Bug description:Late Static Bindings
Description:
------------
If I call method of the class "B" that implements class "A" that uses
static, under some class "C" it tries to get static property of the "C",
but not of the "B". And if I try to call B::inst() not under some class it
works fine.
Test script:
---------------
class A
{
public static $_a = null;
private function __construct()
{}
private function __clone()
{}
public function inst()
{
if (is_null(static::$_a))
{
static::$_a = new static();
}
return static::$_a;
}
}
class B extends A
{
}
class C
{
public function __construct()
{
B::inst();
}
}
Expected result:
----------------
B::$_a
Actual result:
--------------
Fatal error: Access to undeclared static property: C::$_a
