     $value) {
            // Using the hash function with a defined algorithm (e.g., sha256)
            $result[$key] = hash('sha256', serialize($value));
        }
        return $result;
    }

    // Example usage
    $data = [
        "item1" => "value1",
        "item2" => [1, 2, 3],
        "item3" => "value3"
    ];

    $hashedData = hashArray($data);
    print_r($hashedData);
    ?>
