I'd personally do something like have a class called "party" or whatever else you want to name it with a few functions like addPlayer, removePlayer, getPlayers, invitePlayer etc.

then create a party by doing something like

PHP Code:

function newParty(){
  temp.party = new TStaticVar("Party_"@player.account);
  party.join("party");
  party.addPlayer(player);
} 


then in the class

PHP Code:

public function addPlayer(pobj){
  pobj.party = this;
  this.members.add(pobj);
} 


then when a player wants to invite someone, imagine by some chat command on the client that triggers the server with the account name

PHP Code:

function onActionServerside(cmd, target){
  if(cmd == "inv"){
    player.party.invitePlayer(findplayer(target));
  }
  if(cmd == "create"){
    newParty();
  }
}
