That's still pretty nasty though:
<?php
<snip>
salestax(15.00,.075);
salestax(15.00,.075);
?>
gives:
Total cost in dollars: 16.125. Cost in British pounds: 25.8
24
Fatal error: Cannot redeclare convert_pound() ...
What's wrong with non-nested functions? i.e.:
function convert_pound($dollars, $conversion=1.6) {
return $dollars * $conversion;
}
function salestax($price,$tax) {
$total = $price + ($price * $tax);
echo "Total cost in dollars: $total. Cost in British pounds: "
.convert_pound($total);
}
