changing – editing arrays!

@OctoberWindNov 05.2012 — #this was a fun, yet simple exercise:

[code=php]
  $inHand = array(1=>"knife", "pistol", "shotgun", "lanten", "map", "compass");		// the stuff in your hand
 $inBag = array(1=>"rope", "radio", "grenade", "sword", "shovel");				// the stuff in your bag
 
  // function takes the two gear arrays, as well as the numeric keys for the "old" and "new" items
  function switch_gear($hand, $bag, $oldItemKey, $newItemKey) {
 
   $transfer = $bag[$newItemKey];	// get the new item from the bag
   $drop = $hand[$oldItemKey];		// "drop" the old item from your hand
 
   $hand[$oldItemKey] = $transfer;	// put the new item in your hand
   $bag[$newItemKey] = $drop;		// put the old item in your bag
 
   $returnArray["HAND"] = $hand;
   $returnArray["BAG"] = $bag;
 
   return $returnArray;	// return both the "hand" and "bag" arrays
  }
 
 
  $swap = switch_gear($inHand, $inBag, 3, 5);
 
  echo "n<pre>";
  echo "nHand: ".print_r($inHand);
  echo "nBag: ".print_r($inBag); 
  echo "n Return: ".print_r($swap);
  echo "n</pre>";
 
 [/code]
