 Internationalization
 ====================
 Internationalization (I18N) refers to the process of designing a software application so that it can be adapted to
 various languages and regions without engineering changes. For Web applications, this is of particular importance
 because the potential users may be worldwide.
 Locale and Language
 -------------------
 There are two languages defined in Yii application: [[\yii\base\Application::$sourceLanguage|source language]] and
 [[\yii\base\Application::$language|target language]].
 Source language is the language original application messages are written in such as:
 ```php
 echo \Yii::t('app', 'I am a message!');
 ```
 > **Tip**: Default is English and it's not recommended to change it. The reason is that it's easier to find people translating from
 > English to any language than from non-English to non-English.
 Target language is what's currently used. It's defined in application configuration like the following:
 ```php
 // ...
 return array(
 	'id' => 'applicationID',
 	'basePath' => dirname(__DIR__),
 	'language' => 'ru_RU' // ← here!
 ```
 Later you can easily change it in runtime:
 ```php
 \Yii::$app->language = 'zh_CN';
 ```
 Basic message translation
 -------------------------
 Yii basic message translation in its basic variant works without additional PHP extension. What it does is finding a
 translation of the message from source language into target language. Message itself is specified as the second
 `\Yii::t` method parameter:
 ```php
 echo \Yii::t('app', 'This is a string to translate!');
 ```
 Yii tries to load approprite translation from one of the message sources defined via `i18n` component configuration.
 TBD: https://github.com/yiisoft/yii2/issues/930
 ### Named placeholders
 You can add parameters to a translation message that will be substituted with the corresponding value after translation.
 The format for this is to use curly brackets around the parameter name as you can see in the following example:
 ```php
 $username = 'Alexander';
 echo \Yii::t('app', 'Hello, {username}!', array(
 	'username' => $username,
 ));
 ```
 Note that the parameter assignment is without the brackets.
 ### Positional placeholders
 ```php
 $sum = 42;
 echo \Yii::t('app', 'Balance: {0}', $sum);
 ```
 > **Tip**: Try keep message strings meaningful and avoid using too many positional parameters. Remember that
 > translator has source string only so it should be obvious about what will replace each placeholder.
 Advanced placeholder formatting
 -------------------------------
 In order to use advanced features you need to install and enable [intl](http://www.php.net/manual/en/intro.intl.php) PHP
 extension. After installing and enabling it you will be able to use extended syntax for placeholders. Either short form
 `{placeholderName, argumentType}` that means default setting or full form `{placeholderName, argumentType, argumentStyle}`
 that allows you to specify formatting style.
 Full reference is [available at ICU website](http://icu-project.org/apiref/icu4c/classMessageFormat.html) but since it's
 a bit crypric we have our own reference below.
 ### Numbers
 ```php
 $sum = 42;
 echo \Yii::t('app', 'Balance: {0, number}', $sum);
 ```
 You can specify one of the built-in styles (`integer`, `currency`, `percent`):
 ```php
 $sum = 42;
 echo \Yii::t('app', 'Balance: {0, number, currency}', $sum);
 ```
 Or specify custom pattern:
 ```php
 $sum = 42;
 echo \Yii::t('app', 'Balance: {0, number, ,000,000000}', $sum);
 ```
 [Formatting reference](http://icu-project.org/apiref/icu4c/classicu_1_1DecimalFormat.html).
 ### Dates
 ```php
 echo \Yii::t('app', 'Today is {0, date}', time());
 ```
 Built in formats (`short`, `medium`, `long`, `full`):
 ```php
 echo \Yii::t('app', 'Today is {0, date, short}', time());
 ```
 Custom pattern:
 ```php
 echo \Yii::t('app', 'Today is {0, date, YYYY-MM-dd}', time());
 ```
 [Formatting reference](http://icu-project.org/apiref/icu4c/classicu_1_1SimpleDateFormat.html).
 ### Time
 ```php
 echo \Yii::t('app', 'It is {0, time}', time());
 ```
 Built in formats (`short`, `medium`, `long`, `full`):
 ```php
 echo \Yii::t('app', 'It is {0, time, short}', time());
 ```
 Custom pattern:
 ```php
 echo \Yii::t('app', 'It is {0, date, HH:mm}', time());
 ```
 [Formatting reference](http://icu-project.org/apiref/icu4c/classicu_1_1SimpleDateFormat.html).
 ### Spellout
 ```php
 echo \Yii::t('app', '{n,number} is spelled as {n, spellout}', array(
 	'n' => 42,
 ));
 ```
 ### Ordinal
 ```php
 echo \Yii::t('app', 'You are {n, ordinal} visitor here!', array(
 	'n' => 42,
 ));
 ```
 Will produce "You are 42nd visitor here!".
 ### Duration
 ```php
 echo \Yii::t('app', 'You are here for {n, duration} already!', array(
 	'n' => 42,
 ));
 ```
 Will produce "You are here for 47 sec. already!".
 ### Plurals
 Different languages have different ways to inflect plurals. Some rules are very complex so it's very handy that this
 functionality is provided without the need to specify inflection rule. Instead it only requires your input of inflected
 word in certain situations.
 ```php
 echo \Yii::t('app', 'There {n, plural, =0{are no cats} =1{is one cat} other{are # cats}}!', array(
 	'n' => 0,
 ));
 ```
 Will give us "There are no cats!".
 In the plural rule arguments above `=0` means exactly zero, `=1` stands for exactly one `other` is for any other number.
 `#` is replaced with the `n` argument value. It's not that simple for languages other than English. Here's an example
 for Russian:
 ```
 Здесь {n, plural, =0{котов нет} =1{есть один кот} one{# кот} few{# кота} many{# котов} other{# кота}}!
 ```
 In the above it worth mentioning that `=1` matches exactly `n = 1` while `one` matches `21` or `101`.
 To learn which inflection forms you should specify for your language you can referer to
 [rules reference at unicode.org](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html).
 ### Selections
 You can select phrases based on keywords. The pattern in this case specifies how to map keywords to phrases and
 provides a default phrase.
 ```php
 echo \Yii::t('app', '{name} is {gender} and {gender, select, female{she} male{he} other{it}} loves Yii!', array(
 	'name' => 'Snoopy',
 	'gender' => 'dog',
 ));
 ```
 Will produce "Snoopy is dog and it loves Yii!".
 In the expression `female` and `male` are possible values. `other` handler values that do not match. Strings inside
 brackets are sub-expressions so could be just a string or a string with more placeholders.
 Formatters
 ----------
 In order to use formatters you need to install and enable [intl](http://www.php.net/manual/en/intro.intl.php) PHP
 extension.
