Fat-Free vs PHP-MVC: What are the differences?

# Introduction
Fat-Free and PHP-MVC are two popular PHP frameworks used for web development. While they both follow the MVC (Model-View-Controller) architecture, there are key differences that set them apart.

1. **Routing System**: Fat-Free uses a routing system based on regular expressions, allowing for more flexibility in defining routes compared to PHP-MVC, which follows a more traditional route mapping approach.
   
2. **Built-in Features**: Fat-Free provides out-of-the-box features such as Caching, Encryption, and Error handling, while in PHP-MVC, these functionalities need to be implemented manually or through additional libraries.

3. **Performance**: Fat-Free is known for its lightweight nature and high performance due to its minimalistic design, making it suitable for smaller projects or microservices. In contrast, PHP-MVC can be more resource-intensive, especially for larger applications.

4. **Configuration**: Fat-Free uses a simple configuration file where settings can be easily defined, while PHP-MVC may require more complex configuration setups depending on the project requirements.

5. **Template Engine**: PHP-MVC often relies on third-party template engines like Twig or Smarty for rendering views, while Fat-Free has its own built-in template engine, making it simpler to manage the presentation layer.

6. **Community and Support**: PHP-MVC has a larger community and more extensive documentation compared to Fat-Free, making it easier to find help and resources when working on projects using this framework.

In Summary, Fat-Free and PHP-MVC differ in their routing system, built-in features, performance, configuration, template engine, and community support. Each framework has its strengths and weaknesses, catering to different project requirements and developer preferences.
