    I need to express:
    if($i!=){
    PHP:
    $i shouldn't be a multiple of 10.

    if (substr($i,-1))
    {
    echo "Im not a multiple of 10";
    }
    else
    {
    echo "I am";
    }

    Should work - basically testing of a 0 as the last digit - anything else will hit the if - the 0 will hit the else

    let me know fi that works

    or I suppose you can do a mod10 on it also if ($i%10) {not a multiple of 10}else {it is}

    That's the thing no need to have to test !=

    If it returns 0 it's false everything else is true.
