namespace App\Controllers;
use CodeIgniter\Controller;
use CodeIgniter\HTTP\CLIRequest;
use CodeIgniter\HTTP\IncomingRequest;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Psr\Log\LoggerInterface;
use App\Models\HeaderModel;

class BaseController extends Controller{
  
    protected $data=array();
    protected $session;
    protected $option ='';
    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger){
        parent::initController($request, $response, $logger);

        $this->db = \Config\Database::connect();
        $this->session = \Config\Services::session();

        $mSite= new HeaderModel();
        $this->option = $mSite->site_option_bottom();
        $this->data['site_name']        = $this->option->site_name;

i only write demo, if you do your project, you can write  method function to show

1. in BaseController.php 

PHP Code:

<?php
namespace App\Controllers;
use CodeIgniter\Controller;
use CodeIgniter\HTTP\CLIRequest;
use CodeIgniter\HTTP\IncomingRequest;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;
use Psr\Log\LoggerInterface;
use App\Models\HeaderModel;

class BaseController extends Controller{
  
    protected $data;
    protected $session;

    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger){
        parent::initController($request, $response, $logger);

        $this->data = \Config\Database::connect();
        $this->session = \Config\Services::session();

        $mSite = new HeaderModel();
        $data['test']= $mSite->site_option_bottom();
     //path view footer.php in your project
        return view('Site\footer',$data);
    }

    
} 


in footer.php we show this

PHP Code:

<?php

print_r($test); 
?>
