File upload via FTP application via PHP

Hi, I have script which is all about uploading files to FTP account via PHP I just need to modify it based on the following points 1) To add upload process bar shows the uploading percentage or something indicating that it’s still uploading the file selected like .GIF image. 2) To add check where if the uploaded file name is already available then ask to overwrite or cancel. 3) Capability to copy/move files and folders. 4) Share folder owner can delete files from his share folder 5) To make user can upload files in share folder with permission 0664 and folders with permission 0755 NOT like the main directory which is 0700 for files and folders done by the script. 6) Other white-listed users can view/download/copy files and folders from other users share folder but they can't delete or move. 7) Some minor design fix I will provide FTP account for you to upload the modified files and test Regards Zoombay
