RE: [PHP] Having trouble formatting width using printf() and defa ult spaces From: Martin Towell (martin.towell <email protected>)
Date: 03/31/04

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 &nbsp; as the space
character, however, you can use sprintf() and str_replace() together to do
the same effect.

Try this:
     echo str_replace(" ", "&nbsp;", sprintf("%10u", rand(1,$sides)));
