Ok I am new to php and need a little help. I want to make a script to rate an article and let someone leave comments. When the script is called with and article ID# I want to check if the file fileID# exists and if not create it. The database fields would basicly be rating, userID, and comment. With userID being the Primary key. How would I test for existence of the database and create it if necessary? (also if I allow anon users would IP address make a good key? would IP address be a unique value?) Thanks!
