Reverse the order of an index of numbers in php

Question

my script :

$reverse_sets = array_reverse($sets);
foreach ($extraset as $element) {
    foreach ($sets as $index => $set) {
        if (in_array($element, $set)) {
            $actual_index = count($sets)-$index-1;
            echo "Extraset element '$element' is in set $actual_index<br>";
            break;
        }
    }
}

outputs me an $actual_index serie of numbers, from 20 to 0.

I need to reverse the output of $actual_index displaying the numbers backwards (from 0 to 20), without touching the previous logic of the script.

I tried using again array reverse on $actual_index, creating $final_index :

$reverse_sets = array_reverse($sets);
foreach ($extraset as $element) {
    foreach ($sets as $index => $set) {
        if (in_array($element, $set)) {
            $actual_index = count($sets)-$index-1;
            $final_index = array_reverse($actual_index);
            echo "Extraset element '$element' is in set $final_index<br>";
            break;
        }
    }
}

but i don't get any output.

What is wrong with my code ? How do I fix this ? thanks for your help

You can use php function array_reverse to reverse your final array. — Rahat Hameed, Jul 14 '21 at 13:50
As you can see in my try, i used array_reverse on $actual_index , creating a $final_index, but i get no output — Francesco, Jul 14 '21 at 14:30
