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