28. Reverse Sort Array

Write a PHP script to sort an array in reverse order (highest to lowest).

Sample Solution:

PHP Code:

<?php
// Define an array of colors
$colors = array("Red", "Orange", "Black", "White");

// Sort the array in reverse order (descending)
rsort($colors);

// Display the sorted array
print_r($colors);
?>

Output:

Array                                                       
(                                                           
    [0] => White                                            
    [1] => Red                                              
    [2] => Orange                                           
    [3] => Black                                            
)
