Twig

For using twig need extends your class from Plugin_Name\Includes\Controller

//admin/admin.php

use Plugin_Name\Includes\Conroller;

class Admin extends Controller {

    private $options;

    public function __constuct() {
        parent::__constuct( __DIR__ ); // __DIR__ - path to the directory where your views folder is located. You can use several directories passing them to an array.
        $this->options = get_option('plugin_name');
    }
    
    public function page_options() {
        $options = 
        $this->render( 'page-options', [
            'options' => $this->options;
        ]
    }

}

# admin/views/page-options.twig #
{{ dump(options) }}

Autoload

WordPress uses its style guide. Class Autoload will automatically load classes if you follow the spelling of namespaces.

Namespace should describe the location of your class in the plugin. For example: namespace Plugin_Name\Front; means the file is located plugin-name/front/file

Each world in class name should be a capital letter. The file name should be the same as the class name, but in lower case and between the words a hyphen -. For example: class Some_Class filename will be some-class.php
