krsort — Sort an array by key in reverse order

### Description

bool 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.

Returns `TRUE` on success or `FALSE` on failure.

Example#1 krsort() example

`<?php
$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
krsort($fruits);
foreach ($fruits as $key => $val) {
echo "$key = $val\n";
}
?>`

The above example will output:

    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().
