Hi Artisan,

Hello, all! In this article, we will talk about codeigniter custom library example. you can see create custom library in codeigniter. you will learn make custom library in codeigniter. I explained simply about codeigniter 3 load custom library example. So, let's follow a few steps to create an example of create custom library file in codeigniter.

Sometimes, we might be require to make custom library in php codeigniter project. so we can load custom library quickly and use that functions.

you can see step by step tutorial of creating custom library file in codeigniter 3 application. just follow bellow few steps to create your own library for your codeigniter 3 project.

first let's create library file in libraries folder of your app.

application/libraries/Mylibrary.php

<?php
    
class Mylibrary {
    
  function my_first_call()
  {
    return 'Hello, ItSolutionStuff.com';
  }
    
}
   
?>

now create one route for testing so let's register one route for calling custom library function.

application/config/routes.php

$route['my-library'] = "MyLibraryController";

Now just create controller for testing call of created custom library in codeigniter app. let's create controller like as bellow:

application/controllers/MyLibraryController.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
   
class MyLibraryController extends CI_Controller {
     
    /**
     * Get All Data from this method.
     *
     * @return Response
    */
    public function index()
    {
        $this->load->library('mylibrary');
      
        echo $this->mylibrary->my_first_call();
    }
