I'm positive that it will always be set, 'cause I set it. It's just going the comparison.
if($var) used to work for if($var != 0) or if($var != "0") but that doesn't seem to work since I upgrade. So I'm just going to do if((int)$var) from now on, 'cause that should always work. I'll typecast everything that being compared to and int to make sure.
