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";
 }
}

• jondavidjohn: possible duplicate of PHP/CodeIgniter - Setting variables in __construct(), but they're not accessible from other functions
• MJVC: Misleading. Global usually means application scope not class/instance scope.

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
 }
}

• ThomasReggi: What is the difference between declaring $variable public or private?
• 65Fbef05: You can access a public property in an object directly via Object::variable or $object->variable - A private property you cannot and can only access it from withing the class.
• jondavidjohn: public/private controls whether or not inheriting classes derived from this one have direct access to this property.
