How does using objects instead of arrays in PHP code help in maintaining data integrity and correctness?

Using objects instead of arrays in PHP code helps maintain data integrity and correctness by providing a structured way to store and access data. Objects allow for encapsulation of data and behavior, which helps prevent accidental modification of data and ensures that data is accessed and manipulated in a controlled manner. Additionally, objects can have defined properties and methods, making it easier to enforce data validation and business rules. 

class User {
    private $firstName;
    private $lastName;
    
    public function __construct($firstName, $lastName) {
        $this->firstName = $firstName;
        $this->lastName = $lastName;
    }
    
    public function getFullName() {
        return $this->firstName . ' ' . $this->lastName;
    }
}

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