Your task is to implement a custom exception class in PHP that can be used to handle a specific runtime scenario. Create a class called `GoalReachedNotEnough` within the namespace `P4lv\ExcelGoalSeek\Exception`. This exception class should extend the built-in `RuntimeException` class.

Sure, I can help you with that. Here's a basic implementation of a custom exception class `GoalReachedNotEnough` in PHP, extended from `RuntimeException`. Please replace `GoalReachedNotEnough` with the name you want to use.

```php
<?php

namespace P4lv\ExcelGoalSeek\Exception;

use Exception;
use RuntimeException;

class GoalReachedNotEnough extends RuntimeException
{
    public function __construct(int $statusCode, string $message = '')
    {
        $this->statusCode = $statusCode;
        parent::__construct('Goal reached, but there are not enough values to complete the goal seek. ' . $message, $statusCode);
    }
}
```

In this implementation, `__construct` method is used to set the custom message and status code. The `statusCode` property can be a custom error code or a status code as per your requirements, and you can add more functionality to this class as needed.

You'll also need to update the `use` statement at the top of the file with your namespace and the exception class.

Sure, here's how you can create the custom exception class `GoalReachedNotEnough` in PHP within the namespace `P4lv\ExcelGoalSeek\Exception`:

```php
<?php

namespace P4lv\ExcelGoalSeek\Exception;

class GoalReachedNotEnough extends \RuntimeException
{
    public function __construct($message = "", $code = 0, \Throwable $previous = null)
    {
        // You can customize the error message here if needed
        $message = 'Goal reached but not enough iterations: ' . $message;

        parent::__construct($message, $code, $previous);
    }
}
```

This class extends the built-in `RuntimeException` class and overrides the constructor to allow for a custom error message. The `$message`, `$code`, and `$previous` parameters are optional and can be used to provide more details about the error.
