Oh, I see. Perhaps something like this?

PHP Code:

function randomstring2(source, limit, repeat) {
  if(temp.limit == null) {
    temp.limit = temp.source.size();
  }
  if(temp.limit > temp.source.size()) {
    temp.limit = temp.source.size();
  }
  while(temp.i < temp.limit) {
    temp.trial = temp.source[random(0, temp.source.size())];
    if(temp.repeat) {
      temp.output @= temp.trial;
      temp.i++;
    }
    else {
      if(temp.output.pos(temp.trial) < 0) {
        temp.output @= temp.trial;
        temp.i++;
      }
    }
  }
  return temp.output;
}

Well, I provided a source array that contains all possible single characters. So, it shouldn't take too much time to edit it, if you're simply looking to generate something from a list of single characters. Arrays offer the possibility of doing something like this:

PHP Code:

function onCreated() {
  temp.source = {
    "test",
    "sources",
    "foo bar",
    "foo bar baz",
    "foo!bar!baz"
  };
  echo(randomstring2(temp.source, 3, true));
  echo(randomstring2(temp.source, 3, false));
} 


Which outputs:

foo!bar!bazfoo bar bazsources
