[RESOLVED] php4 OOP and References

[Neumy]

I'm sure this is a simple fix; just requiring an "&" in the right spot, but I can't figure it out, and all my searches don't help. Perhaps someone out there can enlighten me.

The base code I have is:

$nextPlayer = $Game->Fight->getNextPlayer($Game->Player);
$Game->Fight->setPlayerPosition($Game->Player,$nextPlayer);

In Game, I have:

   function setPlayerPosition(&$Player,$nextPlayer)
   {
      $speedMinus=0;
      $speedDelay=$nextPlayer['speedPosition'];
      foreach($Player as $val)
      {
         $speedMinus = $speedDelay;
         if($nextPlayer['id']==$val->playerID)
         {
            $speedMinus = $speedDelay +1;
         }
         $val->setSpeedPosition($val->speedPosition - $speedMinus);
      }
   }

And finally in Player, I have:

   function setSpeedPosition($newSpeed)
   {
      $this->speedPosition = $newSpeed;
      $query = "UPDATE `Player` SET `speedPosition`='$newSpeed' WHERE `playerID`=$this->playerID;";
      db_query($query);
   } // function setSpeedPosition()

Now, in PHP5 this works fine since they deal with references differently (halelujah). But since I have to downgrade this to php4, I can't seem to update Player properly. If I check the value of $Player[$i]->speedPosition before and after I call $Game->setPlayerPosition(), I get the SAME value, where it should have changed.

This HAS to be a reference problem, I just know it. But after I've put the "&" EVERYWHERE, it's still not working. Can someone help point me in the right direction?

Thanks big time!

I finally figured it out. Thanks to anyone that looked through my code.
This page helped me to figure out my problem: http://www.obdev.at/developers/articles/00002.html

The two things I did (I'm not really sure if the first one helped, but I'm not taking it out now):
1) Whenever I called a new Object: $Game =& new Game($db);
2) The foreach loop does not handle Objects well, I had to:

foreach(array_keys($Player) as $index)
{
   $tempPlayer =& $Player[$index];
   $speedMinus = $speedDelay;
   if($nextPlayer['id']==$tempPlayer->playerID)
   {
      $speedMinus = $speedDelay +1;
   }
   $tempPlayer->setSpeedPosition($tempPlayer->speedPosition - $speedMinus);
}
