Description
void arsort
(array array);
This function sorts an array such that array indices maintain
their correlation with the array elements they are associated
with. This is used mainly when sorting associative arrays where
the actual element order is significant.
Example 1. arsort() example 1
2 $fruits = array ("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
3 arsort ($fruits);
4 for (reset ($fruits); $key = key ($fruits); next ($fruits)) {
5 echo "fruits[$key] = ".$fruits[$key]."\n";
6 }

This example would display:
fruits[a] = orange
fruits[d] = lemon
fruits[b] = banana
fruits[c] = apple
The fruits have been sorted in reverse alphabetical order, and
the index associated with each element has been maintained.
