Could someone answer a few questions about CKEditor?

Hello!

Let me first say that I am not a javascript coder at all! I'm a php coder at an intermediate level at best. I had asked on another forum about online editors that a user could use and I was pointed to this one and TinyMCE (which I received zero help).

I don't do well with just pointing me to the doc. Some of it makes sense and some of it doesn't since my grasp on javascript is near zero! I'm good with working examples and doc .. that works least I can pick about what's it's doing.

The point; and that is before I invest a lot of time on getting this to go will I be able to do the following and with what degree of difficulty.

Can the editor read in a file? Lets name the file someContents.html and that file contains some html markup. Once in the editor the user can change the contents of that file and then save new/edited contents back to someContents.html I do sort of the same thing right now with PHP but I have no style or formatting abilities like the editor does. And in the end I can have the viewable webpage read in someContents.html dynamically into the webpage.

I appreciate the help in any size/shape or form!

Best Regards!
