It works with all types (just as well as <, <=, >=, > work) and is great
for usort() callbacks for example.
Why not using
$a - $b instead of
$a <=> $b?

And when you’re sorting objects, you probably want to be doing
the comparison on some string/numeric property.
Agreed! It would make more sense to write a comparison function for arrays/objects.
