The Laravel Lang class provides a convenient way of retrieving strings in various languages, allowing you to easily support multiple languages within your application.

Language Files

Language strings are stored in files within the app/lang directory. Within this directory there should be a subdirectory for each language supported by the application.


Language files simply return an array of keyed strings. For example:

Example Language File


return array(
	'welcome' => 'Welcome to our application'

The default language for your application is stored in the app/config/app.php configuration file. You may change the active language at any time using the App::setLocale method:

Changing The Default Language At Runtime


Basic Usage

Retrieving Lines From A Language File

echo Lang::get('messages.welcome');

The first segment of the string passed to the get method is the name of the language file, and the second is the name of the line that should be retrieved.

Note: If a language line does not exist, the key will be returned by the get method.

You may also use the trans helper function, which is an alias for the Lang::get method.

echo trans('messages.welcome');

Making Replacements In Lines

You may also define place-holders in your language lines:

'welcome' => 'Welcome, :name',

Then, pass a second argument of replacements to the Lang::get method:

echo Lang::get('messages.welcome', array('name' => 'Dayle'));

Determine If A Language File Contains A Line

if (Lang::has('messages.welcome'))


Pluralization is a complex problem, as different languages have a variety of complex rules for pluralization. You may easily manage this in your language files. By using a "pipe" character, you may separate the singular and plural forms of a string:

'apples' => 'There is one apple|There are many apples',

You may then use the Lang::choice method to retrieve the line:

echo Lang::choice('messages.apples', 10);

Since the Laravel translator is powered by the Symfony Translation component, you may also create more explicit pluralization rules easily:

'apples' => '{0} There are none|[1,19] There are some|[20,Inf] There are many',
