No, you don't want to do that. The " are designed as enclosures (although the third parameter isn't necessary at all) and exist only when wrapping data that includes the ,. If you do that it will only seek to separate on "," instead of ignoring , which is surrounded by ".
Unless the user is looking for 13 results based completely on the ,? If that's the case, than an explode of the whole line would be easier.
Actually, according to the doc you cannot do that anyways. The delimiter is only a char, not a string.
