Why doesn't the first one give me an answer of 0 instead of 1. I know I could
do a IF $data == "[empty]" and then not count if its empty and just set it
to 0, but am wondering if there was a better way.
Because explode divides the string in n+1 elements, where n is the amount
of "," (or your favorite delimiter) found in the string. So if no "," is
found, explode will return 1 element: the whole string (even if it's
empty).
