rsort — Sort an array in reverse order


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.

Palauttaa TRUE onnistuessaan, muutoin FALSE.

Example#1 rsort() example

= array("lemon""orange""banana""apple");
foreach (
$fruits as $key => $val) {
"$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().
