    min and max functions

    If I have a series of integers, how do I get the minimum (or maximum) value
    NOT equaled to 0??

      Are they in an array? comma separated string? other?

              You could stuff the values into an array and run array_filter on it
              (removing 0 values). Then min/max on the array will give you the requested
              result..

                  Hope I've got this one right, but I'd put the numbers in to an array,
                  perform a sort and then do an array_pop and an array_shift to take the first
                  and elements from the array - If either number was a zero, I'd perform the
                  the same routines again as they take the last and first element from the
                  array hence eventually you would get the lowest and highest number.

                  I've not tested this idea though for negative numbers but hope it gives you
                  some direction.
