Help finding value of array

[webreadyaudio]

I've built a simple shopping cart and need to generate the total shipping from the array. Here is code so far.

    <?
    while (list($key, $val) = each($_SESSION['cart'])) {
        $this_item = $key;
        $this_item_qty = $val;
        echo ('<tr valign="top">');
            echo ('<td>' . $items[$this_item].'</td>');
            echo ('<td align="right">$');
            echo (number_format($prices[$this_item],2));
            echo ('</td>');
            echo ('<td>');
                if(!$this_item_qty) {
                    $this_item_qty = 1;
                }
                echo $this_item_qty;
            echo '</td>';        
            echo ('<td>$'. $shipping[$this_item] .'</td>');
            $this_line_total = $this_item_qty * (number_format($prices[$this_item],2) + $shipping[$this_item]);
            echo ('<td>$'. number_format($this_line_total,2) . '</td>');
        echo ('</tr>');
        $total = $total + $this_line_total;
                          $shippingtotal = // BLAH, BLAH ??
    }?>

So there may be 2 items listed in the cart, and I'm getting their individual totals with shipping, but want to create a seperate line and output the total charge for shipping alone.

i didnt look too closely at your code, but i guess you have an individual shipping charge per item.

here is the logic.

$shipping_total = 0;

while(...) {
    $shipping_total =+ $shipping_charge_for_this_item;
}


echo $shipping_total;

Thanks clamcrusher, however I'm still not getting this.

I am already inside a while loop. When I try another while loop it times out.

I tried this

if($items[$this_item] < 1 ) {
                $shippingtotal = + $shipping[$this_item];
            } 

Basically I'm trying to say if their are more than one items in the cart then add the get the total shipping. Each product has a different shipping charge.

btw i made a typo, it should be += not =+

 $shipping_total = 0;

while (list($key, $val) = each($_SESSION['cart'])) { 
    // your other code...
    $shipping_total += $shipping_charge_for_this_item;
    // your other code....
}


echo $shipping_total;

Thank you very much, I got it to work. I was under the impression I needed to do some sort of count for that array.
