(3.0.13 - 3.0.18 only, PHP 4 >= 4.0.0)

krsort -- Sort an array by key in reverse order

## Description

``int krsort` (array array [, int sort_flags])`

Sorts an array by key in reverse order, maintaining key to data correlations. This is useful mainly for associative arrays.

Example 1. krsort() example
    $fruits = array ("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
    krsort ($fruits);
    reset ($fruits);
    while (list ($key, $val) = each ($fruits)) {
        echo "$key = $val\n";
    }

This example would display:

    d = lemon
    c = apple
    b = banana
    a = orange

You may modify the behavior of the sort using the optional parameter `sort_flags`, for details see sort().
