Answer 1

I wouldn't call it dirty per se, it seems valid enough. But I can't think where I would use that function. My only suggestion might be to include else:

function intcmp($a,$b)
{
    if((int)$a == (int)$b)return 0;
    else if((int)$a  > (int)$b)return 1;
    else if((int)$a  < (int)$b)return -1;
}
