Calling function in a controller from a parameter sent by the user in PHP

I am building an application that from the information the user sends me on a GET I will run a function. EX:

//classe
class Page extends CI_Controller {

    public class index($param){ 
      //aqui estou procurando algo semelhante a $this->"$param"();
    }

    private class foo(){ echo 'foo'; }
    private class bar(){ echo 'bar'; }

}

For the above example, if my user sent to the function index('foo') he would have to perform the function $this->foo(). Could someone show me how I can do my job index() perform another function depending on the sent parameter?

    You need to create routes to your application, the controller should not be responsible for directing actions other than redirects in isolated cases. Here’s an example: http://laravel.com/docs/5.1/routing - It’s a bit boring to do without a framework, but it’s possible, I have a route system that I made for my own use and works as well as frameworks.

For you to do this is simple.

Let’s create a controller called for example test and inside him do what you need:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Teste extends CI_Controller {

    public function __construct(){

        parent::__construct();
    }

    public function ver($param){
        echo $this->$param();
    }
    private function foo(){
        echo 'foo';
    }
}

Go to the URL and pass the command as an example:

http://localhost/test/ver/foo

Will display

foo

if you want to create a controller to control every application and leave the URL organized, you can use Rotas, that is a good and easy way out:
