How to call a function in helper from outside codeigniter (ci) - tried the solution from other stackoverflow links but doesn't work

Question

I have created a function in application/helpers/ which works fine when accessing from ci. Now I want to call the same function from outside ci i.e., from core PHP file. But I'm not able to do so.

Below is the approach tried.

Created a test.php outside ci and below is the code:

<?php
    $filepath = dirname(__FILE__);
    ob_start();
    require_once($filepath.'/ci/index.php');
    ob_get_clean();
    return $CI;
?>

In another core PHP file, test2.php, below is the code:

$CI = require_once('test.php');
echo $CI->config->item('base_url');
some_helper_function($param1, $param2);

Error message:

Fatal error: Call to a member function item() on a non-object in <path>/Utf8.php on line 47

Folder structure:

test.php
test2.php
ci/application/helpers/test_helper.php (contains some_helper_function())

Any suggestions?

where is the code for the function you want to get? What's the purpose of using `$CI` if you want to use it outside of CI isn't that like an oxymoron or something. — ArtisticPhoenix, Dec 20 '17 at 11:39
In test2.php, some_helper_function() is the function which is defined in application/helpers/ — Kalyan Srinivas Limkar, Dec 20 '17 at 11:41

Create a file and put the following code into it.

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

  if ( ! function_exists('test_function'))
  {
    function test_function()
    {
        //your functionality//
    }   
}

Save this to application/helpers/ . save it as "test_helper.php"

The first line exists to make sure the File cant be included and run from outside the Code Igniter.

Then in your controller or Model

$this->load->helper('test_helper');

You can use any function from that helper page.

Else

your-project-name\application\config\autoload.php

$autoload['helper'] = array('test_helper');

So that you can use that helper function in any controller or model. Not to initialize in each and every controller or model like previously said.

Here you have written the code on how to call helper function in controller/model. My requirement is to call the helper function outside the ci. – Kalyan Srinivas Limkar Dec 20 '17 at 11:52
Just include your helper page in which page you want to use that helper page function like given below like include('./application/helpers/test_helper.php'); and use that function in that page. – imlokeshs Dec 20 '17 at 11:57
$CI = require_once 'CI.php'; echo $CI->config->item('base_url'); // test CI instance /*Include like this and try */ – imlokeshs Dec 20 '17 at 12:12

My approach is from the above link (https://codeinphp.github.io/post/codeigniter-tip-accessing-codeigniter-instance-outside/). It's not working. – Kalyan Srinivas Limkar Dec 20 '17 at 12:18
