您需要将其更改为：
@foreach (Config::get('app.languages') as $lang => $language) .
将查找的第一个段视为/config下的文件，在本例中app.php对应于Config::get('app.*')
如果不明显，也可以使用helper函数config()而不是Config::get()。

Laravel有一个用于config的helper函数，它允许你避免在每次访问一个值时示例化一个Config示例。
只需用途：

config('app.languages');

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

print_r($languages);
