Been Looking for This Capability for a Long Time

Hey, so I'm not sure what it's called which is why I'm asking.

Say you've got a webpage and you've finished and you want a client to be able to edit some areas of the site as far as text goes. How can you set it up so that there's a word document right next to the .html file that has a little snippet of text and if they edit the text in the document, the text on the site changes.

Thanks!

Thank you for the reply. I am aware of CMS, what i speaking about is something similar to


"<?php echo file_get_contents('path/to/mytextfile.txt'); ?>"


except in html. As in literally grab the text from a text file and display it on the page. CMS is the concept that it sounds like i'm askign about but i need this because i have a C++ program writing to a text file and i want to be able to graphically display the data in the text file on a webpage. Hope that makes sense?
