After I upload .doc files to my database is it possible to edit these for example changing text colour, adding a background colour etc and then being able to print this back to a browser using php and MySQL ?
any help would be greatly appreciated
The only thing you can do is fetch teh doc out of the database, edit it with an editor, and upload it back into the database.
This is one of the reasons why storing binary data (files) in a database is such a very very bad idea.
