Laravel插入var里面的get函数

Am i doing it wrong, i tried to insert a value inside a global function.

$servz = $revz->service;
$amount = Config::get("prices.".$servz."[0]");

I expect it to be : $amount = Config::get("prices.A1[0]");

Try using the helper to set and get, it uses array notation and is a little easier to follow. So to set a timezone for example:

  config(['app.timezone' => 'America/Chicago']);

and to get, just:

$value = config('app.timezone');

From the docs - pretty good explanation there.
