How do I improve security on my site, what suggestions do people in the know have on this issue, I set up a programme it's working fairly smoothly and then something is altered either a variable name or in one instance the actual data capture so that the function end($array) was producing the first rather than the last element which obviously messed up the results, I really don't mind so much if I am messing about with my scripts which is usually what I do, but when people submit their data and that gets confused I do mind, It took me an entire day to figure out what had been altered, please offer suggestions, since I can't think of anyone or any reason for this activity it's not as if I have a million dollar site here, its just a game.
