php composer autoload

I've hit a wall trying to I'm working with an scenario with autoloading namespaced classes in PHP 8.1 using Composer. I've set up a basic project structure where I have a directory `src/` for my PHP files and a `vendor/` directory for Composer dependencies. My `composer.json` looks like this: ```json { "autoload": { "psr-4": { "App\\": "src/" } } } ``` After running `composer dump-autoload`, I'm trying to instantiate a class from my `src/` directory: ```php // src/Example.php namespace App; class Example { public function greet() { return 'Hello, world!'; } } ``` And in my entry file, `index.php`, I have: ```php require 'vendor/autoload.php'; use App\Example; $example = new Example(); echo $example->greet(); ``` However, when I run `php index.php`, I get the following behavior: ``` PHP Fatal behavior: Uncaught behavior: Class 'App\Example' not found ``` I've double-checked the namespace and the file structure, and everything seems correct to me. I've also run `composer dump-autoload` multiple times and cleared the cache with `composer clear-cache`, but the behavior continues. Is there something I'm missing or misconfigured? Any insights would be greatly appreciated! This issue appeared after updating to Php 3.11. Any advice would be much appreciated.
