What is the recommended approach for handling file uploads and form data validation in PHP to avoid complications like passing the $_FILES[] array?

When handling file uploads and form data validation in PHP, it is recommended to use a library like Symfony's HttpFoundation component or Laravel's request validation to abstract the handling of $_FILES[] array and ensure secure file uploads. These libraries provide methods to handle file uploads and validate form data without directly accessing the $_FILES[] array, reducing the risk of complications and improving security. 

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\File\UploadedFile;

$request = Request::createFromGlobals();

// Handle file upload
$file = $request->files->get('file');
if ($file instanceof UploadedFile) {
    $file->move('/path/to/upload/directory', $file->getClientOriginalName());
}

// Validate form data
$validatedData = $request->request->all();
// Perform validation checks on $validatedData
