Accessing private from static method in PHP

Question

Why this works? I mean, accessing the private variable.

class Test {
    private $q = 0;
    public function __construct() {
        $this->q = 1;
    }
    public static function EpicConstruct() {
        $test = new self();
        $test->q = 2;
        return $test;
    }
}

$test = Test::EpicConstruct();

Think about it like a men's and women's locker room. Objects of the same class can see each other's privates. — Fabian Schmengler

Because you are accessing the member in the correct context, namely: the class that defines the private member.

So i can work with any object of this class this way? I think i understand how decorator pattern works now. Thanks!

@smsteel As long as it is the same class: yes. With the decorator pattern, not so much: as a decorator is a class that either extends the class, or, more typically, extends/implements a common supertype (some base class or interface). The former kind of decorator will only have access to members that are at least protected, the latter only to public members of the class (or protected members of the supertype).
