php composer autoloading namespaces PHP

I've searched everywhere and can't find a clear answer... I'm experiencing an scenario with autoloading in my PHP 8.2 application that uses Composer for dependency management. I've set up my namespaces in a way that matches the directory structure, but when I attempt to instantiate a class, I get a `Class 'MyApp\Controllers\HomeController' not found` behavior. I've verified that the `composer.json` file is correctly configured with the proper autoload settings: ```json { "autoload": { "psr-4": { "MyApp\\": "src/" } } } ``` After running `composer dump-autoload`, I confirmed that the file structure under the `src` directory is as follows: ``` src/ ├── Controllers/ │ └── HomeController.php ├── Models/ │ └── User.php └── Services/ └── UserService.php ``` The `HomeController.php` file has the following code: ```php <?php namespace MyApp\Controllers; class HomeController { public function index() { return 'Hello, World!'; } } ``` From my `index.php`, I'm trying to use: ```php <?php require 'vendor/autoload.php'; use MyApp\Controllers\HomeController; $controller = new HomeController(); echo $controller->index(); ``` I've also tried clearing the Composer cache and regenerating the autoload files, but the behavior continues. I checked for typos in namespace declarations and file naming conventions, and everything seems to be in order. Additionally, running `composer validate` reveals no issues. Is there something I'm missing regarding the PSR-4 autoloading or class naming conventions in PHP 8.2? Any suggestions on what I could check further would be greatly appreciated. This is part of a larger API I'm building.
