Array arsort to sort in reverse |
See the asort array function first. The function arsort changes the elements and arrange them in reverse alphabetical order. Here in arsort the order is just opposite than asort.
By using arsort function we can retain the index or indices associated with elements of the original array.
Here is the example code. We have only changed the function asort to arsort.
<?
$input = array ("Pinaple", "Orange", "Banana", "Mango", "Apple","Strawberry");
while (list ($key, $val) = each ($input)) {
echo "$key -> $val <br>";
}
arsort($input);
echo "<br>-----After arsort---------<br>";
while (list ($key, $val) = each ($input)) {
echo "$key -> $val <br>";
}
?>
Here is the output of arsort function
0 -> Pinaple 1 -> Orange 2 -> Banana 3 -> Mango 4 -> Apple 5 -> Strawberry -----After arsort--------- 5 -> Strawberry 0 -> Pinaple 1 -> Orange 3 -> Mango 2 -> Banana 4 -> Apple
