spaces in HTML are collapsed to a single space, that why you only see the
numbers seperated by a single space.
doesn't look like you can use printf() directly to use as the space
character, however, you can use sprintf() and str_replace() together to do
the same effect.
Try this:
echo str_replace(" ", " ", sprintf("%10u",
rand(1,$sides)));
