How can a PHP developer effectively incorporate object-oriented programming techniques?

To effectively incorporate object-oriented programming techniques in PHP, a developer can create classes to represent entities, use inheritance to create relationships between classes, utilize interfaces for defining common behaviors, and implement encapsulation to restrict access to class properties and methods. 

// Example of creating a class to represent an entity
class User {
    private $username;
    private $email;

    public function __construct($username, $email) {
        $this->username = $username;
        $this->email = $email;
    }

    public function getUsername() {
        return $this->username;
    }

    public function getEmail() {
        return $this->email;
    }
}

// Example of creating an instance of the User class
$user = new User('john_doe', 'john.doe@example.com');
echo $user->getUsername(); // Output: john_doe
echo $user->getEmail(); // Output: john.doe@example.com
