What are some best practices for using properties and objects in PHP?

When working with properties and objects in PHP, it is important to follow best practices to ensure clean and maintainable code. One best practice is to use visibility keywords (public, private, protected) to control access to properties within a class. Another is to use getter and setter methods to access and modify properties, instead of directly accessing them. Additionally, it is recommended to use type hinting to enforce data types for properties. 

class User {
    private $name;

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

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

$user = new User();
$user->setName('John Doe');
echo $user->getName();
