Answer 1

Use codeigniter-kint and a custom file for global Functions. This will give you a more helpful and beautiful Output like:

File: application/helpers/globalfunctions_helper.php

load->library('kint');
       return @Kint::dump($value);   
      }
    }
    if(!function_exists('dp')){
      function dp($value=false)
      {
       $CI = get_instance();
       $CI->load->library('kint');
       Kint::dump($value);
       die();
      }
    }
