PHP: is it possible to access static methods as follows: Object :: ChildObject :: method ()?

Question

In JS, you can access methods this way: ParentObject.ChildObject.ChildObjMethod () - can this be done in PHP?

Answer 1

::can be used to access static class members. But you can also access instantiated child objects in PHP using the regular arrow ->:

$parent->child->child_method();

<?php
    class Foo
    {
        static public $bar;

        static public function initStaticMembers()
        {
            self::$bar = new Bar();     
        }
    }

    class Bar
    {
        public function method()
        {
            echo "Hello World\n";
        }

    }

    Foo::initStaticMembers();
    Foo::$bar->method();

    Object::ChildObject::method();

    $o = Object::ChildObject;
