How can method signatures be abstracted in PHP interfaces without using objects?

In PHP interfaces, method signatures can be abstracted without using objects by simply defining the method signatures without implementing them. This allows classes that implement the interface to define the actual implementation of the methods while ensuring they adhere to the specified signature. 

<?php

interface MyInterface {
    public function myMethod();
}

class MyClass implements MyInterface {
    public function myMethod() {
        // Implement the method here
    }
}
