implementing Abstract Class Initialization Using Interfaces in PHP 8.1
I'm refactoring my project and I've searched everywhere and can't find a clear answer. I'm relatively new to this, so bear with me... I'm running into a question where my abstract class isn't initializing correctly when I implement an interface in PHP 8.1. I have an abstract class `Animal` that requires a method `makeSound()`, and a class `Dog` that implements the `Animal` class and the `SoundMaker` interface. However, I keep getting an behavior saying `want to instantiate abstract class Animal` when I try to create a new instance of `Dog`. Here’s the relevant code: ```php interface SoundMaker { public function makeSound(); } abstract class Animal implements SoundMaker { abstract public function makeSound(); } class Dog extends Animal { public function makeSound() { return 'Bark'; } } $dog = new Dog(); // This line throws the behavior ``` I've confirmed that I am not trying to instantiate the `Animal` class directly. I also checked the PHP version with `phpinfo()` and confirmed it’s 8.1. I even tried implementing the `SoundMaker` interface directly in the `Dog` class instead of through `Animal`, but that didn’t help either. The behavior continues. Could this be related to some specific configuration in how I'm using abstract classes with interfaces, or is there something else I might be overlooking? Any help would be appreciated! This is part of a larger service I'm building. What are your experiences with this?
