在同一名称空间的多个文件中导入相同的PHP类

I would like to Use the same class Helper, located at App\Helpers\Helper, in two different files within the same namespace.

For example:

Class A:

<?php

namespace App\Services;

Use Helper;

class A {...}

Class B:

<?php

namespace App\Services;

Use Helper;

class B {...}

However, this is not allowed. The error is:

Cannot use App\Helpers\Helper as Helper because the name is already in use

I could rename the Helper class in my second file and say Use Helper as SomethingElse, but this seems like a messy solution especially if I want to use this Helper in many more than two classes.

Is there a workaround for this?

    You most probably already have an included class that goes by that name, the likely problem is that you have a class by that name in another namespace (and said class has been included). You can use both classes (from different namespaces with the same name) by aliasing or using fully qualified names of the classes.
    Read this properly.
