Summary: get_called_class incorrect after call_user_func to a
parent static function
Status: Open

Still not fixed in PHP 7.2.7-1+ubuntu18.04.1+deb.sury.org+1 (cli) (built: Jun 22 2018 08:45:49) (
NTS ).
Seems like the call_user_func() (and call_user_func_array()) works the same way as the
forward_static_call().

Forgot to add:
static::test() in both runStatic() and run() produces the output C, as would be expected through the
LSB.

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
