Description:
------------
---
From manual page: https://php.net/function.get-object-vars
---

I realize the code works as intended#1 however the documentation of get_object_vars does not mention that uninitialized object properties will not be returned.


#1: https://bugs.php.net/bug.php?id=79236

Test script:
---------------
class A {
    public function get() {
        var_dump(get_object_vars($this));
    }
}

class B extends A {
    public $foo;
    public $bar = 'bar';
    public string $baz;
}

$b = new B;

$b->get();

Expected result:
----------------
array(3) {
  ["foo"]=>
  NULL
  ["bar"]=>
  string(3) "bar"
  ["baz"]=>
  uninitialized // <- or something different?
}

Actual result:
--------------
array(2) {
  ["foo"]=>
  NULL
  ["bar"]=>
  string(3) "bar"
}

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The documentation states:

| Gets the accessible non-static properties of the given object
| according to scope.

$baz is not accessible[1], though.
