Subtracting?

[Inkybro]

Okay, this is another thing about the "money" on my site. I want it to subtract so much when they click for instance a button/link, how would I do that?

[hand]

$money = $money - $selectedValue;

This would SUBTRACT it right not SET it?

Well $money (in hand's example) would now equal the difference between both variables.

$money = "5";
$selectedValue = "2";

$money2 = $money - $selectedValue;

// in other words
// $money = 5 - 2
// $money = 3

Then you can do what you want with that variable whether it be display it or input into a database.

If you don't want to "set" a variable, then do

$money = "5";
$selectedValue = "2";

echo $money - $selectedValue;
