How can interfaces be effectively used to manage class inheritance and method implementation in PHP, especially in cases where classes are dynamically created or modified?

Interfaces can be effectively used in PHP to manage class inheritance and method implementation by defining a contract that classes must adhere to. This allows for a clear separation of concerns and promotes code reusability. When classes are dynamically created or modified, interfaces ensure that the necessary methods are implemented, maintaining consistency across different classes.

// Define an interface that specifies the required methods
interface Animal {
    public function makeSound();
}

// Implement the interface in a class
class Dog implements Animal {
    public function makeSound() {
        echo "Woof! Woof!";
    }
}

// Create a new class dynamically and ensure it implements the interface
$newClass = new class implements Animal {
    public function makeSound() {
        echo "Meow! Meow!";
    }
};

// Call the makeSound method on both classes
$dog = new Dog();
$dog->makeSound();

$newClass->makeSound();
