Weird behavior with uninitialized typed properties and __set/__get


Seems calling a constructor is triggering __set magic for uninitialized typed properties. So it does not matter the property is public or private/protected.

I suppose the problem is __set/__get called before __construct when a type is given to a property. Also I if remove __get then I get object(acme\Options)#1 (1) { ["stack"]=> array(1) { ["stack"]=> array(1) { ["one"]=> int(1) } } }.

Uninitialized typed properties

While throwing when try to access to any uninitialized typed property (eg: $o->x == null),
the codes below are just causing notice.

BTW, error message is so weird. We were expecting something like this;

k-gun

// Java
class Foo { Integer i; }

class Test {
    public static void main(String args[]) {
        System.out.println(new Foo().i == null);
    }
}

// JavaScript

k-gun

<?php
// ok, cos converted to ?int = null, right?
function foo(int $i = null) {}

// ok, all ok, right?
$a = new class {
    public $i;
    public function check(): bool {
        return ($this->i != null);
    }
