	"elephant": "{{count}} elephant",
	"elephant_0": "no elephants",
	"elephant_2": "{{count}} elephants",

	"spiderWithCount" : "{{count}} spider",

	"spiderWithCount_plural_0" : "no spiders"
}

echo  i18next::getTranslation('animal.cat', array('count' => 2));
echo  i18next::getTranslation('animal.cat', 2);

Output:

   2 cats
   2 cats

echo  i18next::getTranslation('animal.elephant', array('count' => 0));
echo  i18next::getTranslation('animal.elephant', array('count' => 1));
echo  i18next::getTranslation('animal.elephant', array('count' => 2));
echo  i18next::getTranslation('animal.elephant', array('count' => 100));

Context

By providing a context you can differ translations. Eg. useful to provide gender specific translations.

"people":{
   "friend" : "A friend",
   "friend_female" : "A girlfriend",
   "friend_female_plural" : "{{count}} girlfriends",
   "friend_male" : "A boyfriend",
   "friend_male_0" : "no boyfriend",
   "friend_male_plural" : "{{count}} boyfriends"
}

echo  i18next::getTranslation('people.friend');
echo  i18next::getTranslation('people.friend', array('context' => 'female'));
echo  i18next::getTranslation('people.friend', array('count' => 2, 'context' => 'female'));
echo  i18next::getTranslation('people.friend', array('count' => 0, 'context' => 'male'));
echo  i18next::getTranslation('people.friend', array('count' => 1, 'context' => 'male'));
echo  i18next::getTranslation('people.friend', array('count' => 33, 'context' => 'male'));

Output:

   A friend
   A girlfirend
   2 girlfriends
   no boyfriends
   A boyfriend
   33 boyfriends

i18next::init('en', 'my/path/');
// loads my/path/translation.json

You can also use variables and split namespaces and languages to different files.

i18next::init('en', 'languages/__lng__/__ns__.json');
// loads languages/en/common.json, languages/fi/common.json, etc...

Method throws an exception if no files are found or the json can not be parsed.

mixed i18next::getTranslation( string $key [, array $variables ] );

Returns translated string by key.

i18next::getTranslation('common.cat', array('count' => 2, 'lng' => 'fi'));
