In the context of object-oriented programming, how important is it to differentiate between a Model Class and a Model Instance for clarity and maintainability?

Differentiating between a Model Class and a Model Instance is crucial in object-oriented programming to maintain clarity and ensure maintainability of the code. A Model Class represents the blueprint or template for creating instances of that class, while a Model Instance is a specific object created from that class. By clearly defining and understanding the distinction between the two, developers can easily manage and manipulate data within their application. 

class User {
    private $name;

    public function __construct($name) {
        $this->name = $name;
    }

    public function getName() {
        return $this->name;
    }
}

// Creating a Model Instance
$user1 = new User('John Doe');
echo $user1->getName(); // Output: John Doe
