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". Interestingly it works as expected if the method got called with "ClassName::method". I send it here because fixing this could result in a hard to find BC break and it could be a good idea to handle this in 8.0. https://3v4l.org/NSdB8 class A {
    static function call() {
        self::method();
        $self = self::class;
        $self::method();
    }
    static function method() { echo static::class; }
} class B extends A {} B::call(); // displays "BA" instead of "AA" In case this is "Not a Bug" please explain to me why the result of "self::method()" is different then "$self = self::class; $self::method();". Thanks, Marc
