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().
