The I18n library provides a I18n
service locator that can be used for setting
the current locale, building translation bundles and translating messages.
Additionally, it provides the Time
and Number
classes which can be used to
output dates, currencies and any numbers in the right format for the specified locale.
Internally, the I18n
class uses Aura.Intl.
Getting familiar with it will help you understand how to build and manipulate translation bundles,
should you wish to create them manually instead of using the conventions this library uses.
use Cake\I18n\I18n;
I18n::locale('en_US');
use Cake\Core\Configure;
Configure::write('App.paths.locales', ['/path/with/trailing/slash/']);
Please refer to the [CakePHP Manual](http://book.cakephp.org/3.0/en/core-libraries/internationalization-and-localization.html#language-files) for details
about expected folder structure and file naming.
### Translating a Message
```php
echo __(
'Hi {0,string}, your balance on the {1,date} is {2,number,currency}',
['Charles', '2014-01-13 11:12:00', 1354.37]
);
// Returns
Hi Charles, your balance on the Jan 13, 2014, 11:12 AM is $ 1,354.37
use Cake\I18n\I18n;
use Aura\Intl\Package;
I18n::translator('animals', 'fr_FR', function () {
$package = new Package(
'default', // The formatting strategy (ICU)
'default', // The fallback domain
);
$package->setMessages([
'Dog' => 'Chien',
'Cat' => 'Chat',
'Bird' => 'Oiseau'
...
]);
return $package;
});
I18n::locale('fr_FR');
__d('animals', 'Dog'); // Returns "Chien"
$time = Time::now();
echo $time; // shows '4/20/14, 10:10 PM' for the en-US locale
echo Number::format(100100100);
echo Number::currency(123456.7890, 'EUR');
// outputs €123,456.79
Please make sure you check the official I18n documentation.
The documentation for the Time class contains instructions on how to configure and output time strings for selected locales.
The documentation for the Number
class shows how to
use the Number
class for displaying numbers in specific locales.
