overloading function params?

[jake13jake]

I remember a while ago I was told that something such as the following would possess the same qualities as overloading functions (and I'm pretty sure it was from Stefan). However, now that I've found a place where I want to use it, I find that params aren't even loading into the function.

PHP Code:

function myFunction() {
  switch (params.size()) {
  case 1:
  case 2:
  case 3:
  default:
  }
} 


Here is the script that I am working with.

PHP Code:

function dropitem() {
  player.chat = params.size();
  switch (params.size()) {
  case 1:
     temp.dropitem = params[0];
     break;
  case 2:
    temp.tpercents = params[1];
    for (i=0;i<temp.tpercents.size();i++)
      tpercents[i] += tpercents[i-1];
    temp.choice = random(0,100);
    for (i=0;i<temp.tpercents.size();i++) {
      if (temp.choice <= temp.tpercents[i]) {
        temp.dropitem = params[0][i];
        break;
      }
    }
    break;
  }
  if (temp.dropitem) {
    putnpc2(x-1,y-1,"join dropitem_"@temp.dropitem@";");
  }
} 


I would have revived the thread that this was said in, but I can't find it. Unfortunately, I guess I'll have to go about other methods. If I'm just screwing things up, please help me. If not, move this to the future improvements forum or something.
