PHP Curl upload/download functions

Hello, I would need a upload fonctions in php (curl) with an account management for each file host. Also i would need a download functions in php with an account management for [login to view URL], [login to view URL], [login to view URL] and [login to view URL] . The file host list (for upload functions): Megaupload Rapidshare [login to view URL] (no account management needed) [login to view URL] (no account management needed) Fileserve Filesonic Hotfile Easy-Share The upload functions need to be called like that : name_of_file_host( $path_to_file, $login, $password) And the script return the download link. For the download functions : hostname_dowload($url, $download_repertory, $file_name, $login, $password) $dowload_repertory = where to download file on the server $file_name = file name when saved (important)
