# krsort

(PHP 3>= 3.0.13, PHP 4 , PHP 5)

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.

成功回傳`TRUE`失敗回傳`FALSE`。

範例 1. krsort() example

`<?php $fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple"); krsort($fruits); reset($fruits); while (list($key, $val) = each($fruits)) { 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().
