Checkout Using 2D Array

[mythoslife]

I'm trying to convert this into 2d array using while, list, each...

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

#tax rate is constant
$tax = 0.08;
$total_price = 0;
$total_tax = 0;
$total_shipping = 0;
$grand_total = 0;
?><ul><?

//A function that does the calculations
function calculation($price, $shipping, $tax) {
$total_price += $price;
$total_tax += $tax * $price;
$total_shipping += $shipping * $price; 
$grand_total = ($total_price + $total_tax + $total_shipping);
return $grand_total;
}

//Items 
$product = "Candle Holder";
$price = 11.95;
$shipping = 0; //free shipping
echo "<li>".$product.": $".$price;
$grand_total += calculation($price, $shipping, $tax);

$product = "Coffee Table";
$price = 99.50;
$shipping = 0.10; //shipping as a percentage of price
echo "<li>".$product.": $".$price;
$grand_total += calculation($price, $shipping, $tax);


$product = "Floor Lamp";
$price = 44.99;
$shipping = 0.10; //shipping as a percentage of price
echo "<li>".$product.": $".$price;
$grand_total += calculation($price, $shipping, $tax);


?>

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

This is what I got so far but I got stock? Any ideas?

 $products = array( array( product => 'Candle Holder', 
             price => 11.95, 
             shipping => 0 
            ),
          array( product => 'Coffee Table', 
             price => 99.50, 
             shipping => 0.10 
            ),
          array( product => 'Floor Lamp', 
             price => 44.99, 
             shipping => 0.10 
            ) 
         );
		 
for ( $row = 0; $row < 3; $row++ )
{
 while (list($key, $value ) = each($products[$row]))
 {
  echo " | $value";
 }
 echo ' <br />';
}

Are you wanting to print out $products? If so, maybe something like.

for($i = 0; $i < count($products); ++$i)
    foreach($products[$i] as $key => $value)
        echo $value . "<br />";

Thank you that works. I'm looking to use a while loop instead that displays the products and later on can use it to calculate. Ugh. I'm so lost.

[mythoslife]

What I want to do is to traverse 2d array and calculate the product, the output should be:

• Candle Holder: 11.95

• Candle Holder: 11.95

Coffee Table: 99.5

• Floor Lamp: 44.99

TOTAL: (Total of the item above + shipping + tax)

Here's what I have so far:

$total_tax += $tax * $price;

$grand_total = ($total_price + $total_tax + $total_shipping);
return $grand_total;
}


$products = array( array( product => 'Candle Holder', 
             price => 11.95,

There's no attempt at error checking, but what about something like below?

$total = 0;

for($i=0; $i < count($products); ++$i)
{
   $p_tmp = 0; // price 
   $s_tmp = 0; // shipping

   while(list($key, $val) = each($products[$i]))
   {
       if($key === price)
          $p_tmp = $val;
       if($key === shipping)
          $s_tmp = $val;

       // output item info 
   }

   $total += compute($p_tmp, $s_tmp, $tax);
}

echo number_format($total, 2);

[mythoslife]

Thank you! This should work!

[mythoslife]

Do you have any ideas to take off the third item?

Item 1: $00.00: $0
Item 2: $00.00: $0
Item 3: $00.00: $0

Total = $some amount

Goal: is to not echo the third value or the shipping amount.

So far this is what I have using two nested while loop:

$products = array( array( product => "Candle Holder", 
             "price" => 11.95, 
             "shipping" => 0 
            ),
          array( product => "Coffee Table", 
             "price" => 99.50, 
             "shipping" => 0.10 
            ),
          array( product => "Floor Lamp", 
             "price" => 44.99, 
             "shipping" => 0.10 
            ) 
         );

while (list($key, $value) = each($products))
{
   $p_tmp = 0; // price 
   $s_tmp = 0; // shipping
 
   while(list($key2, $value2) = each($value))
   {
       if($key2 == "price")
          $p_tmp = $value2;
          
       if($key2 == "shipping")
          $s_tmp = $value2;      
       echo "$".$value2.": ";
   }
   echo "<br>";
   $grand_total += calculation($p_tmp, $s_tmp, $tax);
}

[divideby0]

by remove third item, do you mean not print the shipping value or do you mean to actually remove the third array in products? for the former, you might try something like

if($key2 == "price")
   $p_tmp = $value2;
  
if($key2 == "shipping")
   $s_tmp = $value2;

if($key2 == "product")
   echo $value2 . " ";
else if($key2 == "price")
   echo "$" . $value2;

the output I got was

Candle Holder $11.95
Coffee Table $99.5
Floor Lamp $44.99

for the latter, you *should* be able to use array_pop on products before you enter the outer while loop.

array_pop($products);

while(...)
{
   ...
}

[mythoslife]

I got it thanks for your help though.. this is what I figured:

while (list($key, $value) = each($products)) {
	echo '<li>'.$value['product'] . ': ' . $value['price'] . '<br />', "\n";
	$grand_total += calculation($value['price'], $value['shipping'], $tax);
