Check method/function exist with Controller

Hi guys,

can anyone please help, how can i check if method/funcion exist within class/controller? say:

PHP Code:

class User extends CI_Controller {
    public function __construct() {
      parent::__construct();
    }

    public function login() {
       ...
    }
} 


the idea is, i want to check function "login()" if exist and execute.

hope someone could help.

Thanks in advanced 

Depending where in the application you want this to happen, you can use the _remap function from CI
https://ellislab.com/codeigniter/user-gu...llers.html

PHP Code:

public function _remap($method, $params = array())
{
    $method = 'process_'.$method;
    if (method_exists($this, $method))
    {
        return call_user_func_array(array($this, $method), $params);
    }
    show_404();
} 


What is your idea ?
Where you want to make this check?

You can use the _remap method from CI as described here:

The following short example shows you a quick usage

PHP Code:

class User extends CI_Controller {
    public function __construct() {
      parent::__construct();
    }

    function _remap($method)
    {
        if(method_exists($this,$method))
        {
            call_user_func(array($this, $method));
            return false;
        }
        else
        {
            echo 'Method not found!';
        }
    }

    // .... your methods ....

} 


Ahh, thank you guys. very much appreciated all your help.
