Counting items in basket inc. quantities

[boognish]

I writing a little script to count the total number of items in a shopping basket. It's fairly straight forward counting the amount of different items, but the problem I'm having is counting the items with more than 1 as the quantity. The code below generates the go to checkout button, but I'm also using it to get the number of items in the basket.

for($i=0; $i < count($cartContents); $i++){
$val = $i + 1;
$counting = count($cartContents);
$items .= "
     <input type='hidden' name='item_name_$val' value='". $cartContents[$i][1] ."' /> 
     <input type='hidden' name='amount_$val' value='". $cartContents[$i][3] ."' /> 
     <input type='hidden' name='currency_code' value='GBP' />
     <input type='hidden' name='quantity_$val' value = '" . $cartContents[$i][2] . "' />     
";
}

count($cartContents) - Gets number of different items
$cartContents[$i][2] - Gets the quantity of each item

Can anyone help me with the code to get the total number of items please?

I'm not quite sure what $counting is doing, but this will get you the total number of items:

$total_items = 0;
for($i=0; $i < count($cartContents); $i++) {
    $total_items += $cartContents[$i][2];
}

Hope that helps.
