CodeIgniter call function within the same class

Question

I am trying to do this code in my CodeIgniter application :

Answer 1

OK, I agree this is a MAJOR goof-up; comes from lack of OOP understanding;

<?php
class Inventory extends Controller {
    function current_stock() {
        //do something
    }

    function add_stock() {
        //do something-else
        $this->current_stock();
        // and we called the other method here!
    }
}

Just that I didn"t expect it to be so easy

Answer 2

Just use $this->your_function_name();

Answer 3

Only $this->nameFunction();
example

<?php 

class Hello extends CI_Controller{

 public function index(){
  $this->hello();
 }
public function hello(){
  return "hello world";
 }
}
