Bug description:Inheriting static function with static variable defined in a trait.
Description:
------------
There is a difference between inheriting static function with static
variable
defined in a trait of a base class and the same function defined in a base
class
directly.
Test script:
---------------
<?php
trait Foo {
static public function theSameFunc() {
static $var = NULL;
if (is_null($var)) $var = get_called_class();
return $var;
}
}
class A {
use Foo;
//static public function theSameFunc() {
// static $var = NULL;
// if (is_null($var)) $var = get_called_class();
// return $var;
//}
}
class B extends A {}
class C extends B {}
var_dump(A::theSameFunc());
var_dump(B::theSameFunc());
var_dump(C::theSameFunc());
class D extends C {}
class E extends D {}
class F extends E {}
var_dump(D::theSameFunc());
var_dump(E::theSameFunc());
var_dump(F::theSameFunc());
?>
Expected result:
----------------
string(1) "A"
string(1) "B"
string(1) "C"
string(1) "D"
string(1) "E"
string(1) "F"
Actual result:
--------------
string(1) "A"
string(1) "B"
string(1) "C"
string(1) "C"
string(1) "C"
string(1) "C"
