Answer 1

Well there are many ways to do this...
One such way, might be like...
Assume that example.php is the required Frontend so we will need a route to it.
In app\Config\Routes.php we need the entry
$routes->get('/example', 'Example::index');
This lets us use the URL your-site dot com/example
Now we need to decide how we want to use the functions in Base inside Example. So we could do the following...
<?php namespace App\Controllers;
class Example extends BaseController {
protected $base;
/**
* This is the main entry point for this example.
*/
public function index() {
$this->base = new Base(); // Create an instance
$this->myfunction();
}
public function myfunction() {
echo $this->base->header(); // Output from header
echo view('internet/swiatlowod'); // Output from local view
}
}
When and where you use new Base() is up to you, but you need to use before you need it (obviously).
You could do it in a constructor, you could do it in a parent class and extend it so it is common to a group of controllers.
It's up to you.
