Bug description: get_class_vars does not include visible private variable
looking at subclass
Description:
------------
Even after bug #45862, #46761 and #46795 there is something really weird
going on with get_class_vars(). It seems to be the consensus of the
developers that get_class_vars() should return all properties of the given
class that are _visible_ from the context calling get_class_vars()
(nevermind that the docs claim "returns ... public properties of the class"
(see #46795)). (Also, #31543 seems to contradict everything else)
But get_class_vars() does not return visible private properties when
invoked on a subclass.
In the attached code, the second call to dumpClass should return
'private_a', as $private_a would still be visible in methods in A, even if
the object in question actually is of type B.
As a side note, I find it a bit strange that the behaviour of
get_class_vars() function changed between 5.2.6 and 5.2.7 (it broke a
real-world inhouse app here, for example) :)
Reproduce code:
---------------
<?php
class A {
private $private_a;
public static function dumpClass($class) {
print_r(get_class_vars($class));
}
}
class B extends A {
private $private_b;
}
A::dumpClass('A');
A::dumpClass('B');
Expected result:
----------------
Array
(
[private_a] =>
)
Array
(
[private_a] =>
)
Actual result:
--------------
Array
(
[private_a] =>
)
Array
(
)
