Class Names can access non-static methods but cannot access non-static properties

### Code

```
<?php

class BaseClass {
 public $x = 10;
 public function __construct() {
 echo "BaseClass constructor". " ";
 }
}

class SubClass extends BaseClass {
 public function __construct() {
 BaseClass::__construct();
 echo "SubClass constructor" . " ";
 print parent::$x;
 }
}

(new SubClass());

?>

```
