Laravel Get Config Variable

You need to change it to:

@foreach (Config::get('app.languages') as $lang => $language).

Treat the first segment of your lookup as the files under /config, in this case app.php corresponds to Config::get('app.*')

If it wasn't obvious, you can use the helper function config() rather than Config::get() as well.

Laravel has a helper function for config which allows you to avoid instantiating a Config instance each time you access a value.

Simply use:

config('app.languages');
