Hey, I've written a script in PHP that writes data into a MySQL database upon request, but what I'd also like to include is a script that will go in after the request is made, and check to make sure that the same entry does not already exist... and I have no clue where to start. I've never tried to do anything like this before, and am not sure what to do. If I could get some ideas from anyone it would be greatly appreciated. Thanks!
