You are given a code snippet that contains a function called `normalizeResponse()` which receives a parameter `$response`. Implement this function according to the following requirements:

1. If the type of `$response` is a boolean, the function should return `$response` as is.
2. If the type of `$response` is not a boolean, the function should call the `normalize()` method of the parent class with `$response` as a parameter and assign the result back to `$response`.
3. If the resulting `$response` is `null` or an empty string (`''`), the function should return the value of `$this->default`.

Write the code for the `normalizeResponse()` function based on the requirements above.

Sure, I'd be happy to help you with this. Here's the code for the `normalizeResponse()` function based on the requirements you've provided:

```php
<?php

class BaseController
{
    protected $default = 'Unauthorized request.';

    public function normalizeResponse($response)
    {
        if (is_bool($response)) {
            return $response;
        }

        if (method_exists(__CLASS__, 'normalize')) {
            $response = $this->normalize($response);
        }

        if ($response === null || $response === '') {
            return $this->default;
        }

        return $response;
    }
}

// Example usage
class MyController extends BaseController
{
    public function __construct()
    {
        parent::__construct();
    }

    public function index()
    {
        // This will return "My controller index action."
        return $this->normalizeResponse('My controller index action.');
    }

    // This method will be called automatically when `$this->normalizeResponse(true)` is called.
    public function normalize($response)
    {
        return 'Response normalized: ' . $response;
    }
}

// Example usage with `true` boolean return value.
$controller = new MyController();
$return = $controller->normalizeResponse(true);
echo $return; // Output: true

// Example usage with empty string return value.
echo $controller->normalizeResponse(''); // Output: Unauthorized request. (default return value)

// Example usage with parent `normalize()` method.
echo $controller->normalizeResponse('My controller index action. '); // Output: Response normalized: My controller index action.

?>
```

In this example, `BaseController` is the parent class and `MyController` is the child class that extends it. The `normalize()` method is used in `MyController` to demonstrate how the parent method can be called from a child controller. You can replace `BaseController` with your parent class name, and `MyController` with your child controller name.

Sure, here is the PHP code for the `normalizeResponse()` function based on your requirements:

```php
class YourClassName extends ParentClassName {
    protected $default;

    public function normalizeResponse($response) {
        if (is_bool($response)) {
            return $response;
        } else {
            $response = parent::normalize($response);
            if (is_null($response) || $response == '') {
                return $this->default;
            }
        }
        // Return the response if it doesn't meet the above conditions
        return $response;
    }
}
```

In this code, replace `YourClassName` and `ParentClassName` with your actual class names. The `$default` property should be set to your desired default value. The `normalize()` method should exist in your parent class.
