Website/Interface Design

I am not sure how exactly this can be accomplished, so I placed it under "website design" and "PHP" as they seem to match the request best. I run a "virtual pet" type of site where people can adopt what is basically an image of a creature. The creatures all have numerical "stats" such as strength, intelligence, etc., which I randomly generate when I create each creature for someone to adopt. Once players adopt a creature, they can buy items with virtual currency, and these items can raise the creature's "stats". However, I don't want to have to edit the HTML for each and every creature's page when someone increases one stat. What I would like is some kind of interface/site front where I can log in and access a database of every creature and its stats, and can easily edit the numerical values of the stats when I view an entry. It would also be great if it would be possible for the creature's owner to view a webpage where the stats were displayed after I updated them. Thank you!
