What is the piece of Code i need to let people add

their info...

I have an html tool.
But i need a piece of code i think so people can add on tinymc and then save.... 

This will get you started:

<?php

If you need more than that, you'll have to do a better job of explaining what you want.

I don't understand either.  Perhaps if you ask in your native language and let us translate it will be the better way to get help.
