# rsort

(PHP 3, PHP 4, PHP 5)

rsort -- Sort an array in reverse order

## Description

bool rsort ( array &array [, int sort_flags] )

This function sorts an array in reverse order (highest to lowest).

> Note: This function assigns new keys for the elements in array. It will remove any existing keys you may have assigned, rather than just reordering the keys.

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

Example 1. rsort() example

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

The above example will output:

    0 = orange
    1 = lemon
    2 = banana
    3 = apple

The fruits have been sorted in reverse alphabetical order.

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