Laravel Get Config Variable
提问by giuseppe
In Laravel 5.0 (I know it is old, but the project is not mine) I set in config/app.php
在 Laravel 5.0（我知道它很旧，但该项目不是我的）中 config/app.php
return [
...
'languages' => ['en','it'],
...
]
Then, I have a blade wrapper in resources/views/frontend/includes/menus/guest.blade.php
然后，我有一个刀片包装 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?
但是，Laravel 说 foreach 没有有效的参数，这意味着 Config::get('languages') 返回 null。我无法在 app.php 中设置自定义变量？

Laravel has a helper function for config which allows you to avoid instantiating a Configinstance each time you access a value.
Laravel 有一个用于 config 的辅助函数，它允许您避免Config每次访问一个值时实例化一个实例。
Simply use:
只需使用：
config('app.languages');
回答by Jonathan
You need to change it to:
您需要将其更改为：
@foreach (Config::get('app.languages') as $lang => $language).
@foreach (Config::get('app.languages') as $lang => $language).
Treat the first segment of your lookup as the files under /config, in this case app.phpcorresponds to Config::get('app.*')
将查找的第一段视为 下的文件/config，在这种情况下app.php对应于Config::get('app.*')
