php - Include html from remote server Edit then save on remote server -

let me begin with, english not native tong. there gonna miss-pelt words/sentences.

explaining situation:

i have bought script lot of money allows me put in root directory , edit static html documents specific tags. saves changes direct on html. use old clients bought website me wile ago. (static html css websites)

now dont want put script on own webserver, practically giving away script put lot of time in.

the plan

now plan put on own server next website. script allows me save through ftp connection. save possible save remote server. manage make simple user script let client log in php gets ftp information sql server "ftp save function".

but real question
