What are some best practices for organizing PHP files and folders for easier maintenance and development?

Organizing PHP files and folders in a logical and structured way can greatly improve the maintenance and development of a project. One common approach is to group related files together in directories based on functionality or feature, such as controllers, models, views, and helpers. This makes it easier to locate and work with specific components of the application.

// Example directory structure:
// /app
//   /controllers
//     UserController.php
//     ProductController.php
//   /models
//     User.php
//     Product.php
//   /views
//     user_view.php
//     product_view.php
//   /helpers
//     validation_helper.php
