Is it possible to use type hinting with anonymous classes in PHP, and if so, how can it be implemented?

Type hinting with anonymous classes in PHP is possible by using the `object` type declaration. This allows you to specify the expected type of an anonymous class when passing it as a parameter to a function or method. By using the `object` type hint, you can ensure that only instances of a specific class or interface are accepted.

interface MyInterface {
    public function myMethod(): void;
}

function processObject(object $obj) {
    $obj->myMethod();
}

$anonClass = new class implements MyInterface {
    public function myMethod(): void {
        echo "Hello from anonymous class!\n";
    }
};

processObject($anonClass);
