061a3c9c09The method has been renamed some time ago, but I haven't updated the documentation to cause less confusion. Now that I want to start updating the documentation, I switched the default branch on GitHub to the latest stable version, so I assume there will be less confusion in the documentation, and I can start updating the docs for the next version.

|
- `LanguageCode()`
|
|
- `LanguageCode("alpha-2"|"alpha-3" $set)`
|
|
|
|
Validates whether the input is language code based on [ISO 639][].
|

**This rule requires [sokil/php-isocodes][] and [sokil/php-isocodes-db-only][] to be installed.**

```php
|
|
v::languageCode()->isValid('pt'); // true
|
|
v::languageCode()->isValid('en'); // true
|
|
v::languageCode()->isValid('it'); // true
|
|
v::languageCode('alpha-3')->isValid('ita'); // true
|
|
v::languageCode('alpha-3')->isValid('eng'); // true
|
|
```
|
|
