If you have a numerically indexed array with some keys missing, ie 1, 2, 4,
5 and you want to reindex it so it's 1,2,3,4 *without changing the
positions of the values* (ie sort()) then you can use this function to do
it.

Indeed you can, and that's what's so great about it. I have, for instance,
a function that returns the results of a database query as an array. I want
to keep the order that the entries were returned in, but at the same time I
want to be able to access them _either_ by the position _or_ by some other
index (such as some sort of ID in the database, gotten from elsewhere). In
this case, I can make the function return an array from id to [array of
values], and by a simple call to array_values() this is transformed into an
array indexed from 0 to count()-1. Useful.
