In object-oriented programming (OOP) in PHP, what steps are necessary to correctly call a method within a class instance like "zeitwandlung()"?

When calling a method within a class instance in PHP, you need to first create an instance of the class using the `new` keyword. Then, you can access the method using the arrow operator `->`. Make sure the method is defined within the class and is accessible (not private or protected) to be called from outside the class.

class MyClass {
    public function zeitwandlung() {
        // Method logic here
    }
}

// Creating an instance of the class
$obj = new MyClass();

// Calling the method
$obj->zeitwandlung();
