The code has been refactored to improve readability and maintainability. The main changes include removing unnecessary condition checks, simplifying the flow of control, and reorganizing the code blocks for better logical grouping. This should make it easier to understand and modify in the future.
The cache directory name for the Twig environment has been updated. The previous hyphen-separated name 'twig-cache' has been replaced with an underscore-separated one, 'twig_cache'. This change ensures consistency in naming conventions across the project.
A new .htaccess file has been added to handle URL rewriting. The index.php file has been significantly refactored for improved readability and performance. A large portion of the original code was moved to a separate script.php file, which is now executed from within index.php. This change simplifies the main entry point of the application and separates concerns more effectively. Additionally, minor changes were made to cache handling in script.php.
