What are some best practices for organizing and accessing nested data in PHP objects?

When dealing with nested data in PHP objects, it is essential to have a clear and organized structure to easily access and manipulate the data. One best practice is to use object-oriented programming principles to create classes and methods that handle the nested data efficiently. Additionally, utilizing arrays and loops can help iterate through the nested data and access specific elements as needed. 

class NestedDataHandler {
    private $data;

    public function __construct($data) {
        $this->data = $data;
    }

    public function getData() {
        return $this->data;
    }

    public function getValue($key) {
        $keys = explode('.', $key);
        $current = $this->data;

        foreach ($keys as $k) {
            if (isset($current[$k])) {
                $current = $current[$k];
            } else {
                return null;
            }
        }

        return $current;
    }
}

// Example usage
$data = [
    'user' => [
        'name' => 'John Doe',
        'email' => 'john.doe@example.com',
        'address' => [
            'street' => '123 Main St',
            'city' => 'New York',
            'zip' => '10001'
        ]
    ]
];

$nestedDataHandler = new NestedDataHandler($data);

// Get user's name
echo $nestedDataHandler->getValue('user.name'); // Output: John Doe

// Get user's city
echo $nestedDataHandler->getValue('user.address.city'); // Output: New York
