How to use rsort() Function In PHP
The rsort() function sorts an array in descending order. Like sort(), it does not maintain the original keys.
Example: This example shows the implementation of the above-explained approach.
<?php
// Create an Array
$arr = [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5];
// Function to sort array in
// descending order
rsort($arr);
print_r($arr);
?>
Output
Array
(
[0] => 9
[1] => 6
[2] => 5
[3] => 5
[4] => 5
[5] => 4
[6] => 3
[7] => 3
[8] => 2
[9] => 1
[10] => 1
)
