Implementing Internet Protocols with PHP - The FTP Application
(Page 2 of 4 )
The application that we are going to create will implement the FTP protocol in a way that is as capable as possible using the functions listed in the previous section. The main purpose of an FTP client is to enable file transfer on a network. This includes downloading, uploading, removing, and traversing the directory structure of a drive. Our application will do all of this. Below is the code for the cascading style sheet that I designed for the FTP client application:

Copy and paste this code into a new document and save it as ftp.css . Don’t worry if you don’t understand the code; it is just styles that I’ve put together to make the presentation of the FTP user interface easier to read and understand.
