如何使用laravel插入和上传多个文件？

Route::post('/upload', 'FileController@upload')->name('upload');

php artisan make:controller FileController

public function upload(Request $request)
{
    if ($request->hasFile('files')) {
        $files = $request->file('files');
        
        foreach ($files as $file) {
            $filename = $file->getClientOriginalName();
            $file->move(public_path('uploads'), $filename);
        }
        
        return "Files uploaded successfully!";
    }
    
    return "No files to upload!";
}

<form action="{{ route('upload') }}" method="POST" enctype="multipart/form-data">
    @csrf
    <input type="file" name="files[]" multiple>
    <button type="submit">Upload Files</button>
</form>

Route::get('/upload', function () {
    return view('upload');
});
