sort() does not appear to work for arrays that have only a single element. I am using dynamically built arrays and when an array happens to have a single element it does not get touched by sort.

This makes sense as far as Why would I want to sort an array with a single element?  Because I want the indeces reset, not just the values sorted.  If an array has this structure:

array(1) { [3]=> string(9) "Baltimore" 

then it will not be touched at all by sort and will not be re-indexed to start at 0.  

It would be nice if sort would sort single element arrays.
