PSR-4 Autoloader无法识别子文件夹结构中的类

Question

I am using Slim PHP as the underlaying framework for my app and composer autoload for the loading of my classes. In composer i have this psr-4 configuration:

 "psr-4": {
      "App\\": "app/classes/"
    }

All my classes are in /app/classes/ folder.

In my classes folder i have all common classes but module specific classes i have in sub folders.

From my ../classes/connect.php file i am having this method under the corresponding namespace:

namespace App;
class connect
{
  public function authenticate(){
    office\AuthenticationManager::acquireAppToken(200);
  }
}

In my subfolder ../classes/office/ i have a file called office.php with this method:

namespace App\office;
    class AuthenticationManager
    {
        public function acquireAppToken($tid)
        {
           \App\APIManager\RequestManager::sendPostRequest();
        }
    }

The above method is calling another method which is located in ../classes/api.php

The namespace in that file is

namespace App\APIManager;

The problem is that when calling on this last method i get the following error: "\\App\\APIManager\\RequestManager" not found...

I already tried to solve this with composer dump-autoload, but it did not help. Why is this error happening?

Answer 1

If you want to have a class named RequestManager in App\\APIManager namespace, then it must be located in APIManager/RequestManager.php file.

It also applies to the AuthenticationManager class, which should be moved to office/AuthenticationManager.php

Have a look at PSR-4 examples .
