One small thing that could come back to bite you in the butt down the road is using $a for a variable since $a and $b are special variables.
I'd change it to something a bit more meaningful so not only that you'll remember what it does when you look at the code 6 months from now but you won't get messed up if you use the <=> operator in the program down the road.
