This is expected behaviour given my understanding of how late static binding works:
If there is a chain of “self::” calls that ultimately ends in “static::someMethod”, then PHP behaves as if every preceding call was a call to “static::”, not “self::”. In your second call you’re explicitly overriding that resolution by changing using (self::class)::someMethod, which PHP always treats as A::someMethod, thus producing the expected output. > On Mar 8, 2020, at 4:48 AM, Marc <marc@mabe.berlin> wrote: > > Hi, > > I have reported a bug in Mai 2019 but did not get any response here > https://bugs.php.net/bug.php?id=77985. > > > The problem is that "static::class" as well as "get_called_class()" used > within a method resolves to a different class if this method was called with > "self::method".
