Bug #77154 [NEW]: private property inheritance discussion
From: jpauli
Operating system: *
PHP version: master-Git-2018-11-14 (Git)
Package: Class/Object related
Bug Type: Bug
Bug description:private property inheritance discussion
Description:
------------
This behavior is wether right or wrong ; let's debate :
Test script:
---------------
class A {
private static $foo = 'Afoo';
function foo() { return static::$foo; }
}
class B extends A { }
$b = new B;
echo $b->foo();
Expected result:
----------------
PHP <= 7.3 shows :
Fatal error: Uncaught Error: Cannot access property B::$foo in XXXX
PHP-master shows :
the string 'Afoo'
Actual result:
--------------
What should be the right behavior ?
Considering that the same use-case using non-static attribute, and non
static classic $this accesses the attributes just all right in all PHP
versions
Should private static attributes be inherited, or not ?
