How to Create and Use Custom Helpers in CodeIgniter?

Creating Custom Helpers in CodeIgniter

In CodeIgniter, it's often necessary to perform repetitive tasks with arrays. While extending existing helpers is an option, sometimes creating a custom helper is more suitable. Here's how to create and use a custom helper called "loops_helper.php":

Creating the Helper File

Create a new PHP file called loops_helper.php and place the following code in it:

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

if (!function_exists('test_method')) {
    function test_method($var = '') {
        return $var;
    }
}

Save the file in the application/helpers directory.

Using the Helper

To use the custom helper, you can include it in your controllers, models, or views using the load helper function:

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

echo test_method('Hello World');

Autoloading the Helper

If you need to use the helper in multiple locations, you can add it to the autoload configuration file in application/config/autoload.php:

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