foreach in models and controller

Helper

PHP Code:

<?php defined('BASEPATH') OR exit('No direct script access allowed');

function infoServer($name) {
    $CI = get_instance();
    $CI->load->model('informations');
    $CI->informations->info_server($name);
} 


Model

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Informations extends MY_Model {
    public function __construct() {
        parent::__construct();

    }
    public function info_server($name) {
        $db = $this->load->database('site', TRUE);
        $db    ->select('value')
                        ->from('arcor_server_setting')
            ->where('name', $name);
        $query_info_view = $db->get('');
        foreach ($query_info_view->result() as $row){
           echo $row->value;
        }
    }
} 


MY_Controller

PHP Code:

class MY_Controller extends CI_Controller {
        public function __construct(){
                parent::__construct();
                $this->information_server();
        }
        public function information_server() {
                $this->load->helper('infoserver');
        }
      
} 


In the same way I have an My_Model with the same content.

When I use infoServer('with the name of value') The result is printed on the top page. But not where I would actually. Dentrol and variables or functions inside. Only at the top.

While if I use it in a template it works perfectly.

Any solution?

I want to use the function so that when you call me the exact result, which it does, but it should work this way:

This
$variable = 'hello';
and this
$variable = infoServer('with the name of value');
They should be the same.

While at the time if I use the function produces the result I described before.

Thanks for the support.
