krsort -- Sort an array by key in reverse order


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().
