What are some best practices for organizing and referencing files in a PHP project?

Organizing and referencing files in a PHP project is essential for maintaining a clean and manageable codebase. One best practice is to use a consistent folder structure, such as separating files by functionality or module. Another tip is to use namespaces to avoid naming conflicts and improve code readability. Additionally, using autoloading mechanisms like Composer can help streamline the file referencing process. 

// Example of organizing files using a consistent folder structure
// Create folders for different modules or functionalities
// For example, create a folder named 'controllers' for all controller files
// And a folder named 'models' for all model files

// Example of using namespaces to avoid naming conflicts
namespace MyProject\Controllers;

class UserController {
    // Controller logic here
}

// Example of using Composer for autoloading
// Add the following to your composer.json file
"autoload": {
    "psr-4": {
        "MyProject\\": "src/"
    }
}

// Run `composer dump-autoload` to generate the autoload files
// Now you can reference classes using their namespaces
use MyProject\Controllers\UserController;
$userController = new UserController();
