In what scenarios would it be beneficial to use Composer for autoloading in PHP, and what are the advantages of this approach over manual implementation?

When working on a PHP project with multiple classes and dependencies, using Composer for autoloading can greatly simplify the process of including and managing these classes. Composer's autoloader follows the PSR-4 standard, which allows for efficient and automatic class loading based on namespaces. This approach eliminates the need for manual inclusion of each class file, making the codebase cleaner and more maintainable. 

```php
// composer.json file
{
    "autoload": {
        "psr-4": {
            "App\\": "src/"
        }
    }
}
```

After defining the PSR-4 autoloading configuration in the `composer.json` file, run `composer dump-autoload` to generate the autoloader files. From there, you can simply use namespaces to access classes without worrying about manual inclusion.
