How can changes to $this->name or attribute values affect the data structure in the PHP code?

When changes are made to `$this->name` or attribute values in PHP code, it can affect the data structure by altering the values stored in the object's properties. To ensure that changes to these values do not inadvertently affect the data structure, it is important to properly validate and sanitize user input before assigning it to object properties. 

class User {
    private $name;

    public function setName($name) {
        // Validate and sanitize user input before assigning it to $this->name
        $this->name = filter_var($name, FILTER_SANITIZE_STRING);
    }

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

$user = new User();
$user->setName($_POST['name']);
echo $user->getName(); // Output sanitized user input
