PHP Trait call inherited function

Question

I have got a trait

trait Foo{

    protected static function foo(){
        echo 'Hello';
    }
}

and a class

class Bar{
    use Foo;

    private static function foo(){
        Foo::foo();

        echo ' World!';
    }
}

I cannot use Foo:foo(). What can I do to achieve the desired effect?

EDIT

Using

use Foo {foo as parentFoo}

private static function foo(){

    self::parentFoo();

    echo ' World!';

}

did the trick.

Answer 1

You can do something like this:

class Bar{

    use Foo {
        Foo::foo as foofoo;
    }

    private static function foo(){

        self::foofoo();

        echo ' World!';

    }

}
