从嵌套类中访问类变量

My class structure is as follows,

Class Core{
      public $Variable = "Test";

      Class SubClass{
            // functions, etc

      }

      // functions etc
}

I need to access the variable $Variable from within the SubClass class, but I cannot think of a way to do it. I have tried $this->this->Variable without success.

Edit While this is incorrect syntax, this is how my class system is setup (and is achieved using includes).

    Assuming you had a proper inheritance model set up, you could use parent::. But your code as-is is a flat-out syntax error. You cannot nest classes like that.

    Class Core {
       public $var = 'test';
    }
    
    Class SubClass Extends Core {
       function foo() {
          $localvar = parent::$var;
       }
    }
    

    comment followup:

    Perhaps something more like this?

    class Core {
        public $Variable = 'foo';
        function __construct() {
           $this->subclass = new SubClass($this->variable);
        }
    }
    
    class SubClass {
        public $coreVariable;
        function __construct(&$var) {
           $this->coreVariable = $var;
        }
    }
