Codeigniter: __construct variable into my another function

I need to print first segment variable in my function from __construct, but I get error:

Code:

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

class Main extends CI_Controller {

    public $data = array();

    public function __construct()
    {
        parent::__construct();
        $data['seg'] = $this->uri->segment(1);
        $data['seg'] == 'en' ? $data['seg'] = 'en' : $data['seg'] = 'ge';
    }

    public function index()
    {
        echo "test";
    }

    public function Test()
    {
        echo $data['seg'] . " - TEST";
    }

}

/* End of file  */
/* Location: ./application/controllers/Main.php */

Error:

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: data

Filename: controllers/Main.php
Line Number: 21
Backtrace:

As Manual http://php.net/manual/en/language.oop5.visibility.php

You can access public variable by 

$this->data['seg']=..........;

You have to use $this to set or get value of $data which is in class scope. I have fixed your code here, give a try.

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

class Main extends CI_Controller
{
    public $data = array();

    public function __construct()
    {
        parent::__construct();

        $this->data['seg'] = $this->uri->segment(1);
        $this->data['seg'] == 'en' ? $this->data['seg'] = 'en' : $this->data['seg'] = 'ge';
    }

    public function index()
    {
        echo "test";
    }

    public function Test()
    {
        echo $this->data['seg'] . " - TEST";
    }
}
