Many thanks to both. The two solutions worked beautifully. The one proposed by elixir_sinari is faster and as he himself states
With perl (without invoking the interpreter twice and without calling any external utility):
Thanks for the quick postings and the useful code. I learned finally how to handle scalar reverse, which is a great learning experience for me.

rsort - Sort an array in reverse order

SYNOPSIS
bool rsort (array &$array, [int $sort_flags = SORT_REGULAR]) DESCRIPTION
This function sorts an array in reverse order (highest to lowest). PARAMETERS
o $array - The input array. o $sort_flags - You may modify the behavior of the sort using the optional parameter $sort_flags, for details see sort(3). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 rsort(3) example <?php $fruits = array("lemon", "orange", "banana", "apple"); rsort($fruits); foreach ($fruits as $key => $val) { echo "$key = $val "; } ?> The above example will output: 0 = orange 1 = lemon 2 = banana 3 = apple The fruits have been sorted in reverse alphabetical order. NOTES
Note This function assigns new keys to the elements in $array. It will remove any existing keys that may have been assigned, rather than just reordering the keys. SEE ALSO
arsort(3), krsort(3), The comparison of array sorting functions. PHP Documentation Group RSORT(3)
