Hi, I'm currently writing a mulit-page form app that uses a session to
retain data from each form element in order for the user to jump
between pages, then the final data is passed to a calculation script.
However, I've noticed that if I assign a session variable to another
variable, which then performs a mathematical calculation, the session
variable changes.
i.e. $_SESSION["inflation"] = 4;
$temp_inf = $_SESSION["inflation"];
if ($_SESSION["inflation"] =="RPI") {
$inflation = $rpi;}
else {$inflation = ($temp_inf/100.0);}
now it equals = 0.04
How can I take a value from a session and perform operations on it
without altering the original session value.
Rgds
Neil.
