i have the code below where i am trying to traverse a two dimensional array using list() and each(). i was wondering if anyone can help. i am getting 3 warnings:

Warning: Variable passed to each() is not an array or object in ... line 44

output is as follows:

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

  Warning: Variable passed to each() is not an array or object in /users/../useractivepreviewtmp284.php3 on line 44

Total (including tax and shipping): $0.00

Code is as follows:

<B>Checkout</B><br>
Below is a summary of the products you wish to purchase, along with totals:

<?php


$total_price = 0;
$total_tax = 0;
$total_shipping = 0;
$grand_total = 0;
?><ul><?

//2 dimensional array that acts as a DB and stores Name, Price and Shipping (as a % of price) for every given item,
$product = array( array(Name => "Candle Holder",
							Price => 12.95,
							Shipping => 0.0 //free shipping
							),
				 array(Name => "Coffee Table",
							Price => 99.50,
							Shipping => 0.10 //shipping as a % of price
						),
				 array(Name => "Lamp",
							Price => 42.99,
							Shipping => 0.10 //shipping as a % of price
							));


for($row = 0; $row < count($product[$row]); $row++ )
{
	while (list($key, $val) = each($products[ $row ] )) 
	{
		echo "$key => $val\n";
	}
}

/*
	Purpose: function CALCulates a total (incl. tax) price payable by the consumer a given item
	INPUT: price and shiping for each item
	OUTPUT: total price which includes tax
*/
function calc_total($price, $shipping)
{
	#tax rate is constant
	$tax = 0.08;
	$total_price += $price;
	$total_tax += $tax * $price;
	$total_shipping += $shipping * $price;
	$grand_total = ($total_price + $total_tax + $total_shipping);

return $grand_total;
}
?>
</ul>
<hr>

<B>Total (including tax and shipping): $<? echo number_format($grand_total, 2); ?></B>

I would use foreach()

foreach($product as $prod){
	foreach($prod as $key=>$val){
		echo "$key => $val\n";
	}
}

i am looking at it now and i am not sure how this code works...
do you mind explaining me what does '$product as $prod' and '$prod as $key=>$val' do?

thank you very much 🙂

thank you very much for your help once again 🙂

the problem is in my project i was meant to use list() and each()

below is what i did in the end. i was wondering would you have any idea why my orig. code did not work?

thank you 🙂

=============================
foreach($product as $prod){
echo"<pre>";
// going through all the inner array's values in the inner loop
while (list($key, $val) = each($prod))
{
echo "<li>$key => $val\n";
/*
CODE FOR DEBUGGING ONLY

             echo "$prod[Name]<br>";
             echo "$prod[Price]<br>";
             echo "$prod[Shipping]<br>";
            */
}
// 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
$grand_total += calc_total($prod[Price], $prod[Shipping]);
echo"</pre>";

}

In that case you should be doing your own homework.

yes, i was doing it by myself. i just had a bug and could not figure out how to resolve it.

i did manage to complete the task. however, my original code still has a bug and i cannot figure out where i went wrong.
thank you
