Thanks, unfortunately, I don't really know what the whole
" if(is_array($State))
{
$total = 0;
foreach($State as $s)
{
$total += ComputeSalesTax($Amt, $s);
}
return $total;"
don't know enough yet to understand what all that means...
I have gotten the function to work the way I want using a for loop in
the function... but it doesn't seem to want to display the 0 keyed value
in the array. If you run this, you'll see what I mean. Can you tell me
what is wrong with it?
----------------------------------------------------------------------
$State = array ("WA" , "CA" , "OR");
function compute_salestax ($Amount , $State)
{
for ($i = 0 ; $i<= 2/*sizeof($State)*/ ; $i++)
{
switch ($State[$i])
{
case "WA" :
$Rate = "1.07";
break;
case "CA" :
$Rate = "1.08";
break;
case "OR" :
$Rate = "1.05";
break;
}
global $Rate;
$Truetax = ($Amount * $Rate);
echo "$i=";
echo "$Rate | $Truetax <br />";
}}
$Amount = 1850;
compute_salestax($Amount , $State);
---------------------------------------------------------------------
When I run it, I get this
---------------------------------------------------------------------
0= | 0
1=1.08 | 1998
2=1.05 | 1942.5
---------------------------------------------------------------------
Thanks for the help guys!
