Question

I am trying to make a script in which different classes (e.g. Database, Utilities, Config) are all used to form one central Main class. I have tried extending a chain of them:

Main -> Utilities -> Database -> Configuration

But how can I set the different parts so that they can be called like this:

<?php

     $this->db->select("WAFFLES");
     echo($this->config->app_path);

?>

Answer 1

You need to declare each new object as variable in your Main Class like:

class Main{

    private $db = NULL;
    private $config = NULL;

    $this->db = new Database;
    $this->config = new Config;

}

etc.

While i’m not a professional coder i’ll considering a better approach than this. This kind of object-handling can cause a bloated main class and in the worst case you may face some performance issues.
