I'm not sure, if I understood, but try this:
<?php
$items = array (
0 => array ("item"=>"car","price"=>10000,
"tax"=>0.06 ),
1 => array ("item"=>"pencil","price"=>1,
"tax"=>0.06 ),
2 => array ("item"=>"book","price"=>14.95,
"tax"=>0.065)
);
function GetTax($item){
return $item["price"]*$item["tax"];
}
function GetBalance($item){
return $item["price"]+GetTax($item);
}
function ShowPrice($price){
return sprintf ("%.2f", $price);
}
$balance=0;
if(sizeof($items)) foreach($items as $item){
$balance+=GetBalance($item);
echo
$item["item"]." ".ShowPrice($item["price"])." &n
bsp;".ShowPrice(GetTax($item))." ".ShowPrice($balance)."<br
>\n";
}
?>
