To replace each whitespace in a streak of whitespaces excluding the first whitespace, use

preg_replace('~(?<=\s)\s~', '&nbsp;', $myString)

See the regex demo.

It will turn A B C D E into A B C &nbsp;&nbsp;D &nbsp;&nbsp;&nbsp;&nbsp;E.

Your /\s(?=\s)/ lookahead solution will replace all whitespaces but the last one in a streak of whitespaces, as the positive lookahead requires the presence of the pattern immediately to the right of the current location, whole the lookbehind will look for a match to the left of the current location.
