/**
* Formatter provides a set of commonly used data formatting methods.
*
* The formatting methods provided by Formatter are all named in the form of `asXyz()`.
* The behavior of some of them may be configured via the properties of Formatter. For example,
* by configuring [[dateFormat]], one may control how [[asDate()]] formats the value into a date string.
*
* Formatter is configured as an application component in [[\yii\base\Application]] by default.
* You can access that instance via `Yii::$app->formatter`.
*
* The Formatter class is designed to format values according to a [[locale]]. For this feature to work
* the [PHP intl extension](http://php.net/manual/en/book.intl.php) has to be installed.
* Most of the methods however work also if the PHP intl extension is not installed by providing
* a fallback implementation. Without intl month and day names are in English only.
* Note that even if the intl extension is installed, formatting date and time values for years >=2038 or <=1901
* on 32bit systems will fall back to the PHP implementation because intl uses a 32bit UNIX timestamp internally.
* On a 64bit system the intl formatter is used in all cases if installed.
*
* > Note: The Formatter class is meant to be used for formatting values for display to users in different
* > languages and time zones. If you need to format a date or time in machine readable format, use the
* > PHP [date()](http://php.net/manual/en/function.date.php) function instead.
