How to make the application configuration available in all plug-in classes in the form of an array?

Question

PHP

In general, there is an application configuration array:

$config = [
        'logotext' => 'USER Application Name', 
        'base_dir' => BASE_DIR, 
        'db' => [
            'file' => BASE_DIR . 'db/database.sqlite',
        ],
        'router'=> [
            'path'=>true,
            'action'=>'index',
            'rules'=> [],
        ],
    ];
// Старт приложения:
$app = new Application($config);
echo $app->run();

Application abstract class - System:

abstract class System {
public $config;
public function __construct($config=null) 
    {
        $this->_setConfig($config); // Преобразую Массив конфига в обьекты, чисто для красоты ($this->config->paramName->subParamName)
        $this->init();
    }

private function _setConfig($config) 
    {
        $this->config = $this->_toObject($config);
    }
public function router($class='Router') 
    {
        return new $class($this->config->router);    
    }

}

The main application class Application inherited from the abstract System class:

class Application extends System {
function __construct($config=null) 
    {
        parent::__construct($config);            
    }

}

Of course, I don’t know at all exactly how much this is all correctly implemented, do not scold too much. The problem is that every time you have to pass the configuration ($this->config) when creating instances of auxiliary classes inside the main Application class or in System (via the constructor), which also want to use a common configuration array. For example, I will make a new Data class, which, for example, will be of the model type, this class will need information on how to access the database

class Data {
function getConfigDSNString()
{
return; // Вернуть какую либо строку из конфигурации в качестве примера передачи конфиг массива в класс
}
}

As an option, of course, you can use a separate Config class for this, in which you can declare some static get() method and call something like Config::get('dbDSN');
What other options are there to not bind classes to configuration transfer through constructors or through an additional static class Config?
