Access Variable Variable in ForEach From Outside Class

Question

I have a class that for the sake of example to make it easier to understand, takes an associative array, loops over it and assigns a variable name, based on key, and assigns it the value. This works fine in the class:

class showItems {

  static public function list(){
    foreach ($list as $name => $value) {
      $$name = $value;
    }
    // This works here
    echo $title; // This is the variable I want Which is being set in the foreach.
    break;

  }

}

The above class works fine, and $title can be echo'd. However, accessing that variable from outside of the class is where I don't have any luck. I've tried all types of processes I can think of.

$showItems = new showItems();
$showItems::list();

// Cannot grasp what I need to do here to echo the value I want.
$showItems::list()->$title; // This returns "Trying to get property of non-object"

?>

What does function showItems return?

Don't echo inside your list method.
You can reach your static list method through your class like this: showItems::list()
You are not passing a parameter to your list method, which is highly strange, as you have stated that it

takes an associative array

Your $list seems to be uninitialized inside your list method.
No need to instantiate your class if you only want to call a static method.
It is unclear what you are trying to do, so please, rephrase your question and write a comment to this post, so I will edit my answer to help you further.

It's quite clear, inside the foreach loop running inside the class, I can echo $title, so I know it's working, don't worry about the rest of the code. However - how do I actually retrieve that $title variable from outside of the class?

You can create a static member called $title inside your showItems class and create a getter for it. However, if something seemingly "works", that is not necessarily correct.

Do something like $TestItems=new testItems() then TestItems->list() and make the list function return $title.
