First off, please try to refrain from cross-posting, especially to that
degree.
I'm not sure I interpreted the your intentions correctly. If not, could you
try to be a little more precise in saying what you _want_ the code to do?
The first thing that jumps out at me is in the function getTax. Shouldn't it
be getTax($value)? As you have it, value will be unset (search for variable
scope in the manual). I think this may be what you're going for:
function getTax($value) {
return ($value * 0.065);
}
Next, the list construct will only work with numeric arrays, not associative
ones. In other words, it has to look like array('one', 'two'), not
array('one' => 'two', 'three' => 'four')
Next the way you have it set up, $mypurchases can only contain one set of
three items. I don't get the logic of how car, pencil, and book map to $key,
$value, and $tax.... Maybe you were going for
$mypurchases = array(
'car' => 15000,
'pencil' => 1,
'book' => 14.95);
$total = 0;
echo '<table><tr><td>Item</td><td>Cost</td>';
echo '<td>Tax</td><td>Running Total</td></tr>';
foreach ( $mypurchases as $key => $value) {
$total += $value + ($tax = getTax($value));
// assuming you want the table in HTML, since you have a <br/>...
echo "<tr><td>{$key}</td><td>{$value}</td>";
echo "<td>{$tax}</td><td>{$total}</td></tr>\n";
}
echo '</table>';
???
I'm going to ignore the getBalance function because I don't think it's
required. But you realize your declaring a static variable, then trying to
assign a different value to it on the very next line?
