I don't think the first option is equivalent:

class C {
    function printType() {
        echo "__CLASS__ is " . __CLASS__ . "\n";
        echo "get_class is " . get_class($this) . "\n";
    }
}

class D extends C {
    function printTypeInChild() {
        echo "__CLASS__ is " . __CLASS__ . "\n";
        echo "get_class is " . get_class($this) . "\n";
    }
}

(new D)->printType();
(new D)->printTypeInChild();

// Output is:
__CLASS__ is C
get_class is D
__CLASS__ is D
get_class is D

And unless I'm missing something, the second option doesn't appear
usable with static methods, which is also a problem with
get_parent_class()

What would the equivalent code get_parent_class() for static methods? e.g.

class A {}

class B extends A {
    public static function foo() {
        echo get_parent_class() . " \n";
    }
}
b::foo();

cheers
