Re: Arrays past to functions

You don't really need an array here. function ComputeSalesTax($Amt, $State) { switch ($State) { case "CA": $tax = 1.05; break; case "WA": $tax = 1.07; break; // etc. default: $tax = false; } if ($tax != false) { return ($Amt * $tax); } else { die("State not found!"); // or some other graceful method... } } ComputeSalesTax(2000, "CA"); // returns 2100 ComputeSalesTax(2000, "LA"); // fails -- Jarrett M.

Say using CA, WA, and OR, and setting there tax rates at, whatever, say 5%, 7%, and 8% respectively. I want a function I can pass the array of states, and tax rates to that will display the total amount (amount + tax) of say a $1500 purchase. I am trying to use a switch statement to accomplish this, but I think I may be in over my head trying to do this with what I have learned so far... Here is the code I have so far I get 0 every time I run it, try not to laugh... :-) Thanks guys. $State = array ("CA" , "WA" , "OR"); function compute_salestax ($Amount , $State) { switch ($State) { case "CA" : $Rate = "1.05"; break; case "WA" : $Rate = "1.07"; break; case "OR" : $Rate = "1.08"; break; } global $Rate; $Truetax = ($Amount * $Rate); echo "$Truetax <br />"; } $Amount = 1500; compute_salestax($Amount , $State); Jacob Bergman Network Technician Pullman School District #267 (509) 432-4012 jbergman@psd267.wednet.edu
