How to declare a class function outside the class or inside __construct()?

Question

PHP

Such task interests:
There is a certain class which will be modified each time. And to make it easy to do, I decided to separate the class functions into different folders.

config (главная папка)
-- link (папка функции для работы с link)
-- title (папка функции для работы с title)

etc.
With the help of a cycle that is in __construct()or outside the class itself, I load each file. But I don't know how to declare a function for this class to make this code work:

Class config {
   function __construct(){
      // здесь подгружаются файлы
   }
}
// или подгружать здесь
$config = new config();
$config->getLink('protocol');

How can this be implemented? If there are alternatives, I'm glad to know. The main thing is that all functions from different files work using one variable, like$config;

there is no such crutch that a pkheshnik cannot come up with.
- create a base abstract class, from which you inherit further

- runkit
- answer D' Normalization
but all this in this case did not fucking fall: it's more convenient to edit the class ( with autocomplete and other goodies), and not 100,500 separate functions, spread evenly on the disk.
