Folder Upload

Hello Everyone, I'm creating a script and I'm not able to do one part of it. So I've decided to ask for help!!! 1) I need a php page were the user can select a folder from his computer (similar to "<input type="file" name="fotos[]" />", but selecting a folder, not a file) 2) Upload from the user's computer to the server all files from the selected folder (saving all in the folder "/imagensUpload") I need to upload multiple files => 200, 300, 400 or even 500 files in one request, so it's not acceptable use "<input type="file" name="fotos[]" />". Please, just offer if you know how to do it.
