krsort: Sorting Key by reverse order

We have seen how the ksort function sorts the array based on the keys of the element. By using krsort we can just reverse the order of the keys. Here also we have retained the data key association after the krsort function.

Let us try with some examples.

<?Php $input = array ("b" => "Pinaple", "d" =>"Orange", "a" =>"Banana", "c" =>"Mango", "f" =>"Apple","e" =>"Strawberry");
while (list ($key, $val) = each ($input)) {
echo "$key -> $val <br>";
}
krsort($input);
echo "<br>-----After krsort---------<br>";
while (list ($key, $val) = each ($input)) {
echo "$key -> $val <br>";
}
?>

The output of the above code is here

b -> Pinaple
d -> Orange
a -> Banana
c -> Mango
f -> Apple
e -> Strawberry

-----After krsort---------
f -> Apple
e -> Strawberry
d -> Orange
c -> Mango
b -> Pinaple
a -> Banana
