removing an item from basket

[miztas]

I want to remove items from a basket, so far I have:

$price = $array['price'];

if($trolley[$game_code]){

$trolley[$game_code]--;

$total = $total - $price;

if($trolley[$value] == 0){
unset ($trolley[$game_code]);
}

}
else
{
unset ($trolley[$game_code]);
}

but this seems to remove all items, not individual.

I don't know if I get it right,

unset ($trolley[$game_code]);

It will only remove that element from the array, not the whole array.
