On the MSBWare.com site there's a new tutorial looking at the integration of the FCKeditor (a powerful web-based editor that works much like Word) with a MySQL database backend via PHP.
This article is intended to address the lack of documentation in integrating the FCKeditor with your MySQL database. Their tutorials show how to configure and use the editor, but how to get it to save to your database isn't addressed at all. While this article will utilize the MySQL DBMS, the concepts are the same for any DBMS.
They start with the download and install of the editor, including placing it in a page where it can be used (inclusion and configuration). The next step is to wrap the entire editor block in a form to make it submittable and, finally, write the update script to happen on submit. Complete code is included at the end of the tutorial.
