What are the potential pitfalls of using multiple arrays in PHP classes for data manipulation?

Using multiple arrays in PHP classes for data manipulation can lead to increased complexity, potential data inconsistency, and difficulty in maintaining and debugging the code. To solve this issue, consider using a single multidimensional array to store related data together, making it easier to manage and manipulate the data within the class. 

class DataManipulator {
    private $data = [];

    public function setData($key, $value) {
        $this->data[$key] = $value;
    }

    public function getData($key) {
        return $this->data[$key] ?? null;
    }
}

// Example usage
$manipulator = new DataManipulator();
$manipulator->setData('name', 'John Doe');
$manipulator->setData('age', 30);

echo $manipulator->getData('name'); // Output: John Doe
echo $manipulator->getData('age'); // Output: 30
