Get all FUNCTIONS name from all CONTROLLERS in Codeigniter

Question

Hello I am trying to get all FUNCTIONS name from all CONTROLLERS in Codeigniter Well I am able to get all CONTROLLER names in array but am failed to get all functions of all controllers. I only get functions names of current controller in which I am writing the function.

I am fetching function names by $class_methods=get_class_methods(new classname());

If I tried it globally I get directory error.

For avail list of all controller with its method use this library:

<?php
if (!defined('BASEPATH'))
    exit('No direct script access allowed');
/***
 * File: (Codeigniterapp)/libraries/Controllerlist.php
 * 
 * A simple library to list all your controllers with their methods.
 * This library will return an array with controllers and methods
 * 
 * The library will scan the "controller" directory and (in case of) one (1) subdirectory level deep
 * for controllers
 * 
 * Usage in one of your controllers:
 * 
 * $this->load->library('controllerlist');
 * print_r($this->controllerlist->getControllers());
 *

            }
        }   
    }
}
// EOF

Save it in library folder

Than load this library into your controller

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

print_r($this->controllerlist->getControllers());

Now you will get all controller list with its method.

if you have any question please ask me.
