[SOLVED] Positives and Negatives

[rascle]

I have a variable that sometimes can be a negative and sometimes a positive but i want to output it so it is always a positive. How do i do this. I tried using abs() but didnt get anywhere.

Thanks

abs() should work. Can you show us some code?

[rascle]

i dont quite know how to use abs() but this is what someone told me it should be:

$logoutday = $logged[logoutday];
$currentday = date("d");
$days = $currentday - $logoutday;
$days=abs($days);

Thanks

That should work fine. Once you echo $days it should always be positive unless you change the value again before echoing.
