Here is a high level overview of how namespaces work in PHP to try and help you understand this and give you a solution to your problem.
下面是对命名空间在 PHP 中如何工作的高级概述，以尝试帮助您理解这一点并为您提供解决问题的方法。
<?php
// This is the namespace of this file, as Laravel 5 uses PSR-4 and the
// App namespace is mapped to the folder 'app' the folder structure is
// app/Http/Controllers
namespace App\Http\Controllers;
// Use statements. You can include classes you wish to use without having
// to reference them by namespace when you use them further on in this
// namespaces scope.
use App\Subscribe;
class MyController extends BaseController
{
public function postSubscribe()
{
// You can now use the Subscribe model without its namespace
// as you referenced it by its namespace in a use statement.
$subscribe = new Subscribe();
// If you want to use a class that is not referenced in a use
// statement then you must reference it by its full namespace.
$otherModel = new \App\Models\Other\Namespace\OtherModel();
// Note the prefixed \ to App. This denotes that PHP should get this
// class from the root namespace. If you leave this off, you will
// reference a namespace relative to the current namespace.
}

You can try this, Simply use it :
你可以试试这个，只需使用它：
$subscribe = new App\Subscribe;
回答by Alp Altunel
Use App\Subscribe;.
使用App\Subscribe;.
Then you can use $subscribe = new Subscribe;in your code.
然后你可以$subscribe = new Subscribe;在你的代码中使用。
