Hey there!

How can I calculate till 2 decimals after the comma?

I've got something like this now

$price1 = array_sum($prices);
$test = $price1 * 0.7;
echo $test;

Now I'm getting values like 32.233 or 500.300, but they should be 32,23 and 500,30 :s

Also, have a look at [a href=\"http://www.php.net/number_format\" target=\"_blank\"]number_format() function[/a]

eg

$test = 32.4567;

echo number_format($test, 2, ',', '');

--> 32,46
If you are still using mysql_ functions, STOP! Use mysqli_ or PDO. The longer you leave it the more you will have to rewrite.
