blanking out an array

hi, i need to be able to totally erase all the elements of an array after it is used in a script. Unfortunately, unset doesn't seem to be working for me since I have the elements of the array stored in a MySQL using the "serialize" function and not all of the code fragments (for lack of a better descriptive phrase) are deleted when I use unset. I've also tried setting each element to "" but that isn't working either. There must be a simple solution to this problem, does anyone have a suggestion? thanks! maria Maria B.
