What are the benefits of using interfaces in PHP for class implementation?

Using interfaces in PHP for class implementation allows for better organization and structure in your code. It helps to enforce a contract between classes, ensuring that certain methods are implemented in each class that implements the interface. This can help prevent errors and make your code more maintainable and scalable. 

<?php
// Define an interface
interface Animal {
    public function makeSound();
}

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

// Create an instance of the class
$dog = new Dog();
$dog->makeSound(); // Output: Woof! Woof!
?>
