Is this proper coding?

[Boofo]

Can someone tell me in their opinion if this is proper coding? The following code is the fix for the division by zero error.

I am replacing this:

if ($totalthreads == 0)
{
    $totalthreads = 1;
}
if ($totalposts == 0)
{
    $totalposts = 1;
}

With this:

$totalthreads == 0 ? $totalthreads = 1 : $totalthreads; 
$totalposts == 0 ? $totalposts = 1 : $totalposts;

It works, but I am curious as to what your feelings are as to whether this is actually a proper way to do it or not.

Can anyone tell I got bored enough to do this?
