Codeigniter global variable within controller

Question

I have a controller with a couple of methods and they all have the same variable within them. I am looking for a way to have them share the same variable. What is the best way to do this?

What I have now:

class Example extends CI_Controller{
  public function test{
    $variable = "awesome";
  }

  public function demo{
    $variable = "awesome";
  }

}

Answer 1

How about...

class Example extends CI_Controller
{

  public $variable = "awesome";

  public function test()
  {
    echo $this->variable; // awesome
  }

  public function demo()
  {
    echo $this->variable; // awesome
  }

}
