anybody here can teach me how to work with remote files? for now im using ftp software to upload my updated files and view it in my web browser remotely. is there any way that when i save my file in the phped it will automatically upload like working in a local file?

sure.

basicly, you'll need you files in a local directory structured the same way as on the remote server. I mean that the same files should be located in the same subdirectories.
then you create a project and an FTP account in the IDE.
project will point to the local directory as a root of the project and your web server in the remote URL and remote path.

With this aproach you will be able to a) upload local files or directories to the server b) download back server's copies c) clicking run buttong with local file opened, you'll launch corresponding remote file on the server and certainly you'll be able to step with the debugger in the remote files.
