What are some best practices for accessing and manipulating object attributes in PHP classes?

When accessing and manipulating object attributes in PHP classes, it is considered a best practice to encapsulate the attributes by making them private or protected and providing public getter and setter methods to access and modify them. This helps to maintain data integrity, improve code readability, and allow for easier future modifications. 

class User {
    private $name;
    
    public function getName() {
        return $this->name;
    }
    
    public function setName($name) {
        $this->name = $name;
    }
}

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