Description

bool rsort ( array &$array [, int $sort_flags= SORT_REGULAR ] )

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

Parameters

array

The input array.

sort_flags

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

Return Values

Examples

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.

Notes

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