How can magic setter/getter methods impact object conversion in PHP?

Magic setter/getter methods can impact object conversion in PHP by allowing dynamic access to properties that may not exist explicitly in the object. This can be useful for handling conversions between different data formats or structures. By implementing magic methods like `__get` and `__set`, we can intercept property access and modification, enabling us to customize how object properties are handled during conversion processes. 

class DataConverter {
    private $data = [];

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

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

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

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

// Example usage
$converter = new DataConverter();
$converter->name = 'John Doe';
$converter->age = 30;

$dataArray = $converter->toArray();
var_dump($dataArray);

$converter->fromArray(['name' => 'Jane Smith', 'age' => 25]);
var_dump($converter->toArray());
