next() and key() bug

Duke555

i have the following bug in my code (see below).
what i am trying to print values of the array it starts with a second value
i.e. 'coffee table' as opposed to a 'Candle Holder'. when i was using list($key, $val) = each($product); and then echo $key; it was exactly the same thing.
thank you 🙂

here is the output:
Checkout
Below is a summary of the products you wish to purchase, along with totals:

  Coffee Table
* Price => 12.95
* Shipping => 0

  Lamp
* Price => 99.5
* Shipping => 0.1


* Price => 42.99
* Shipping => 0.1

Total (including tax and shipping): $182.12

Hi there,

Here is the code you need to use:

foreach($product as $product_name => $product_info)
{
	echo"<pre>";
	echo $product_name."<br>";

// DELETE THIS LINE >>>> next($product);

while (list($key, $val) = each($product_info))
{
	echo "<li>$key => $val";

}
// accessing Price and Shipping for each inner array and sending these values to a calc_total
// function which is going to make a total calculation
$grand_total += calc_total($name[Price], $name[Shipping]);
echo"</pre>";
}

I hope this helps you. Please let me know.
