Bug description:get_called_class incorrect after call_user_func to a parent
static function
Description:
------------
When called from an instance function via call_user_func (or
call_user_func_array), the late static binding appears to not recognise an
explicit call to a parent static function and propagates the caller as the
called class rather than the callee.
When called "directly" the late static binding functions correctly.
To reiterate: there is an inconsistency here between the results with
P::test() and call_user_func('P::test') in the test script below. My
opinion is that this is a bug.
Tested with the script below in PHP 5.3 and PHP 5.4.15.
If this is the expected behaviour ("feature not a bug") then it should be
prominently documented (c.f. bug #47402)
Test script:
---------------
abstract class P {
static public function test() {
echo get_called_class();
}
}
class C extends P {
public static function runStatic() {
P::test();
call_user_func('P::test');
call_user_func(array('P', 'test'));
}
public function run() {
P::test();
call_user_func('P::test');
call_user_func(array('P', 'test'));
}
}
C::runStatic();
$c = new C();
$c->run();
Expected result:
----------------
Console output:
PPPPPP
Actual result:
--------------
Console output:
PPPPCC
