://packagist.org/packages/wikimedia/bcp-47-code)
+package.
+
+```php
+$tag = Toobo\Bcp47Tag::new('En-ca-Newfound');
+
+assert($tag->isSameCodeAs(Toobo\Bcp47Tag::new('en-CA-newfound')) === true);
+
+assert($tag->language() === 'en');
+assert($tag->extLang() === null);
+assert($tag->script() === null);
+assert($tag->region() === 'CA');
+assert($tag->variant() === 'newfound');
+assert($tag->extension() === null);
+assert($tag->privateUse() === null);
+assert($tag->isRtl() === false);
+
+assert((string) $tag === 'en-CA-newfound');
+
+assert(json_encode($tag) === '{"language":"en","region":"CA","variant":"newfound"}');
+```
+
+
+
+## Validation
+
+The `Bcp47Tag` class, as well as the `Bcp47::isValidTag()`, `Bcp47::filterTag()`, and 
+`Bcp47::splitTag()` functions, all do validation.
+
+The class throw on instantiation for invalid tags, while the functions returns, respectively,
+`false`, `null`, and an array with all empty items.
+
+The validation is not just about the _format_ but also the actual values. For example, `xy-IT`
+looks like a valid tag, but the language "xy" does not exist, so the the tag is not valid.
+
+The validation apply to all subtags (but "extension" and "privateUse"), and also _across_ subtags.
+For example, the tag `ca-valencia` is valid (_Valencia variant of the Catalan language_),
+but `en-valencia` is not, despite the language "en" and the variant "valencia" being valid per-se,
+because there is no "valencia" variant for the English language.
+
+
+
+## Normalization
+
+The `Bcp47Tag` class, as well as both `Bcp47::filterTag()` and `Bcp47::splitTag()` functions
+"normalize" the given tag.
+
+Normalization includes:
+- Replace deprecated values with the new accepted value, when available. For example, the region
+  code for the "Democratic Republic of the Congo" (formerly "Zaire") "ZR" is replaced with "CD".
+- Case normalization (all lowercase, but uppercase region and title-case script.
+- Replacement of numeric region codes with 2-chars alpha code, when available.
+- Replacement of 3-chars language code (ISO 639-3) with 2-chars code (ISO 636-1), when available.
+
+
+
+## FAQ
+
+- Why is `Bc47` an **enum**?
+
+This package's utility functions are stateless and pure PHP _functions_.
+
+However, plain PHP functions can't be autoloaded. By using a case-less PHP enum, we get autoloading,
+but unlike when using a class, we prevent anyone to extend or instantiate the class without 
+intervening on the runtime code.
+
+A case-less PHP enum is a _de facto_ autoload-enabling namespace for functions.
+
+
+
+## Installation
+
+Best served via Composer, the package name is `toobo/bcp47`.
+
+```bash
+composer require "toobo/bcp47:^1"
+```
+
+
+
+## Requirements
+
+BCP 47 requires PHP 8.3+, and requires via Composer:
+
+- "wikimedia/bcp-47-code" (GPL v2)
+
+When installed for development, it also requires via Composer:
+
+- "phpunit/phpunit" (BSD-3-Clause)
+- "inpsyde/php-coding-standards" (MIT)
+- "vimeo/psalm" (MIT)
