Laravel Get Config Variable

Question

In Laravel 5.0 I have set in config/app.php this:

return [
//...
'languages' => ['en','it'],
//...
]

Then, I have a blade wrapper in resources/views/frontend/includes/menus/guest.blade.php

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

But, Laravel says that foreach has no valid argument, which means that Config::get('languages') returns null. I can't set custom variables in app.php?

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.

Have you cached your config? php artisan config:clear

Thank you, I did it and now work. However, config in cache??I would prefer Cake to Laravel...

I promise you, in the long run, you'll prefer Laravel. 5.0 is quite old now. If you can, use 5.5 It is the latest LTS version

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');

What is the most common way to test code that uses an environment variable in this way. Normally i would guess dependency injection, however i don't see how that would work here.

$languages = config('app.languages');

print_r($languages);

This only duplicates Luke's much earlier answer.

To also add to what n3storm said, if you creat a new config file and you want to call it on your blade.php, it should be

<h1>{{config('file_name.variable_name')}}</h1>

with above code, everything should work.
