PHP Bug Type: Scripting Engine problem
Bug description: call_user_func propagating the scope while it didn't in 5_2
Description:
------------
Depending on the context and the callback, call_user_func didn't propagate
$this in 5_2. It now does in 5_3. Not sure which one is more correct, but
there is definitely a potential BC break here.
Reproduce code:
---------------
<?php
class A {
public function test() {
B::foo();
call_user_func(array("B", "foo"));
}
}
class B extends A {
public function foo() {
var_dump($this);
}
}
$b = new B; $b->test();
?>
Expected result:
----------------
// 5_2's output
object(B)#1 (0) {
}
NULL
Actual result:
--------------
// 5_3's output
object(B)#1 (0) {
}
object(B)#1 (0) {
}
