Easy steps:

1. Direct download: https://github.com/briannesbitt/Carbon/blob/master/src/Carbon/Carbon.php

2. Put Carbon.php at application/libraries

3. Create Mcarbon.php

   <?php
   
   if ( ! defined('BASEPATH')) exit('No direct script access allowed');
   require_once dirname(__FILE__) . '/Carbon.php';
   
   use Carbon\Carbon;
   
   class Mcarbon extends Carbon
   {}
   

4. Put this in your Controller

   $this->load->library ( 'Mcarbon' ); 
   

5. Call Carbon method in any function. Example:

   <?php
   
   $dt =Mcarbon::createFromDate(2018,2,13,null);
   var_dump($dt->year);
   var_dump($dt->month);
   var_dump($dt->day);
   var_dump($dt->hour);

Here is another method for Codeigniter 3:

1. Install using Composer (I don't explain here how install Composer):

   • Open the terminal
   • Go to the root folder of your Codeigniter project and type:

     composer require nesbot/carbon ^2

   • It should install Carbon 2.x in the vendor/nestbot/Carbon folder
   • Remove the ˆ2 to install the latest 1.x version (when writing this answer)

2. Update Codeigniter config file to autoload the component:

   • Open application/config/config.php and change:

     $config['composer_autoload'] = FALSE;

     to:

     $config['composer_autoload'] = FCPATH.'/vendor/autoload.php';

3. Create a Codeigniter library for Carbon:

   • Create the application/libraries/Carbon_lib.php file:

   <?php
   
   if ( ! defined('BASEPATH')) exit('No direct script access allowed');
   
   use Carbon\Carbon;
   
   public function __construct($time = null, $tz = null) {
   
     parent::__construct($time, $tz);
   
   }

4. Load the library in your controller, model...:

   $this->load->library('carbon_lib');

5. Use the library as you would with Carbon:

   $carbon = $this->carbon_lib;
   $carbon->addDay();
   //Get the SQL date and date/time format
   $carbon->toDateString();
   $carbon->toDateTimeString();
   //And to create an immutable object
   $carbonImmutable = $this->carbon_lib->toImmutable();
   ...

See Carbon website for more details.

Follow the steps for Codeigniter 3:

1. Install carbon via composer

   composer require nesbot/carbon

2. Update index.php, Add this line

   require 'vendor/autoload.php';

3. In your controller add this line at the top.

   use Carbon\Carbon;

Now you can use carbon functionalities. example:

Carbon::now();
