Using this array you need something like this
<?php
$items = array (
0 => array ("item"=>"car","price"=>15000, "tax"=>.065 ),
1 => array ("item"=>"pencil","price"=>1, "tax"=>.065 ),
2 => array ("item"=>"book","price"=>14.95, "tax"=>.065)
);
function getTax($cost,$taxrate){
return $cost * $taxrate;
}
echo '<table border="1">';
echo '<tr><td>Item
number</td><td>Item</td><td>Cost</td><td>Tax</td><td>Total</td></tr>';
$total = 0;
foreach($items as $key=>$item){
echo '<tr>';
echo '<td>'.($key+1).'</td>';
echo '<td>'.$item['item'].'</td>';
echo '<td>'.$item['price'].'</td>';
$tax = getTax($item['price'],$item['tax']);
echo '<td>'.$tax.'</td>';
$total += ($item['price'] + $tax);
echo '<td>'.$total.'</td>';
echo '</tr>';
}
echo '</table>';
?>
You will need to add number formatting but you get the idea.
I always store money as cents in the database and leave them as integers.
Just /100 to display
