Add array range to new array

To get back in to scripting things other than GUIs and HP systems, I've decided to try and recreate PHP's explode() and implode() functions. I'm wondering, however, is there already an existing way to add an array range to a new array? Or will I have to script my own?

For instance, explode() has three parameters: delimiter, string, limit. If limit is set to a positive number that is less than the string's length when tokenized by the delimiter, it will add each token, with the last one containing the rest of the string. So, if my string is "1,2,3,4,5", my delimiter is ",", and my limit is 3, the output would be: {1, 2, "3,4,5"}.

I don't believe there is already an explode() or implode() function.

I'd imagine you could do one like this:

PHP Code:


		
			
echo(explode(",", "1, 2, 3, 4, 5, 6", 3));

PHP Code:


		
			
function explode(del, str, limit) {
  temp.token = str.tokenize(del);
  for (temp.i = 0; temp.i < token.size(); temp.i ++) {
    if (i < limit) {
      temp.output.add(token[i]);
    }else {
      temp.positions = str.positions(del);
      temp.output.add(str.substring(positions[i - 1] + 1));
      break;
    }
  }
  return output;
}

Good luck.

That's exactly what I was looking for. Thank you, Tig. Though, for anybody thinking about using the script Tig provided: it's not the complete explode() function, as in PHP. I'll release mine publicly as soon as I finish it.

What is explode be useful for? I've only ever done work in GS2 so this sort of stuff I've never heard of before. :p

It converts a deliminated string to an array. Useful if you want to work with individual portions of a string without using messy string manipulation functions.
