class DefaultTranslator in Plug 7

Simple translator implementation that simply replaces the parameters in the message IDs.

Example usage:

$translator = new DefaultTranslator();

echo $translator->trans( 'This is a {{ var }}.', array('{{ var }}' => 'donkey') );

// -> This is a donkey.

echo $translator->transChoice( 'This is {{ count }} donkey.|These are {{ count }} donkeys.', 3, array('{{ count }}' => 'three') );

// -> These are three donkeys.

This translator does not support message catalogs, translation domains or locales. Instead, it implements a subset of the capabilities of {@link \Symfony\Component\Translation\Translator} and can be used in places where translation is not required by default but should be optional.

   * Interpolates the given choice message by choosing a variant according to a number.
   *
   * The variants are passed in the message ID using the format
   * "<singular>|<plural>". "<singular>" is chosen if the passed $number is
   * exactly 1. "<plural>" is chosen otherwise.
   *
   * This format is consistent with the format supported by
   * {@link \Symfony\Component\Translation\Translator}, but it does not
   * have the same expressiveness. While Translator supports intervals in
   * message translations, which are needed for languages other than English,
   * this translator does not. You should use Translator or a custom
   * implementation of {@link \Symfony\Component\Translation\TranslatorInterface} if you need this or similar
   * functionality.
