changing - editing arrays!

[deepode]

Hi, guys!
I have 2 arrays, $inHand[] and $inBag[] ..... as name inHand are weapons in hand and inBag are weapons in bag.
Now, i want to give user ability so they can change their weapons. (User can't have more than 6 weapons so they need to change).
So if one wants to change his third weapon with 5th weapon in bag, i have to edit arrays but how do it?

I am sure that i haven't completely explained but hope it was enough... just tell me how to change one array with other array's some position and return it ?

Yup, Really confused.
Thanks in advance.

this was a fun, yet simple exercise:

    $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>";

WOW! Thanks! It worked!
however i had to think for a bit about how getting arrays back.... at last i got it... like..

$inHand = $swap["HAND"];
$inBag = $swap["BAG"];
