I have an array like this $perfs = $_POST['perfs'], which a couple of numbers.
$diff = $perfs - $perfs;
but that results in: $diff => 2
What I'm looking for is: $diff => 262
when I echo $perfs, I get 3 not 1344799479334
when I echo $perfs, I get 1 not 1344799479072
How can I access my original values?
